New: 2A/1000V SMD bridge in slim SO-DIL package
Diotec completes its family of 2A SMD bridges in the slim SO-DIL package. Up to now these parts were available with a maximum reverse voltage Vrrm of 800V, now the 1000V version B500S2A-SLIM is available.
It features best-in-class performance with an output current of up to 2.3A at 25mm² solder pad area and 25°C ambient temperature. Forward surge current rating is maximum 65A at 50Hz/10ms half sine wave pulse.
The parts come in the low profile SO-DIL package measuring only 2.5mm of body height. Thus they can be assembled on the bottom side of the PCB, where space is usually restricted. Application is input rectification for any kind of power supplies, especially where higher current output is required.
Diotec adds Voltage Regulators to its Product Range
Our new linear voltage regulators are designed for high performance operation. They offer reliable solutions to generate stable output voltages for a wide range of input voltage conditions. Applications include medium power general-purpose consumer and industrial circuits such as DC/DC converters, battery chargers, LED drivers and µController (MCU) supplies.
Linear voltage regulators are used in sensitive applications and complex circuits, requiring stable supply voltages, low to medium current capabilities and low noise.
Depending on the type of function, parts are classified into four main families:
- Positive Voltage Regulators
- Negative Voltage Regulators
- Adjustable Voltage Regulators
- Fixed Voltage Regulators
Diotec offers these devices in industry-standard packages such as SOT-223, SOT-23, SOT-89, TO-92 and SO-8, with the following main features:
- Input Voltage Range: 7.0V … 40V
- Output Current Range: 0.1A … 1.0A
- Output Voltage Range: 1.25V … 24V
- Internal Current Limitation
- Short Circuit Protection
- Thermal Shutdown

New Application Note about Power Supplies
In recent decades, many efficiency standards have been developed worldwide to reduce global energy consumption and thus to lower CO2 emissions. This rapid development of standards requires highly efficient power supplies. For that purpose, the latest energy-saving technologies and components are to be used: From the input bridge via Power Factor Correction (PFC) to the switching stage such as flyback, forward, buck or boost topology and the output stage, all including protection and control circuits.
Diotec offers a wide range of dedicated products for almost every need:
- Three-phase Bridge Rectifiers such as the DBI25-18A, which stay "cool" under load and meet the surge voltage requirements of EN61000-4-5
- Controlled Avalanche Rectifiers in SMA and Melf packages like the AM2000, for the auxiliary stage or the use at highly disturbed input mains
- Super Fast Efficient Rectifiers like the MUR860 for Power Factor Correction
- Low RDS(on) and fast switching MOSFETs for the converter stage
- Bootstrap diodes for the upper gate driver supply, e. g. the SA265 or BYG23T
- The TVS/blocking diode combination TGL200U06 for the snubber circuit
- 3rd Generation Schottky Diodes, which ensure lower power losses at the output stage
- Voltage Regulators with internal current limitation and thermal shutdown
- Shunt Regulators such as the MMTL431A used as voltage reference and error amplifier
- Easy drive of signal LEDs with Current Limiting Diodes, e. g. the CL10MD
All these parts support designers in finding the best possible solutions with highest efficiency. Power losses are reduced, energy savings are increased and consequently the overall performance can be improved. Read all the details in our new application note about power supplies.
FX2000D: 20A/200V Low Vf Diode for Polarity Protection and Free-Wheeling
The FX2000D has a Vf of less than 940mV at 20A, which is lower than what typical 200V Schottkys can offer. This makes these parts ideally suited for medium voltage DC applications such as polarity protection or OR-ing diodes.
Its trr of less than 200ns makes it further suitable for low to medium frequency AC circuits, e. g. as free-wheeling diode in power tool switches, variable speed control of DC drives, in relays and magnetic coils. The part comes in an axial lead package with increased wire diameter for better heat dissipation.
The same characteristics are available in the case outline TO-220AC with two polarities: anode or cathode to tab. Here the part numbers are FT2000AD and FT2000KD.

First release of our new MOSFETs: DIT100N10, DI020N6D1, MMFTP3401
Diotec starts 2020 into the new era of offering (Power) MOSFET devices, produced in advanced trench technology. We are pleased to announce today the first three available parts:
- The DIT100N10 in TO-220AB package is a N-type Power MOSFET having a typical RDS(on) of 9.9mOhm, 100A of DC drain current and 100V of maximum Drain to Source voltage
- The DI020N06D1in D-PAK is a N-type power device having 24mOhm, 20A and 60V
- The MMFTP3401in SOT-23 package is a P-type high current Small Signal MOSFET with 65mOhm, 3A and 30V
The two power MOSFETs are ideally suited for DC/DC converters, DC drives and power tools, due to their very low on-state resistance and extremely fast switching times. They offer a reverse avalanche characteristic for safe operation and require low driving effort due to their low gate charge.
The high current small signal P-type can be used in all kind of battery and load management applications. It features a low on-state resistance and comes in a space-saving SMD package. Samples of all three types are available from stock and can be ordered here.
SBT1045-3G and SBT1845-3G: 3rd Generation Schottky in TO-220AC
The SBT1045-3G and the SBT1845-3G are Power Schottky Rectifiers built in Diotec's 3rd generation chip technology. They come in the TO-220AC package and offer forward currents of 10A and 18A respectively.
Compared to the previous generation, they offer a reduction in forward voltage and thus power losses of up to 10%. Reverse leakage current at 45V could be reduced to less than 120µA. Typical applications include output rectifiers in AC/DC and DC/DC converters, polarity protection for batteries and free-wheeling diodes in low voltage DC drives.
TGL200CU08: Combined TVS and Ultrafast Diode save space in Flyback Converters
Flyback converters are the state-of-the-art choice for auxiliary power supplies, LED drivers and battery chargers. Their topology requires a special network, the so called snubber at the primary side, in order to protect the MOSFET respectively switching IC against excessive voltage spikes.
The snubber usually consists of a TVS diode and an Ultrafast rectifier; depending on switching frequency also a Fast or even Standard Recovery type might be used.
The TGL200CU08 by Diotec combines a 200V TVS and a 800V Ultrafast diode in a single DO-213AB/Melf package. It thus helps to save board save in this usually rather tightly assembled circuits. Further available are the Fast Recovery version TGL200CF08; a Standard Recovery version is under development.

Based on the current trend, investments in R&D by major OEMs make it evident that there will be a significant growth in the lighting sector.
In Automotive industry particularly in lighting segment a new era came with the light emitting diodes (LED). Due to their advantages like smaller size, high efficiency, lower energy consumption and thus fuel efficiency, long service life and design freedom, LEDs are becoming a more popular choice to replace traditional lamps.
Their small size and design flexibility let them fit very well in the interior lighting, creating comfortable ambience and good mood, which improves the concentration of the driver. While in the exterior lighting, the laser headlight, LED/OLED matrix are added to the high beam, promoting higher luminance and greater visibility, to enhance safety driving.
Discrete components always provide flexibility in choosing the perfect match based on the circuit requirements. By choosing the best suited semiconductor components in the design, power losses decrease and energy savings can be pushed even further. Hence, the selection of the right components can also boost-up the overall performance.
