Features and benefits are:
- High power density
- Smaller dimensions and low height profile package for space saving
- Pad layout compatible with SMA packages
Parts are typically used in these applications:
- Over-voltage protection
- ESD protection
- Free-wheeling diodes
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.

MOSFETs
Diotec starts 2020 into the new era of offering (Power) MOSFET devices. With using advanced trench technology our MOSFETs reach a low RDS(on) and fast switching times which saves you energy and costs. You find the whole MOSFET portfolio in our MOSFET product overview.
The 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 small signal types can be used in all kind of battery and load management applications. They feature a low on-state resistance and come in a space-saving SMD package.
