Application Notes

Discrete Solutions for your Power Applications - Rectifiers in TO-220 and D²PAK

Discrete power components are state-of-the-art in various applications. They offer cost-effective, robust, easy to assemble and reliable solutions for many kinds of power circuits. Diotec’s product portfolio includes Standard, Fast, Superfast Efficient and Schottky Barrier Rectifiers. Single and dual diodes are available in both TO-220AC (2 pin) and AB (3 pin) packages and also in 2 pin and 3 pin D²PAK outlines (TO-263AA & AB).

Our proprietary Protectifiers® in TO-220 offer low forward voltage drop at high reverse robustness – protected rectifiers indeed!

Ultra Low Power LDO Voltage Regulator

DI6206 Series from Diotec is a high precision CMOS based low drop out voltage regulator. The device is compatible with low ESR ceramic capacitors. It provides output currents over 200 mA and fixed output voltages of 1.5 V to 3.6 V from an input voltage of 7.0 V. Special features like very low quiescent current and low dropout voltage enables usage in low power applications, and allows for longer operation times of battery-powered electronics. Parts include additionally a current limit and short-circuit protection.

Application Note about ESD Protection

Diotec offers a wide range of ESD protection diodes both in single line and dual line configurations in various packages ranging from general-purpose (SOD-323) to small-size 0201 packages, supporting a wide range of signal speeds. They can provide transient protection for data lines and I/O ports as per IEC 61000-4-2 (air and contact discharge).

Application Note about Power Supplies

Diotec offers a wide range of dedicated products for the use in 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 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.

3rd Generation Schottky for Energy Applications

Diotec's -3G Schottky Technology encompasses high power handling capability at small package outlines. It offers state-of-the-art performance in the field of Schottky Rectifiers. Energy savings are one common feature of all these new devices.

The new axial lead diode SBX3040-3G shows impressively what that means. It features a very low forward voltage and a low leakage current, and is thus perfectly suited for solar bypass diode applications. Its very low forward voltage drop Vf makes this part further ideally suited for reverse polarity protection in battery powered systems or automotive applications. Power losses can be reduced and thus energy saved. Our new flyer shows more dedicated Schottky Diodes for Energy Applications.
