Application Notes

Designers of Smart Meter, LED Street Lamps, 4G/5G Base Stations, EV Charging Systems and similar applications often face the issue of over-voltage transients, since all these devices are connected directly to the land line which is highly affected by lightning strikes. They are affecting the reliability and lifetime of these products, so the use of rectifier diodes with extra high safety margin against transient surges is mandatory.

The SM3000 by Diotec is especially developed for these applications. It offers an impressive reverse voltage of 3000V, an average forward current of 1A and comes in a single SMD Melf package. Due to the large clearance and creepage of this outline it can replace the usual series connections, which are still common for input rectification at the above applications. More in our actual Flyer.

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!

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.

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.
