STMicroelectronics reveals new family of 100V trench Schottky rectifier diodes for increased efficiency and power density

STMicroelectronics has introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies.

Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, including silicon Schottky devices, used as rectifiers become a significant factor limiting conversion efficiency.

ST’s trench Schottky diodes significantly reduce the rectifier losses, with superior forward-voltage and reverse-recovery characteristics that enable increased power density with high efficiency. The forward voltage is 50-100mV better than in comparable planar diodes, depending on current and temperature conditions. Simply changing to these devices can increase the efficiency by 0.5%.

There are 28 variants in the new family, with eight current ratings from 1A to 15A, multiple surface-mount packages, in industrial and automotive grades (more info).
