1,200 V SiC Schottky diode performs ultra-efficient switching

January 9, 2025

The STMicroelectronics STPSC20H12G2-TR uses a silicon carbide substrate to provide superior electrical and thermal characteristics, and can handle high voltage surges to give robust performance across a range of applications.

The STMicroelectronics STPSC20H12G2-TR is a 20 A, 1,200 V Schottky power diode fabricated on a silicon carbide (SiC) substrate which supports very fast and efficient switching. It is ideal for use in power-conversion functions such as: 

  • Power factor correction 
  • Dc-dc power converters 

 

The wide-bandgap SiC material permits the design of a Schottky diode structure which combines a low forward voltage, for reduced power loss and higher efficiency, with the robustness to handle a 1,200 V repetitive peak reverse voltage. The forward voltage drop is typically 1.5 V at a forward current of 20 A and a junction temperature of 25°C. 

 

Because of the Schottky construction, the diode draws little or no reverse-recovery current at turn-off, and ringing patterns are negligible. The negligible turn-off capacitance characteristic is stable across the operating-temperature range. 

 

The STPSC20H12G2-TR helps to boost performance in hard-switching applications. Its high forward surge capability ensures robust operation when exposed to transient voltages. 

 

The STPSC20H12G2-TR is supplied in a 10.0 mm x 15.3 mm D²PAK HV package. 

Features

  • 120 µA maximum reverse leakage current at a junction temperature of 25°C 
  • Switching behavior stable over operating-temperature range 
  • 129 nC total capacitive charge at a reverse voltage of 800 V 
  • 175°C maximum junction temperature 

Applications

  • EV charging stations 
  • Switch-mode power supplies 
  • Dc-dc converters
