Overview
The STPSC20H12GY-TR is an ultra-high performance power Schottky diode manufactured by STMicroelectronics. This diode is built using a silicon carbide (SiC) substrate, which allows for a 1200 V rating and exceptional performance characteristics. The SiC material enables the design of a Schottky diode structure with negligible reverse recovery and minimal capacitive turn-off behavior, independent of temperature. This makes the STPSC20H12GY-TR particularly suited for applications requiring high efficiency and robustness.
