Product details

Zero-reverse-recovery SiC Schottky for hard-switched power stages

The STMicroelectronics STPSC15H12DY is a 1200 V, 15 A Silicon Carbide Schottky diode in a TO-220-2 through-hole package.

1200 V blocking, 15 A average — derating headroom in a TO-220

Rated for 15 A average rectified current at a 1200 V DC reverse voltage, with a forward voltage drop of 1.5 V max at 15 A. The 1200pF capacitance at 0 V, 1 MHz is typical for a 15 A SiC die — the junction capacitance charges and discharges with negligible stored charge, so the switching energy is dominated by the output capacitance, not reverse recovery. The 90 µA reverse leakage at 1200 V is a room-temperature figure; SiC leakage rises with temperature, but stays well below silicon levels at the same junction temperature.

AEC-Q101 qualified — under-hood and chassis-domain ready

This part carries AEC-Q101 automotive qualification (series designation Automotive, AEC-Q101), covering the additional stress tests — high-temperature reverse bias, temperature cycling, and humidity — required for engine bay and transmission-mounted power electronics. The TO-220-2 package (supplier device package TO-220AC) is a standard through-hole footprint for heatsink-mounting in industrial and automotive power stages.

Lifecycle status is listed as Active. The base product number STPSC15 covers the 15 A SiC family across different package and qualification variants; the DY suffix specifically marks the AEC-Q101 TO-220-2 version.

Frequently asked questions

Is STPSC15H12DY automotive qualified?

Yes. The series designation is Automotive, AEC-Q101, covering the qualification tests required for automotive power electronics.

Can STPSC15H12DY replace STPSC15H12D?

The STPSC15H12D is the non-automotive variant of the same 15 A, 1200 V SiC Schottky die in the same TO-220-2 package. The DY suffix adds AEC-Q101 qualification; electrically the two parts are identical. If the BOM requires automotive-grade parts, the DY is the correct fit.

Is STPSC15H12DY suitable for high-frequency switching?

Yes. The zero reverse recovery time (trr = 0 ns) means there is no stored-charge turn-off loss, which is the dominant switching loss mechanism in silicon diodes above 50 kHz. The switching energy is limited by the junction capacitance (1200pF at 0 V) and the circuit parasitics, not reverse recovery.
