1200 V SiC Schottky — why zero trr matters
The STPSC5H12B-TR1 is a 1200 V, 5 A silicon-carbide Schottky diode from STMicroelectronics, part of the ECOPACK® series. Its zero reverse recovery time (trr = 0 ns) eliminates the switching losses that plague ultrafast silicon diodes in hard-switched topologies — no recovery charge to clear, no ringing to snub.
Parametric fit for PFC and high-voltage rails
Rated for 1200 V reverse voltage and 5 A average forward current, with a forward voltage drop of 1.5 V at 5 A. Capacitance measures 450 pF at 0 V and 1 MHz, and reverse leakage is 30 µA at the full 1200 V blocking voltage — both typical for a 5 A SiC die in this voltage class.
STMicroelectronics lists the STPSC5H12B-TR1 as obsolete. Buyers should confirm date code and quantity requirements at quote time.
