Its defining characteristic is zero reverse recovery time — the SiC Schottky barrier eliminates the stored-charge tail that forces silicon ultrafast diodes into a recovery loss spike at every switching edge. For a 1200 V device, that means the diode contributes essentially no switching loss in a hard-switched PFC, boost, or LLC stage, letting the designer push frequency higher or shrink the magnetics. ## 175°C junction — where it runs The 190 pF capacitance at 0 V and 1 MHz is typical for a 5 A SiC part; it does not ring excessively in a half-bridge node if the layout keeps the loop tight. ST lists the STPSC2H12B-TR1 as obsolete. ## Forward drop and leakage at 1200 V The maximum forward voltage is 1.5 V at 2 A — a typical figure for a 1200 V SiC Schottky at that current density. Reverse leakage is 12 µA at the full 1200 V rating, which is low enough that self-heating from leakage at high bus voltage is negligible in most designs. These numbers matter when you are doing the thermal derating: the 1.5 V drop at 2 A times duty cycle is the conduction loss; the zero recovery is the switching loss. Together they let you size the heatsink for a 5 A average load without the recovery spike margin that a silicon diode would demand.","metaTitle":"STPSC2H12B-TR1 SiC Schottky Diode, 1200V, 5A, Zero Recovery","metaDescription":"STPSC2H12B-TR1 1200V 5A SiC Schottky diode in DPAK.
