This combination of high blocking voltage and fast turn-off places it in the boost-PFC stage of switch-mode power supplies and in flyback converters where the diode must snap off cleanly before the next switching cycle begins. ## Forward voltage and leakage — the thermal budget Maximum forward voltage is 2 V at 12 A, which sets the conduction loss floor. Reverse leakage at rated blocking voltage is 10 µA — negligible at room temperature but it rises exponentially with junction temperature. The maximum junction temperature is 175 °C, so the designer must account for the Vf × If product plus the leakage power at high line in the heatsink calculation.","metaTitle":"STTH1210D Fast Recovery Diode, 1 kV, 12 A, 90 ns trr","metaDescription":"STTH1210D is a 1 kV, 12 A fast recovery diode with 90 ns trr in TO-220AC.
