Its 30 ns reverse recovery time makes it a fit for high-frequency switching circuits where recovery charge and switching losses matter. A 30 ns trr at 1 A forward current and 400 V reverse voltage suits continuous-conduction-mode PFC boost stages and flyback clamp circuits. The 1.5 V forward voltage drop at 1 A is typical for a 400 V planar fast-recovery die. ## 175°C junction — thermal headroom for tight enclosures Rated for a maximum junction temperature of 175°C, this diode can sit in a 100°C ambient with limited copper area on the SMA cathode tab and still stay inside its SOA. The 5 µA reverse leakage at 400 V and 25°C junction is a room-temperature floor; expect leakage to double every 10°C rise, so budget the thermal path accordingly.","metaTitle":"STTH1R04A 400V 1A Fast Recovery Diode, 30ns trr, SMA","metaDescription":"STTH1R04A is a 400V 1A fast recovery rectifier with 30ns trr in DO-214AC SMA.
