Its 100 ns reverse recovery time (trr) keeps switching losses low in hard-switched topologies like boost PFC stages and DC-DC converters in hybrid and electric vehicle power trains. ## AEC-Q101 qualification and 175 °C junction rating The 1.55 V forward voltage drop at 30 A sets the conduction loss — at full load that is about 46 W, so the TO-220AC tab must be heatsunk to keep Tj below the 175 °C ceiling.","metaTitle":"STTH30R04DY Automotive Fast Recovery Diode, 400V 30A","metaDescription":"STTH30R04DY automotive-grade fast recovery diode, 400V 30A, 100ns trr, AEC-Q101 qualified in TO-220AC.
