60 A fast recovery rectifier in DO-247
Its 90 ns reverse recovery time places it in the fast recovery class for switching power supplies, motor drives, and high-frequency rectification stages where recovery losses matter.
A 90 ns reverse recovery time at 60 A means this diode recovers fast enough for switching frequencies in the tens of kHz range without excessive turn-off losses. In a continuous-conduction-mode boost or PFC stage, that trr directly reduces the snubber requirement and the EMI signature compared to a standard recovery part. The 50 µA reverse leakage at 400 V is a room-temperature typical; expect it to rise with junction temperature, but the 175°C rating gives headroom for the thermal derating curve.
The base product number STTH6004 covers the family, and the W suffix denotes the DO-247 package variant.
