Its 55 ns reverse recovery time (trr) suits hard-switched power conversion stages. ## Switching speed and thermal headroom The 55 ns trr at 400 V reverse voltage and 60 A forward current keeps the reverse recovery charge low, which directly reduces turn-off losses in a hard-switched bridge leg. Forward voltage is 1.35 V maximum at 60 A, 25°C. At a 60 A average current the conduction loss is roughly 81 W per device; paired with the 175°C Tj max, the designer can push the junction closer to the limit before the thermal runaway risk appears, but the heatsink must still be sized for the total dissipation. The TO-247-3 through-hole package (supplier device package TO-247) is a standard three-lead power package with a large copper tab for heatsink mounting. The through-hole leads handle the 60 A current without additional bus bars in most layouts, and the isolated tab simplifies the heatsink interface — no insulating pad needed if the heatsink is grounded.","metaTitle":"STTH61W04SW Fast Recovery Diode, 400V 60A TO-247-3","metaDescription":"ST STTH61W04SW fast recovery diode: 400V Vr, 60A Io, 55ns trr, 1.35V Vf, 175°C Tj max.
