55 ns reverse recovery — what it buys the automotive power stage
That trr places it in the fast-recovery class (≤500 ns, >200 mA), making it a fit for hard-switched rectifier stages in automotive DC-DC converters, boost PFC front-ends, and motor-drive freewheeling paths where recovery losses directly affect efficiency and junction temperature.
AEC-Q101 qualification — the gate for production automotive BOMs
Without this qualification the part cannot be placed in a production automotive BOM — it is the first check a component engineer runs.
600 V / 30 A — power-stage headroom and thermal budget
The 600 V reverse voltage provides margin for 400 V bus rectification and 48 V automotive systems with transient spikes. The 30 A average forward current is specified at the case temperature — the TO-220AC package with a proper heatsink can sustain that current in continuous conduction. Forward voltage is 2.95 V max at 30 A, so conduction loss at full load is about 88 W; the thermal design must keep the junction below 175°C.
