That 30 ns trr places it in the ultrafast class for a 200 V, 4 A part — the recovery charge is low enough to keep switching losses manageable in a 100–200 kHz PFC or DC-DC converter. The 1.05 V forward drop at 4 A is a reasonable trade-off for the speed; a slower diode would drop less but ring longer.
AEC-Q101 and the 175°C junction — under-hood ready
That combination is the baseline for automotive under-hood and transmission-mounted rectifier stages — the 175°C Tj max gives headroom for the hot soak conditions a standard 150°C part would derate into. The DPAK (TO-252-3) surface-mount package suits automated assembly on an IMS or FR4 board with a thermal pad pour.
