1000 V, 30 A, 100 ns — the automotive fast-recovery diode for high-voltage switching
Switching loss and thermal budget
The 100 ns trr is specified at typical test conditions for fast-recovery diodes — this recovery time keeps turn-off losses manageable in hard-switched topologies like PFC boost stages and output rectifiers in LLC converters. At 30 A forward current the forward voltage drop is 2 V max, so conduction loss at full load is 60 W; the DO-247 package with its large copper tab must be heatsunk to keep junction temperature below the 175°C absolute maximum.

Package and mounting — DO-247 through-hole
The DO-247-2 package with straight leads is a through-hole package designed for high-current rectification. The large copper tab provides a low thermal resistance path to the heatsink — the mounting hole pattern matches standard TO-247 heatsink clips. The through-hole leads handle the 30 A continuous current without the trace-width constraints of a surface-mount package.
