Fast recovery diode pair for 200 V, 5 A switching
Its 30 ns reverse recovery time (trr) suits high-frequency rectification, freewheeling, and snubber circuits where switching losses matter. The DPAK (TO-252) surface-mount package with exposed tab allows the designer to manage junction temperature through PCB copper area or a heatsink.
The 30 ns reverse recovery time places this diode in the fast-recovery class, not ultrafast. At 5 A forward current and 200 V blocking, the stored charge is low enough to keep turn-off losses manageable in a 50–100 kHz power stage. The 990 mV forward drop at 5 A is typical for a 200 V fast-recovery device; expect higher Vf at elevated junction temperature. The 50 µA reverse leakage at 200 V is a room-temperature maximum — leakage doubles roughly every 10°C above 25°C, so budget headroom in high-ambient designs.
Buyers should verify date code and traceability requirements with their quality team before purchasing a surplus lot.
The DPAK (TO-252) package has two leads plus a tab that is electrically common with the cathode. A heatsink or forced air may be needed if the combined dissipation exceeds the package's thermal impedance to ambient.
