Common-cathode fast recovery pair in TO-220-3
The 850 mV forward voltage drop at 8 A keeps conduction losses manageable, while the 150°C maximum junction temperature allows operation in thermally constrained environments such as enclosed power supplies and motor drives.
A 35 ns reverse recovery time places this diode in the fast-recovery class, suitable for switching frequencies up to several hundred kilohertz. In a continuous-conduction-mode boost or flyback converter, the trr directly sets the reverse-recovery charge that the MOSFET must absorb at turn-on; a 35 ns trr keeps that charge low enough to avoid excessive ringing or thermal stress in the active switch. The common-cathode pair lets you wire two diodes with a shared cathode connection, reducing PCB trace inductance in a centre-tapped secondary winding layout.
