A 36 ns reverse recovery time at 15 A forward current means the diode clears stored charge quickly, reducing turn-off losses and ringing in hard-switched converters. For a 100 kHz boost stage, the recovery charge per cycle stays low enough that the MOSFET or IGBT does not see an excessive current spike during diode turn-off. ## Package and mounting — TO-220AC insulated The TO-220AC insulated package (TO-220-2 with full encapsulation) eliminates the need for an insulating washer between the diode tab and the heatsink. The through-hole mounting suits point-to-point wiring on terminal blocks or PCB mounting with a single screw. The insulated backside simplifies assembly in metal-enclosed power supplies where creepage distance to ground is a concern. The base product number STTH1502 covers a family of voltage and package variants; the DI suffix specifically denotes the TO-220AC insulated version.","metaTitle":"STTH1502DI Diode, 200V 15A, 36ns trr, TO-220AC","metaDescription":"STTH1502DI general-purpose fast recovery diode, 200V 15A, 36ns trr, 1.1V Vf, TO-220AC insulated.
