Product details

Fast recovery diode for 200 V, 15 A rectification

The STTH1502DI from STMicroelectronics is a general-purpose fast recovery diode rated for 200 V reverse voltage and 15 A average rectified current.

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.

Frequently asked questions

What is the reverse recovery time of STTH1502DI?

The reverse recovery time (trr) is 36 ns at the rated forward current and reverse voltage conditions. This qualifies it as a fast recovery diode (≤500 ns, >200 mA).

Is STTH1502DI RoHS compliant?

Yes, the STTH1502DI is ROHS3 compliant, meeting the latest EU directive for restriction of hazardous substances in electronic equipment.
