Product details

80 A per leg, 45 V blocking — dual Schottky in an ISOTOP bolt-down package

Each diode is rated for an average rectified current of 80 A with a forward voltage drop of 690 mV at that current.

ISOTOP chassis mount — thermal interface is the whole point

The ISOTOP package is a large-area bolt-down module, not a PCB solder part. Mounting requires a heatsink with a flat surface and proper thermal interface material — the package base is the primary heat path.

The base product number STPS16045 is still in the active portfolio, so the usual distribution channel applies. No last-time-buy window to track, no forced alternate qualification on the horizon.

Frequently asked questions

Does the STPS16045TV have any known compatibility issues with 48V systems?

The maximum reverse voltage rating is 45 V. In a nominal 48 V system the bus can sit at 48 V steady-state and spike higher during transients. This part has no margin for a 48 V rail — it is designed for 24 V or lower-voltage buses where the peak reverse stays under 45 V.
