Product details

15 V, 20 A Schottky — low forward drop for high-current rectification

The STPS20L15D is a Schottky barrier rectifier from STMicroelectronics, rated for a maximum reverse voltage of 15 V and an average forward current of 20 A. The junction temperature ceiling is 125 °C, so the thermal path through the TO-220AC tab to a heatsink governs the real-world current derating.

Obsolete — no official successor listed

No direct replacement order code appears on the official record, so a new-design BOM should not rely on this part. The TO-220AC footprint is common across many 20 A Schottky diodes, so a parametric search for a 15 V, 20 A Schottky in TO-220AC will yield several active alternatives from ST and other manufacturers.

Through-hole TO-220AC — mounting and thermal note

The STPS20L15D comes in a TO-220-2 package (ST's TO-220AC variant), with through-hole leads for board mounting. The package ships in Tube form, which is typical for through-hole power devices.

Frequently asked questions

Where can I buy STPS20L15D available via RFQ confirmation?

The STPS20L15D is obsolete and not in active factory production.

What is a suitable replacement for STPS20L15D?

No official successor is listed by STMicroelectronics. A replacement must be selected by matching the key ratings: 15 V reverse voltage, 20 A average forward current, Schottky technology, and TO-220AC package. Several active Schottky diodes from ST and other manufacturers meet these parameters.
