Product details

What this dual Schottky brings to the rail

The STPS30L40CG is a Schottky rectifier pair from STMicroelectronics, configured as a common cathode in a single D2PAK package.

STMicroelectronics lists the STPS30L40CG as obsolete.

Hand-solderable D2PAK — a maker-friendly note

The D2PAK (TO-263) is a surface-mount package with a large exposed tab. It is hand-solderable with a decent iron and some flux — pre-tin the pad, reflow the tab with a hot-air station or a big tip, then tack the leads. No tiny pitch to worry about, and the tab doubles as the thermal path, so a good solder joint there matters for keeping junction temperature under the 150°C max.

Frequently asked questions

What is the replacement for STPS30L40CG?

A functionally equivalent replacement would need to match the 40 V reverse voltage, 15 A per diode, common-cathode configuration, and D2PAK footprint. A parametric search across Schottky rectifiers in D2PAK with those ratings will turn up candidates from other manufacturers.
