Product details

100 V, 2 A — the automotive Schottky that handles the heat

The STPS2H100ZFY is an automotive-grade Schottky rectifier rated for 100 V reverse and 2 A average forward current, housed in a SOD-123F surface-mount package.

Leakage and forward drop — the thermal trade-off

Reverse leakage is specified at 1 µA at 100 V — a tight figure that limits standby power loss in always-powered modules like ECU keep-alive supplies.

The part carries ROHS3 compliance and is built on the ECOPACK®2 platform, so it meets current environmental directives without a waiver. For a production BOM line, this means you can qualify it for new designs and stock reels without worrying about a last-time-buy window closing.

Frequently asked questions

Does STPS2H100ZFY replace STPS2H100U?

The STPS2H100ZFY and STPS2H100U share the same base product number STPS2H100, indicating the same die and electrical ratings. The difference is the package — the ZFY suffix points to the SOD-123F surface-mount package, while the U suffix typically refers to a different package variant (often SMB). If your board footprint matches SOD-123F, the ZFY is a direct functional replacement; verify the pad layout before committing.
