Product details

The forward voltage drop is 570 mV at 15 A, which keeps conduction losses manageable in a 15 A per-leg design. Reverse leakage at 45 V is 200 µA — typical for a 45 V Schottky at the hot junction, but worth derating if the ambient runs near the 200°C maximum junction temperature.

Any stock available now is from surplus or independent-distributor channels.

Package and mounting — through-hole I²PAK

Housed in a TO-262-3 (I²PAK) through-hole package, the STPS3045CR mounts into a standard TO-262 footprint with long leads. The common-cathode tab is the center pin — the two anodes are the outer leads. Through-hole assembly suits boards that need manual rework or higher thermal cycling robustness than an SMD package provides.

Frequently asked questions

Where can I buy STPS3045CR?

STPS3045CR is obsolete and no longer in factory production. Submit an RFQ for current availability and pricing; stock and price are confirmed at quote time.

What is the replacement for STPS3045CR?

For a drop-in common-cathode Schottky in the same I²PAK package, look at the STPS3045CW (TO-247) or STPS3045CT (TO-220) — but verify the package and thermal interface. A cross-reference search against 45 V, 15 A per-leg Schottky diodes in TO-262 is recommended for BOM continuity.
