Product details

Schottky pair for power rectification — 45 V, 2×15 A, common-cathode

The STPS3045CP is a dual Schottky rectifier from STMicroelectronics, configured as a 1-pair common-cathode diode. Forward voltage is specified at 570 mV maximum at 15 A, keeping conduction losses manageable in high-current power supplies and OR-ing circuits. The fast-recovery characteristic (≤500 ns at >200 mA) suits it for switching power supplies, freewheeling diodes, and polarity-protection applications where reverse-recovery losses matter. The 200°C maximum junction temperature provides thermal headroom for heatsink-mounted designs in industrial or telecom equipment.

Through-hole TO-218AC — heatsink-ready power package

Housed in a TO-218-3 / TO-218AC through-hole package (also designated SOT-93), the STPS3045CP is designed for bolted-down mounting to a heatsink. The three-lead common-cathode pinout is standard for dual-diode rectifier blocks, making it a drop-in fit for existing layouts that use this footprint.

Frequently asked questions

What is the replacement for STPS3045CP?

No official replacement part number is recorded for the STPS3045CP. For a functional equivalent in the same common-cathode Schottky family, a cross-reference search against 45 V, 2×15 A rated parts in TO-218AC or similar through-hole packages is needed. The STPS3045 base part number (without the CP suffix) may share the same die but verify package and configuration.
