Product details

45 V, 30 A Schottky — common cathode in TOP-3I

The STPS6045CPIRG is a dual-Schottky rectifier from STMicroelectronics, configured as a 1 Pair Common Cathode in the TOP-3 Insulated (TOP-3I) through-hole package.

STMicroelectronics lists the STPS6045CPIRG as obsolete.

Parametric fit for high-current rectification

The common-cathode pair is a natural fit for center-tap full-wave rectifiers and half-bridge topologies in switch-mode power supplies and DC-DC converters. The 45 V reverse voltage covers 24 V and 36 V rails with margin; the 30 A per-diode rating supports output stages up to about 60 A total when the two diodes are paralleled. Reverse leakage is 500 µA at 45 V — a figure that rises with junction temperature, so thermal management of the TOP-3I tab is critical above 100°C.

Frequently asked questions

Is STPS6045CPIRG obsolete?

Yes, STMicroelectronics has marked the STPS6045CPIRG as obsolete. There is no official successor listed, so replacements must be sourced through independent distribution or by selecting a functionally equivalent Schottky in the same package and rating class.

What is the replacement for STPS6045CPIRG?

No official replacement part number is recorded on the lifecycle entry for the STPS6045CPIRG. A functionally equivalent Schottky diode with a 45 V reverse voltage, 30 A average current per diode, common-cathode configuration, and TOP-3I package would be the closest match — but the exact pinout and thermal performance should be verified against the original datasheet before substitution.
