Product details

It comes in a TO-220-3 through-hole package, intended for high-frequency switching power supplies, freewheeling diodes, and polarity protection where low forward drop and fast switching matter. The 780 mV maximum forward voltage at 7.5 A per diode is typical for a 80 V Schottky — it keeps conduction losses manageable in a 15 A total output leg (both diodes paralleled). The fast recovery spec of ≤ 500 ns at > 200 mA confirms it is suited for switching applications above line frequency, unlike slower standard rectifiers.

Frequently asked questions

What are the specifications of STPS15SM80CT?

The STPS15SM80CT is a Schottky rectifier with a common-cathode dual-diode configuration. It is rated for 80 V DC reverse voltage, 7.5 A average rectified current per diode, 780 mV maximum forward voltage at 7.5 A, and 20 µA reverse leakage at 80 V. It comes in a TO-220-3 through-hole package and operates up to 175 °C junction temperature.

What is the difference between STPS15SM80CT and STPS15SM80CG?

The STPS15SM80CT and STPS15SM80CG share the same die ratings (80 V, 7.5 A per diode, common-cathode) but differ in package. The CT suffix indicates a TO-220 through-hole package, while the CG suffix is a D²PAK surface-mount package. The choice depends on board assembly process and thermal management — TO-220 for through-hole or heatsink mounting, D²PAK for reflow soldering on a PCB.
