STPS30SM80CFP

STPS30SM80CFP Description

The STPS30SM80CFP from STMicroelectronics is a high-performance Schottky diode array designed for fast-recovery rectification applications. Housed in a TO220FP through-hole package, it features 1 Pair Common Cathode configuration with an 80V maximum reverse voltage and 15A average rectified current per diode. Its Schottky technology ensures ultra-low forward voltage drop (790mV @ 15A) and minimal reverse leakage (40µA @ 80V), making it ideal for high-efficiency power conversion. With a fast recovery time (<500ns) and a 175°C maximum junction temperature, this diode array excels in demanding environments while complying with ROHS3 and REACH standards.
