This document describes the features and characteristics of the STPS20L45CF/CW/CT/CFP/CG product, including low forward voltage drop, low switching losses, and insulated package. These products are designed for high frequency switched mode power supplies and DC to DC converters, and are intended for use in low voltage, high frequency inverters, free-wheeling, and polarity protection applications.
The STPS20L45 series are dual‑center‑tap Schottky rectifiers designed for high‑frequency switched‑mode power supplies, DC‑DC converters and low‑voltage inverters. They offer low forward voltage drop and low switching losses, making them suitable for free‑wheeling and polarity‑protection applications.
The handbook provides detailed electrical ratings, thermal resistance values, mechanical dimensions for various package types (ISOWATT220AB, TO‑220FPAB, D°PAK, TO‑247), and ordering information. Graphs illustrate forward voltage, leakage current, avalanche power derating and thermal impedance characteristics.
