This document describes a dual center tap Schottky rectifier suitable for switchmode power supply and high frequency DC to DC converters. Packaged either in SOT-93 or TO-247, this device is intended for use in low voltage, high frequency inverters, free wheeling, and polarity protection applications. It features very small conduction losses, negligible switching losses, extremely fast switching, low thermal resistance, and specified avalanche capability.
The STPS4045CP/CW is a dual‑center‑tap Schottky rectifier designed for switch‑mode power supplies and high‑frequency DC‑to‑DC converters. It is offered in SOT‑93 and TO‑247 packages and is suitable for low‑voltage, high‑frequency inverter, free‑wheeling, and polarity‑protection applications.
The document lists key electrical ratings such as a 45 V repetitive peak reverse voltage and up to 20 A average forward current, along with thermal resistance values, forward voltage drop curves, and detailed mechanical dimensions for both package types. Recommended mounting torque values and cooling methods are also provided.
