STPS40L15CW is a center tap Schottky rectifier module from IRF company. It has ultra low forward voltage drop and high reliability, suitable for parallel switching power supplies, converters, reverse battery protection and redundant power subsystems.
The STPS40L15CW is a center‑tap Schottky rectifier module optimized for ultra‑low forward voltage drop, making it suitable for OR‑ing parallel power supplies, converters, reverse‑battery protection, and redundant power subsystems. It features a high‑temperature epoxy encapsulation and a guard ring for enhanced ruggedness.
Key electrical ratings include a maximum reverse voltage of 700 V, typical forward voltage drop of 0.41 V at 19 A (25 °C), and a maximum average forward current of 40 A. The device is supplied in a TO‑247AC (TO‑3P) package with a junction‑to‑case thermal resistance of 0.7 °C/W and is rated for operation up to 125 °C junction temperature. Ordering information, marking details, and mechanical dimensions are also provided.
