The Schottky Rectifier STPS340 is a power rectifier with a repetitive peak reverse voltage of 40V and an average forward current rating of 3A. It features low forward voltage drop, typically 0.52V at 125¬8C, and negligible switching losses, making it suitable for applications requiring efficient power conversion. The device is designed for high-frequency DC to DC converters and switch mode power supplies, and is packaged in a surface mount format (DO-214AB) for ease of integration into compact designs. It is avalanche rated and compliant with ECOPACK2 standards, indicating its suitability for environmentally conscious applications. The rectifier is ideal for use in telecom power supplies, set-top box power supplies, TV power supplies, and battery chargers.
