STPS340S Description

Short technical summary and product information.

The STPS340S is a 40V, 3A Schottky rectifier diode from STMicroelectronics. It is housed in a surface mount SMC (DO-214AB) package, enabling compact PCB assembly.

 

The diode offers a low forward voltage drop of 630mV at 3A, minimizing conduction losses. Its average rectified current rating is 3A, and the maximum junction temperature is 150°C.

 

With fast recovery characteristics (≤500ns), the STPS340S is suitable for high-frequency switching circuits. The Schottky technology ensures low forward voltage and fast switching.

 

This component is designed for general-purpose rectification in power management and similar applications.
