STPS140U Description

Short technical summary and product information.

The STPS140U is a Schottky rectifier diode designed for high-efficiency power conversion. It offers a maximum reverse voltage of 40V and an average rectified current of 1A. The forward voltage is typically 550mV at 1A, enabling low conduction losses.

 

This diode is housed in a DO-214AA (SMB) surface-mount package, suitable for automated assembly. It supports fast recovery speeds of less than 500ns at currents above 200mA, making it ideal for switching power supplies and freewheeling applications.

 

The device operates at junction temperatures up to 150°C and is rated for surface-mount mounting. Its Schottky technology provides low forward voltage drop and fast switching, improving efficiency in DC-DC converters and polarity protection circuits.
