STPS140UY Description

Short technical summary and product information.

The STPS140UY is a Schottky barrier rectifier diode manufactured by STMicroelectronics. It is designed for high-efficiency power conversion applications requiring low forward voltage drop and fast switching.

 

With an average rectified current rating of 1 A and a maximum forward voltage of 650 mV at 2 A, this diode offers low conduction losses. The reverse recovery time is typically 500 ns, enabling high-frequency operation. The device operates over a junction temperature range of -40°C to 150°C.

 

The STPS140UY is housed in a DO-214AA (SMB) surface mount package, making it suitable for automated assembly processes. The SMB package provides a compact footprint for space-constrained designs.

 

Typical applications include high-frequency rectification, freewheeling diodes, and reverse polarity protection circuits.
