STPS0540Z Description

Short technical summary and product information.

The STPS0540Z is a Schottky rectifier diode from STMicroelectronics designed for low-voltage, high-frequency applications. It features a maximum reverse voltage of 40V and an average rectified current of 500mA.

 

With a typical forward voltage of 500mV at 500mA, the STPS0540Z offers low conduction losses suitable for switching power supplies and freewheeling diodes. Its fast recovery time (≤500ns) enables efficient operation at high frequencies.

 

The diode is housed in a compact SOD-123 surface-mount package, making it ideal for space-constrained designs. The operating junction temperature range extends up to 150°C.
