Product details

A small Schottky for low-voltage rectification

The STMicroelectronics STPS0520M is a 500 mA Schottky rectifier rated for 20 V reverse voltage, housed in the tiny DO-216AA STmite surface-mount package. The 50 µA reverse leakage at 20 V is typical for a Schottky of this voltage class — fine for most power paths, though worth a second look if your circuit idles for long periods on a battery.

For a new design, do not plan around this part — pick an active Schottky in the same DO-216AA footprint.

Package and hand-solderability

The DO-216AA (STmite) is a small, two-terminal surface-mount package. With a bit of care and a fine-tipped iron, it is hand-solderable — the body is large enough to get a tweezer grip, and the pads are on opposite ends. No hidden thermal pad underneath, so rework is straightforward.

Frequently asked questions

What is the replacement for STPS0520M?

STMicroelectronics has not published an official successor order code for the STPS0520M. For a new design, select an active Schottky rectifier in the DO-216AA package with a 20 V reverse voltage and 500 mA current rating.
