Product details

Automotive Schottky — 100 V, 2 A, 790 mV Vf

The STPS2H100AF is an automotive-grade Schottky rectifier from STMicroelectronics, rated for 100 V reverse voltage and 2 A average forward current. Its forward voltage drop is 790 mV maximum at 2 A.

AEC-Q101 qualification gates the application

AEC-Q101 qualification is the line between this part and a commercial Schottky.

Reverse leakage at 100 V — 1 µA typ

Reverse leakage is specified at 1 µA at 100 V. For a 100 V Schottky, this keeps standby dissipation low in always-powered automotive modules.

SMAflat package — footprint and reflow

The SMAflat package is a low-profile surface-mount variant of the standard SMA footprint. The flat leads reduce the package height.

For production programs that run several years, this part does not introduce obsolescence risk at the diode level.

Frequently asked questions

Is STPS2H100AF AEC-Q101 qualified?

Yes, the STPS2H100AF is AEC-Q101 qualified, which is the automotive stress-test qualification for discrete semiconductors. It is suitable for under-hood and chassis-domain applications.
