Product details

What this Schottky does on the board

The STMicroelectronics STPS3H100UF is a 100 V, 3 A Schottky rectifier in a surface-mount SMBflat package. Forward voltage drop is 840 mV at 3 A, with recovery under 500 ns.

Package and rework reality

This is the SMBflat variant with flat leads rather than the formed gull-wing of a standard SMB. The flat leads sit flush against the pad, giving a lower profile and more solder contact area.

The STPS3H100UF is an active, current-production part from STMicroelectronics, ROHS3 compliant.

Frequently asked questions

What is the reverse leakage current of STPS3H100UF?

Reverse leakage is 1 µA at the rated reverse voltage of 100 V.
