Description

STPS2L60

Power Schottky rectifier

DO-41

STPS2L60

Axial and surface mount power Schottky rectifiers suited to switched mode power supplies and high frequency DC to DC converters.

Packaged in SMA, DO-41 and SMB flat this device is especially intended for use in low voltage, high frequency inverters and small battery chargers.
