Description/ Features
The 12CWQ10G surface mount, center tap, Schottky rectifier
series has been designed for applications requiring low for-
ward drop and small foot prints on PC board. Typical applica-
tions are in disk drives, switching power supplies, converters,
free-wheeling diodes, battery charging, and reverse battery
protection.
