50V Repetitive Surge Voltage
Dual Schottky Rectifier In A Single Isolated Package
Available Non-Isolated (OM4201NT); Common Cathode Only
Available Screened To MIL-S-19500, TX, TXV And S Levels
DESCRIPTION
The OM4201ST has two Schottky barriers arranged in a common cathode
configuration and is ideally suited for a full wave output rectifier in low voltage
switching power supplies where small size and high reliablity are required. Common
anode and doubler configurations also available.
