HERMETIC TO-257AA DUAL POWER SCHOTTKY
RECTIFIER
FEATURES
• Very Low Forward Voltage
• Low Recovery Charge
• Rugged Package Design, (JEDEC TO-257AA)
• High Efficiency For Low Voltage Supplies
• 45V Blocking @ Rated T
• 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.
