HERMETIC JEDEC TO-254AA HIGH EFFICIENCY,
CENTER-TAP HIGH VOLTAGE RECTIFIER
FEATURES
• Soft Recovery Characteristics
• Hermetic Metal Package, JEDEC TO-254AA
• Very Low Forward Voltage
• Very High Reverse Voltage Capability
• Very Low Reverse Recovery Time
• Very Low Switching Losses
• Isolated Package
• Low Thermal Resistance
• Available Screened To MIL-S-19500, TX, TXV And S Levels
DESCRIPTION
This soft recovery rectifier is ideally suited as a free wheeling diode in converters and motor
control circuits, as well as a rectifier in SMPS. The package is designed for those
applications where a small size and a hermetically sealed package is desirable.
Center-Tap configuration.
