This dual diode Schottky rectifier is suited for high frequency switched mode power supplies.

Packaged in DPAK, TO-220AB, TO-220AB narrow leads and I²PAK, this device is intended to be used in notebook and LCD adaptors, desktop SMPS, providing in these applications a margin between the remaining voltages applied on the diode and the voltage capability of the diode.

Key Features
- High junction temperature capability
- Good trade-off between leakage current and forward voltage drop
- Low leakage current
- Avalanche capability specified
- High junction temperature
- ECOPACK^®2 compliant component for DPAK on demand
