FEATURES AND BENEFITS High junction temperature capability Avalanche rated Low leakage current Good trade-off between leakage current and
forward voltage drop
DESCRIPTIONSingle Schottky rectifier suited for high frequency
Switch Mode Power Supply.
Packaged in TO-220AC, this device is intended to
be used in notebook & 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.
