SCHOTTKY DIODE
0.5 Amp
IF(AV) = 0.5Amp
VR = 40V
Description/ Features
Major Ratings and Characteristics
Characteristics
This Schottky diode is ideally suited for low voltage, high
frequency operation, as freewheeling and polarity protection.
Small size of the package allows proper use in application
where compact size is critical, fitting also the GSM and
PCMCIA requirement.
