10A SCHOTTKY BARRIER
RECTIFIER
DESCRIPTION
The UTC
MBR1645C
is a Schottky Barrier Rectifier with high
efficiency, low power dissipation and high current capacity. It can
be applied in high frequency, low voltage inverters, polarity
protection and free wheeling applications.
FEATURES
* High surge capability
* High efficiency, low power dissipation, high current capability, low
forward voltage drop
* Guardring for overvoltage protection
