5.0A SCHOTTKY BARRIER
RECTIFIER
DESCRIPTION
The UTC
SB540
is 5.0A schottky barrier rectifier. it uses UTC’s
advanced technology to provide customers with high current
capability and low forward voltage drop, etc.
The UTC
SB540
is suitable for free wheeling, low voltage and
polarity protection applications, etc.
FEATURES
* Metal to silicon rectifier, majority carrier conduction.
* For use in low voltage, high frequency inverters free wheeling,
and polarity protection applications.
* Low power loss, high efficiency.
* High current capability, low V
F
.
* High surge capacity.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. These ratings are limiting values above which the serviceability of any semiconductor device may be
impaired.
