DESCRIPTION / APPLICATIONS
IF(DC) per module at TC = 70 °C
120 A
Type
Modules - diode, FRED Pt®
Featuring a unique combination of low conduction and
switching losses, the VS-U5FX120FA120 is the right choice
for high frequency converters, both soft switched / resonant.
The semiconductor in the SOT-227 package is isolated from
the copper base plate, allowing for common heatsinks and
compact assemblies to be built.
Package
SOT-227
Circuit configuration
Two separate diodes,
parallel pin-out
These modules are specifically designed to improve
efficiency of PFC and output rectification stages of EV / HEV
battery charging stations, booster stage of solar inverters,
and UPS applications, these devices are perfectly matched
to operate with MOSFETs or high speed IGBTs.
