TDK-Lambda’s new 504 W AC to DC
PFH500F-28 is the company’s first product in
its new PFH power module series and its first
GaN-based solution. The module is designed
for use in harsh environment applications,
which require a high quality, high reliability
power system with the maximum power output
possible. Transphorm’s GaN FETs were selected
to meet those objectives.
TDK-Lambda’s redesigned standard power
module uses a bridgeless totem-pole power
factor correction topology to optimize
Transphorm’s TPH3206LDG FET in an 8×8
PQFN package. And, when compared to the
preceding PFE power module series, the
PFH500F-28 offers several Transphorm GaN-
driven advantages.
Ruggedized for harsh environments
5% efficiency increase
30% power density increaes (100 W/in

38% reduction in thermals
