FEATURES AND BENEFITS
■ Ultrafast recovery allowing High Sustain
Frequency
■ Decrease charge evacuation time (t
clamp
) in the
inductance (see figures 1 and 2)
■ Minimize switching-on and total power losses
■ Increase luminuous efficiency and brightness
■ Soft and noise-free recovery
■ High surge capability
■ High junction temperature
DESCRIPTION
The STTH40P03S is an Ultrafast Recovery Power
Rectifier dedicated to energy recovery in PDP
application.
The key parameters of the D
diode for the
ERC
energy recovery cicuit have been optimized in
order to decrease power losses.
