This is information on a product in full production.
This device is part of ST's second generation of
600 V tandem diodes. It has ultralow switchinglosses with a minimized QRR (6 nC) that makes it
perfect for use in circuits working in hardswitching mode. In particular the VF/QRR trade-off
positions this device between standard ultrafast
diodes and silicon-carbide Schottky rectifiers in
terms of price/performance ratio.
The device offers a new positioning giving more
flexibility to power-circuit designers looking for
good performance while still respecting cost
constraints.
Featuring ST's Turbo 2 600 V technology, the
device is particularly suited as a boost diode in
continuous conduction mode power factor
correction circuits.
