Description
This device is part of ST's second generation of
600 V tandem diodes. It has ultralow switchinglosses with a minimized Q
RR
that makes it perfect for use in circuits working in hard-switching mode.
In particular the V
F
/Q
RR
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.
