600 V tandem extra fast diode
Datasheet
−
production data
Features
• High voltage rectifier
• Tandem diodes in series
• Very low switching losses
• Insulated device with internal ceramic
• Equal thermal conditions for both 300 V diodes
• Static and dynamic equilibrium of internal diodes are warranted by design
• Insulated package:
– Capacitance: 7 pF
– Insulated voltage: 2500 V rms
Description
This device is part of ST's second generation of
600 V tandem diodes. It has ultralow switchinglosses with a minimized Q
RR
(6.5 nC) that makes it perfect for use in circuits working in hardswitching 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.
