Sales Briefcase
  • This device is part of ST's second generation of 600 V tandem diodes. It has ultralow switching-losses with a minimized QRR(6.5 nC) that makes it perfect for use in circuits working in hard-switching mode. In particular the VF/QRRtrade-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.

    Key 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
