  • The high quality design of this diode has produced a device with low leakage current, regularly reproducible characteristics and intrinsic ruggedness. These characteristics make it ideal for heavy duty applications that demand long term reliability.

    Such demanding applications include industrial power supplies, motor control, and similar mission-critical systems that require rectification and freewheeling. These diodes also fit into auxiliary functions such as snubber, bootstrap, and demagnetization applications.
    The improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device.

    Key Features

    • Ultrafast, soft recovery
    • Very low conduction and switching losses
    • High frequency and/or high pulsed current operation
    • High reverse voltage capability
    • High junction temperature
    • ECOPACK®2 compliant component for DPAK on demand
    • Insulated package: TO-220FPAC
      • Insulated voltage: 2000 VRMS sine
