  • 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

    • Insulated packages:\t\tTO-220Ins Electrical insulation = 2500 VRMSCapacitance = 7 pF\t\tTO-220FPAC Electrical insulation = 2500 VRMSCapacitance = 12 pF\t\t
    • Ultrafast, soft recovery
    • High frequency and/or high pulsed current operation
    • Very low conduction and switching losses
    • High junction temperature
    • High reverse voltage capability
