    These devices are high voltage fast-switching NPN power transistors. They are manufactured using high voltage multi epitaxial planar technology for high switching speeds and medium voltage capability.


    They use a cellular emitter structure with planar edge termination to enhance switching speeds while maintaining the wide RBSOA. The devices are designed for use in lighting applications and low cost switch-mode power supplies.

    Key features
    • High voltage capability
    • Low spread of dynamic parameters
    • Very high switching speed
    • Integrated antiparallel collector-emitter diode
