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
