3DD127D NPN TRANSISTOR 400V 2.5A 50W TO-126F

The 3DD127D NPN Power Transistor is a silicon NPN power switching transistor designed for power switching and electronic control applications. It provides a maximum collector-emitter voltage of 400V, collector-base voltage of 700V, and continuous collector current of 2.5A. The device is designed using a planar process with a voltage-dividing ring termination structure and minority-carrier lifetime control technology to provide high-voltage capability and suitable switching performance.

Features:
  • Silicon NPN power switching transistor.
  • 400V collector-emitter voltage.
  • 700V collector-base voltage.
  • 9V emitter-base voltage.
  • 2.5A continuous collector current.
  • 5A collector pulse current for tp<5ms.
