                                                              High power NPN transistor

Features
   High power dissipation
   Low collector-emitter saturation voltage

Description
The device is a planar NPN transistor mounted in                         1
TO-3 metal case. It is intended for linear                                    2
amplifiers and inductive switching applications.
