HIGH POWER SILICON NPN TRANSISTORS
The 2N6253, 2N6254, and 2N6371 are silicon NPN transistors intended for a wide
variety of high-power applications. The construction of these devices renders them
highly resistant to second breakdown over a wide range of operating conditions.
These devices differ in maximum ratings for voltage and power dissipation. All are
supplied in JEDEC TO-3 hermetic stee l packages.
