NTE2635

Silicon NPN Transistor

Horizontal Deflection w/Internal Damper Diode

Description:

The NTE2635 is an enhanced performance, new generation, high–voltage, high–speed switching

NPN transistor with an integrated damper diode in a full–pack envelope intended for use in horizontal

deflection circuits in color TV receivers. This device features exceptional tolerance to base drive and

collector current load variations resulting in a very low worst case dissipation.
