BFX34

HIGH CURRENT GENERAL

PURPOSE TRANSISTOR

FEATURES

• SILICON EPITAXIAL NPN TRANSISTOR

• HIGH SPEED, LOW SATURATION SWITCH

• CECC SCREENING OPTIONS

DESCRIPTION:

The BFX34 is a silicon Epitaxial Planar NPN

transistor in a TO-39 case, intended for high

current applications.

Very low saturation voltage and high speed

at high current levels make it ideal for power

drivers, power amplifiers, switching power

supplies and relay drive inverters.
