BDX34C

Single Bipolar Transistors Overview

The BDX34C is a PNP silicon epitaxial-base power transistor in a monolithic Darlington configuration. It features a maximum collector current of 10 A and a collector-emitter sustaining voltage (VCEO(sus)) of 80 Vdc at 10 mA. The device offers a minimum DC current gain (hFE) of 750, with a typical value of 2500 at 4.0 A. Maximum power dissipation is 70 W, and the saturation voltage (VCE(sat)) is 2.5 Vdc max at 3.0 A. Operating temperature ranges from -65°C to +150°C. It is housed in a TO-220AB package.

Single Bipolar Transistors Feature Summary
