## Description

The BDX64B is a silicon Darlington power transistor manufactured by Texas Instruments, designed for demanding power amplification and switching applications. It belongs to the BDX64 series, which includes complementary NPN transistors (BDX65 series).

This component features a TO-3 metal package, suitable for high power dissipation. Key electrical characteristics include a maximum Collector-Emitter Voltage (VCEO) of -100V and a continuous Collector Current (IC) of -12A. The device offers a high power dissipation rating of 117W at 25°C case temperature and a junction temperature range of -55°C to +200°C.

With a typical DC current gain (hFE) of 1000 at IC=-5A and a transition frequency (fT) of 7MHz, the BDX64B is well-suited for various power control circuits. The thermal resistance from junction to case is a low 1.5°C/W, facilitating efficient heat management.

Applications for the BDX64B include power supplies, audio amplifiers, and motor control circuits where high current gain and power handling capabilities are required. Its robust construction and electrical specifications make it a reliable choice for industrial and high-power electronic designs.
