BDX34B Description

Short technical summary and product information.

The BDX34B is a complementary silicon PNP power Darlington transistor manufactured by STMicroelectronics. It is housed in a standard TO-220 plastic package, suitable for through-hole mounting.

 

This transistor is designed for power linear and switching applications. Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 100V and a maximum collector current (IC) of 10A. The device offers a maximum power dissipation (Ptot) of 70W at 25°C.

 

Operating temperature ranges from -65°C to 150°C, with a maximum junction temperature of 150°C. The thermal resistance from junction to case (Rthj-case) is 1.78°C/W.

 

Electrical specifications include a collector-emitter saturation voltage (VCE(sat)) of 2.5V at 3A and 6mA base current. The DC current gain (hFE) is a minimum of 750 at 3A and 3V collector-emitter voltage. A small signal current gain (hfe) of 100 is typical at 1A and 5V.
