BDX33C Description

Short technical summary and product information.

The BDX33C from STMicroelectronics is an NPN Darlington transistor designed for high-current switching applications. With a collector-emitter breakdown voltage of 100V and a collector current rating of 10A, it provides robust performance in power control circuits. The Darlington configuration offers a high DC current gain of 750 at 3A collector current and 3V collector-emitter voltage, minimizing base drive requirements.

 

The transistor features a saturation voltage of 2.5V max at 6mA base current and 3A collector current, ensuring efficient low-voltage operation. It dissipates up to 70W, making it suitable for demanding power stages. The device operates at junction temperatures up to 150°C, supporting reliable operation in thermally challenging environments.

 

The BDX33C is supplied in a TO-220-3 through-hole package, which simplifies mounting on standard PCBs and facilitates heat sinking. This NPN Darlington transistor is a practical choice for switching loads such as relays, solenoids, lamps, and resistive loads in industrial and consumer applications.
