BD139-16 Description

Short technical summary and product information.

The BD139-16 is an NPN power transistor manufactured by ST, designed for applications requiring moderate power handling. It is housed in a TO-126 (SOT32) plastic package, suitable for through-hole mounting.

 

Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 80V and a continuous collector current (IC) of 1.5A. The device also offers a peak collector current (ICM) of 2A and a peak base current (IBM) of 1A. Its DC current gain (hFE) ranges from 63 to 250 at an IC of 150mA and VCE of 2V, with a typical transition frequency (fT) of 190MHz at 50mA and 5V.

 

Thermal performance is supported by a junction-to-mounting base thermal resistance of 10 K/W, allowing for efficient heat dissipation. The transistor is rated for a total power dissipation of 8W at a mounting base temperature of 70°C. Operating and storage temperatures range from -65°C to +150°C.

 

This transistor is commonly used in driver stages for hi-fi amplifiers and television circuits, leveraging its combination of current capability and voltage rating.
