BD139-16 Description

Short technical summary and product information.

The BD139-16 is an NPN bipolar junction transistor manufactured by STMicroelectronics. It features a maximum collector-emitter voltage of 80V and a continuous collector current rating of 1.5A, making it suitable for general-purpose switching and amplification applications.

 

With a maximum power dissipation of 1.25W and a DC current gain (hFE) of at least 40 at 150mA collector current and 2V Vce, this transistor offers reliable performance in linear and switching circuits. The saturation voltage is typically 500mV at 50mA base current and 500mA collector current.

 

The device is available in a through-hole TO-225AA/TO-126-3 package, also known as SOT-32-3, and can operate at junction temperatures up to 150°C. It is RoHS3 compliant and has an MSL of 1 (unlimited).
