BD911 Description

Short technical summary and product information.

The BD911 is a high-power NPN bipolar junction transistor designed for general-purpose switching and linear amplification applications. Manufactured by STMicroelectronics, it features a maximum collector-emitter voltage (Vce) of 100V and a continuous collector current (Ic) rating of 15A, with a power dissipation (Pd) of up to 90W.

 

Key electrical characteristics include a minimum DC current gain (hFE) of 15 at Ic=5A and Vce=4V, a maximum collector-emitter saturation voltage (Vce(sat)) of 3V at Ib=2.5A and Ic=10A, and a typical transition frequency (fT) of 3MHz. The device is specified for operation up to a maximum junction temperature of 150°C.

 

The BD911 is offered in the industry-standard TO-220-3 package, designed for through-hole mounting. This package provides good thermal performance for the 90W power dissipation, making it suitable for power management circuits, motor drivers, and audio output stages.
