BD139 Medium power NPN transistor pack of 20pcs

BD139 functions as an NPN transistor. The gain range of this transistor is between 40 and 160. 1.5A is the utmost current capacity that could be achieved through the Collector pin. Increasing the current consumption below 1.5A enables this transistor to regulate larger loads (on/off). Additionally, its saturation voltage is rather low.

Package includes:-
