2022年5月3日 · Introduction to the BD139 transistor, Pin diagram, How it Works, Specification, Features, Equivalent, Applications, and Download Datasheet

2018年10月18日 · BD139 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. BD139 has a gain value of 40 to 160, this value determines the amplification capacity of the transistor.
