The MJE13009 transistor is a semiconductor device made of silicon material. It is an NPN transistor that is mainly used for switching and amplification purposes. The power dissipation of this transistor is 100 W, and the emitter-base voltage is 9 V; that is the amount of voltage needed to bias the device.
MJE13009 Transistor Pinout
The MJE13009 transistor carries three terminals known as
- Base
- Collector
- Emitter
All these three terminals are used for external connection with the electrical/electronics circuit. The figure given below shows the pinout diagram of MJE13009.
The pins carry different doping concentrations. The collector terminal is a lightly doped terminal, while the emitter terminal is a highly doped terminal compared to other terminals. Similarly, the base pin is 10 times more doped than the collector pin.
