Electric current will enter the Transistor via this pin. It is handy in controlling the biasing of Transistor (s).
Pin one is the emitter, and it's the terminal via which electric current drains out of the Transistor. The Transistor mainly comprises three pins. Additionally, biasing the Transistor requires a 5mA supply current to the base pin. Conversely, they stay closed (forward bias) when connecting an electrical signal to the base pin.Īlso, you can only connect loads of 200mA or equivalent collector voltage when using this Transistor. Thus, its collector and emitter pins remain in open mode when you hold the base pin to the ground. Read on.įig 1: Power Transistors and a Circuit Board 
Primarily, we'll dwell on its essential details, such as its pinout, features, and uses. We are interested in the 2n3904 Transistor and 2n3904 transistor datasheet in this article. You'll find multiple power transistors in electronics products, each suited to a different role.
