2N3904 Transistor Pinout

2N3904 Transistor Pinout Diagram

The 2N3904 is an NPN type silicon transistor used in low power amplifiers, switching circuits, and so on. For example, to build a switching circuit, by inputting a small current through the base, the transistor will allow current to pass between the collector and emitter to light the LED.

Pin	Designation	Descriptive
1	E (Emitter)	Connect to ground (GND) or the negative terminal of the power supply
2	B (Base)	Control of transistor conduction
3	C (Collector)	Connect to the positive terminals of the load and power supply

Note: Be sure to identify the pins (emitter, base, collector) correctly to avoid damage to the device caused by misconnecting the pins.
