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.
別針 | Designation | Descriptive |
---|---|---|
1 | E(發射器) | Connect to ground (GND) or the negative terminal of the power supply |
2 | B(基礎) | Control of transistor conduction |
3 | C(收藏家) | 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.
