2N4401 NPN Transistor (10Pack)
2N4401 NPN Transistor (10Pack) 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. 2N4401has a gain value hfe of 500; this value determines the amplification capacity of the transistor.
Low power, small signal transistor with silicon planar epitaxial construction, designed for general purpose switching and amplifier applications.
2N4401 Pin Configuration
| Pin Number | Pin Name | Description |
| 1 | Emitter | Current Drains out through emitter, normally connected to ground |
| 2 | Base | Controls the biasing of transistor, Used to turn ON or OFF the transistor |
| 3 | Collector | Current flows in through collector, normally connected to load |
