Description
Because the 2N4401BU is an NPN transistor when the base pin is held at the ground, the collector and emitter are left open (reverse biased), and when a signal is applied to the base pin, they are closed (forward-biased). The gain value hfe of 2N4401BU is 500, which determines the transistor's amplification capacity. Because the Collector pin can only carry 800 milliamperes of current, we can't use this transistor to connect loads that draw more than 500 milliamperes. We must feed current to the base pin of a transistor to bias it, and this current (IB) should be limited to 5mA.
