![]() Here the voltage supply at the collector terminal is maximum as compared to the voltage at the base terminal. The 2N4401 NPN transistor is available in three configurations mainly CE (common-emitter), CB (common base), and CC (common collector). Operating temperature ranges from > -55 C Breakdown voltage from emitter to base (VBE) is 6V.Collector emitter voltage (VCE) is 40 V.When the collector current is 10mA, the gain of the high DC is 80.Includes three layers (N,P &N) & three terminals (E, B & C).The features and specifications of the 2N4401 NPN transistor include the following. Pin3 (Collector): This terminal is connected to load where the current supplies throughout this terminal.Pin2 (Base): This terminal is used to control the transistor biasing by turn ON/OFF the transistor.Pin1 (Emitter): This terminal is connected to GND normally and by using this terminal, the flow of current will drain out.This transistor includes three terminals where each terminal and its purpose are discussed below. The pin configuration of the 2N4401 NPN transistor includes the following. After that, the collector and base terminals will control the number of electrons. Here, the emitter terminal generates the electrons. Once a positive voltage is provided at the base terminal of this transistor, the transistor will be biased & allows the flow of current from the emitter terminal to the collector terminal. In this transistor, the base terminal is positive as compared to the emitter terminal.
