The company offers a comprehensive portfolio of energy efficient power and signal management, logic, discrete and custom solutions to help design engineers solve their unique design challenges in automotive, communications, computing, consumer, industrial, LED lighting, medical, military/aerospace and power supply applications. ON Semiconductor is driving energy efficient innovations, empowering customers to reduce global energy use. The way of controlling power motor via simple push button realizes the use 2N3055 as a switching device and in the same way we can use 2N3055 in other transistor circuits. With transistor going to high resistance state in OFF mode, the collector current also becomes zero bringing motor to stop. This motor will keep rotating until there will be base current.Īfter a certain time when the button is released the base current becomes zero and the transistor gets turned OFF. Having transistor acting as short circuit in ON state there will be collector current which flows through motor making it rotate. With this closed loop a current flows through base of transistor and with base current flow the transistor gets turned ON. When the button is pressed at certain time, the voltage V2 forms a closed loop with base-emitter of transistor as can be seen in circuit diagram. With no base current the transistor acts as open circuit and the entire supply voltage V1 will appears across it. Under initial conditions the button will be open and no current flows through the base of transistor. The 100Ω resistor is provided for limiting the current through base. The trigger source and power source must share a common ground for the circuit to work. Here we are going to use 2N3055 as a simple switching device to drive a motor and is in common emitter configuration.Īs show in circuit we are using a motor as the load and the gate signal for turning ON the transistor is provided by 5V source with button being the triggering device. Collector−Emitter Saturation Voltage − VCE(sat) = 1.1 Vdc (Max) IC = 4 AdcĪs mentioned earlier the 2N3055 can be used for any NPN transistor applications but for understanding the functioning of device let us consider a simple application circuit as shown below. Details, datasheet, quote on part number: 2N3055 Features, Applications Power dissipation 25☌ DC current gain hFE 4 A VCE ( Sat) 1.DC Current Gain − hFE = 20−70 IC = 4 Adc.Normally used as trigger to turn ON the transistor The pin configuration of 2N3055 is given below. Like any other transistor 2N3055 has three pins namely EMITTER, BASE and COLLECTOR. Using 2N3055 making an easy inverter circuit which can operate your led light, charge your mobile, fan, lcd, led, etc.
