The maximum output current this semiconductor device can handle is 100mA. It comes primarily in a TO-92 or advanced TO-226 package. Due to this biasing current, 2N3904 goes to the saturation state and the LED turns ON. This article describes the BC547 NPN transistor, its pinout, equivalents and operating principles, and its application in various electronic devices. When the switch is closed, the base of the transistor is biased, and current flows to the base of the transistor. Use APKPure App Get Electronic Component Pinouts old version APK for Android Download About Electronic Component Pinouts English More than 80000 electronic pinouts: Chips, Transistors, Diodes and more This application provides an offline database with more than 80000 electronic component pinouts. Due to this, 2N3904 remains in the cut-off state and the LED does not glow. And no current flows to the base of the transistor. Trojan horse (Trojan) Software that the user downloads or installs for a legitimate purpose that, without their. When the switch is open, the base of the transistor is not biased. The required resistor value can be easily calculated using Ohm’s law. Transistors PNP Silicon Features PbFree Packages are Available MAXIMUM RATINGS Rating Symbol Value Unit Collector Emitter Voltage VCEO 40 Vdc Collector Base Voltage VCBO 40 Vdc Emitter Base Voltage VEBO 5. Proper biasing of the base ensures adequate base current to turn ON the transistor.Ī resistor of 220 Ohm is connected between the load(LED) and the collector terminal to protect the LED from overcurrent. The base of the transistor is biased using a 10 K Ohm resistor(R3) in parallel to the 1 K Ohm resistor(R2) plus base-emitter junction resistance(in series). The complete circuit is powered via a 5 V supply. The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistor is a semiconductor device that is widely used for switching purposes and for the. In the circuit diagram given above, 2N3904 is used as a switch to turn ON/OFF an LED connected at the collector terminal.
