It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. For more insights or questions on the working of this well-designed bipolar Transistor, talk to us.2N3904 is a semiconductor device used to amplify or switch electronic signals and electrical power. It also has a wide range of applications, as illustrated above. The 2n3904 Transistor is one of the essential BJTs - Bipolar Transistors. Primarily, this is because of the high base voltage emitter and emitter voltage collector. Helpful in controlling voltage logs of up to 40V.Essential in home appliances such as TVs.Standard in amplifier applications and amplifier modules, e.g., signal amplifier and audio amplifiers.Useful in driver modules such as in an LED Driver.Also, you can calculate the Transistor's DC gain as an amplifier using the formula:ĭC current gain = the collector current/ base current.īC639、BC549、2SC5200、2N2222 TO-18、2N3055、2N2222 TO-92、2N3906、BC636 The most common configuration you'll find in amplifier circuits is the common emitter type. Its adequate power, Voltage, and current amplification are in three main configurations in this mode. Thus, connecting a resistor in series with the base pin is imperative to prevent that.įor a transistor to function as an amplifier, you should operate it in the active region. Otherwise, It will destroy the Transistor. In this case, the maximum biasing current should be not greater than 5mA. You can control the bias mode by supplying the appropriate current to the base pin. Conversely, it will function as a closed switch when you set it in the reverse bias mode. Thus, the Transistor will act as an open switch during the forward bias mode. Operating this Transistor for switching implies using it in the saturation and cut-off regions. Also, the Base Emitter's typical Voltage at the cut-off region is approximately 600 mV.Īlso, note that measuring the collector-emitter Voltage and collector-base voltages at the Transistor's saturation point is possible.įig 4: Illustrating the Concept of Electric Switches The Transistor goes off on the removal of the base current.It has a maximum biasing current of 5mA and an ultimate Base- Emitter Voltage of 6V.Its continuous collector current will be 200mA, and the typical collector-Emitter Voltage is 40V.It is present in a To-92 Package and has a collector-Base Voltage of 60V.Also, features a maximum DC Current Gain (hFE) of 300 It belongs to the class of Bi-Polar NPN transistors.Electric current will enter the Transistor via this pin. It is handy in controlling the biasing of Transistor (s). Pin one is the emitter, and it's the terminal via which electric current drains out of the Transistor.The Transistor mainly comprises three pins. Additionally, biasing the Transistor requires a 5mA supply current to the base pin. Conversely, they stay closed (forward bias) when connecting an electrical signal to the base pin.Īlso, you can only connect loads of 200mA or equivalent collector voltage when using this Transistor. Thus, its collector and emitter pins remain in open mode when you hold the base pin to the ground. Read on.įig 1: Power Transistors and a Circuit Board Primarily, we'll dwell on its essential details, such as its pinout, features, and uses. We are interested in the 2n3904 Transistor and 2n3904 transistor datasheet in this article. You'll find multiple power transistors in electronics products, each suited to a different role.
