2N3906_J61Z Application Field and Working Principle

The 2N3906_J61Z is a transistor used to switch and amplify electrical signals. It belongs to the family of bipolar junction transistors (BJT) which are divided into two categories: single transistors and complementary ones. The 2N3906_J61Z is a single transistor NPN type. It is used to switch ON and OFF electrical circuits, to amplify weak signals or to convert a low-level signal into a higher-level one.

Features

The 2N3906_J61Z features include an NPN type of construction, an IC Vce (Collector-Emitter Voltage) of 50V, a package of TO-92, an IC Vceo (Collector-Emitter Saturation Voltage) of 60V, and a max current of 200mA. It also features a Polarity Type of Reverse and a Frequency of 70MHz.

Applications

The 2N3906_J61Z transistor can be used in applications like amplifiers, switching circuits, input protection, inverter applications, and some classes of boost converters. It can also be used in the switch\'s last level of power supply, small automatic control systems, and low noise audio amplifiers.

Working Principle

The 2N3906_J61Z is a NPN transistor which consists of three layers; the Base, the Collector and the Emitter. It also consists of three connectors labeled as the base (B), collector (C), and emitter (E). The Base is a layer of negative charge and serves as the input signal. When a voltage is applied to the base, it causes a small current to flow that increases the current flowing between the collector and the emitter. This allows more current to flow from collector to emitter, so the transistor works like a switch. This allows the 2N3906_J61Z to act as an amplifier or switch in an electrical circuit.

Conclusion

The 2N3906_J61Z is a single transistor used to switch and amplify electrical signals, mainly used in amplifiers, switching circuits, input protection, inverter applications, and some classes of boost converters. Its features include an NPN type of construction, an IC Vce of 50V, a package of TO-92, an IC Vceo of 60V, and a max current of 200mA.
