2N5349 is a very popular single transistor bipolar junction transistor (BJT). This device is commonly used in many applications, ranging from low-frequency, high-gain amplifiers to medium-power switching circuits. It is also ideal for applications where a reliable, low-cost, linear device is needed.

The 2N5349 single BJT is a bipolar transistor that is constructed with two N-type materials and one P-type material, located on the collector, base, and emitter, respectively. The collector and emitter form the output of the circuit, while the base of the transistor provides relatively low input impedance. The base is also the control terminal, where a small current or voltage is used to control the larger output current flowing through the collector-emitter junction.

In terms of specifications, the 2N5349 has a maximum collector-emitter voltage of 500V, with a breakdown voltage rating of 700V. In addition, the device has an hFE, or gain, of 300. This means that for every amplifier, the output current will be 300 times larger than the input current. This is useful when amplifying small signals that may not be powerful enough to directly drive the load.

The 2N5349 has a very handy feature that makes it suitable for a wide range of applications. The device has the ability to self-bias. This means that the base current can be adjusted without the need for an external resistor. This feature makes the device useable in circuits that require a wide range of operating currents. The saturation voltage of the device is also relatively low, which gives the 2N5349 excellent linearity characteristics.

The 2N5349 is commonly used as an amplifier as well as a switching device. In amplifier applications, the device amplifies small audio or electronic signals. The 2N5349 is often used in audio systems, where it is used to drive large speakers. In switching applications, the device is used to switch the output of a circuit on or off.

2N5349 BJT transistors are widely used in a variety of applications due to their reliable performance, low cost, and linear characteristics. Its self-biased feature makes it very convenient to use, and its wide range of operating currents makes it suitable for many different types of circuits. With its high gain and good linearity performance, the 2N5349 is an ideal choice for applications that require a reliable, linear transistor.
