What Is JAN2N1482?

JAN2N1482 is an NPN Silicon Planar Darlington Transistor. It is a two element, single-package, medium-power transistor produced by Dell Technologies. This transistor has been produced since the 1940s and has been used in a variety of designs, from military and aerospace projects to consumer electronics.

Application Field and Working Principle of JAN2N1482

The JAN2N1482 can be used in a variety of applications such as amplifying, switching, and signal processing. This transistor is typically used in power amplifiers, switch mode power supplies, signal conditioners, high-performance voltage regulators, motor controls and high-speed logic circuits.The JAN2N1482 transistor has two main terminals, the base and the emitter, as well as two other terminals, the collector and the base-emitter junction. The base-emitter junction is the region between the collector and the base and it is the active region where current flows when the device is activated.To understand the working principle of a JAN2N1482, let us consider the following diagram.When a voltage is applied to the base terminal, the base current (IB) flows through the resistor and the junction diode. This current causes the base-emitter junction to become forward biased, which subsequently allows the collector current (IC) to flow. The IC flows from the collector through the resistor, and into the emitter.The current gain of the JAN2N1482 is determined by the ratio of the collector current to the base current and is usually less than 10. This means that the transistor can be used as an amplifier or switch. When it is activated, the transistor can be used to regulate the output current, allowing it to be used in a power supply or as a PWM controller.

Conclusion

The JAN2N1482 is an NPN Silicon Planar Darlington Transistor which can be used in a variety of applications such as amplifying, switching, and signal processing. It is typically used in power amplifiers, switch mode power supplies, signal conditioners, high-performance voltage regulators, motor controls and high-speed logic circuits. The JAN2N1482 has two main terminals, the base and the emitter and two additional terminals, the collector and the base-emitter junction. The current gain of the transistor is determined by the ratio of the collector current to the base current and is usually less than ten.
