Introduction

The JANTX1N4955C is a single zener diode constructed in a typical three-pin package. It is used for many different applications, but its main purpose is to provide a regulated voltage to a circuit. The JANTX1N4955C has various ratings, including a maximum power dissipation of 1W, a working temperature range of -55°C to +150°C, a reverse voltage of 3.2V, and a forward voltage of 0.9V. It produces a stable Zener voltage of 5.5V. It also has an avalanche rating of 4.5V.

Application Fields

The most common application of the JANTX1N4955C is to provide a stable voltage source to a circuit. It is often used in voltage regulators and power supplies to regulate the voltage within a circuit. It is also used in audio devices to produce a more accurate, consistent sound. The JANTX1N4955C is also used for protection in circuits that would otherwise be vulnerable to voltage spikes or irregularities, such as computers and other electronic devices. Additionally, it is often used as an emergency power source, as it can provide up to 5.5 volts.

Working Principle

The JANTX1N4955C is essentially a voltage-regulated diode, which means that it operates on the principle of a Zener diode. In this type of diode, the reverse breakdown voltage is determined by the doping concentration of the semiconductor. The JANTX1N4955C is designed so that its reverse breakdown voltage is 5.5V. This means that when the voltage across the diode exceeds 5.5V, the diode will begin to conduct current in reverse, thus preventing any further voltage increase in the circuit. The diode will also remain in this state until the reverse current drops, which occurs when the voltage drops below 5.5V. Thus, the JANTX1N4955C serves as an excellent voltage regulator, maintaining a stable 5.5V output in the circuit, regardless of fluctuations in other parts of the circuit.

Conclusion

The JANTX1N4955C is a single zener diode constructed in a three-pin package. Its primary purpose is to regulate the voltage of a circuit, and it produces a stable 5.5V output in order to do this. Its applications include voltage regulation, audio devices and emergency power sources, as well as voltage protection for electronic circuits. It operates on the principle of a Zener diode, in which the reverse breakdown voltage is determined by the doping concentration. It is an excellent voltage regulator, allowing a circuit to remain at a stable output of 5.5V regardless of fluctuations in other parts of the circuit.
