The JAN1N4462D is a Zener diode available in single package form by Fairchild Semiconductor. Zener diodes are used to regulate a voltage level or to provide protection against power surges. The JAN1N4462D is a silicon epitaxial planar diode designed for use in applications requiring protection from voltage levels over 6 volts, such as switching power supplies, AC/DC adaptors and telephone lines.

A characteristic feature of zener diodes is that they can be reverse biased, meaning they can be used when the voltage is applied in reverse to their normal operating direction. Zener diodes are ideal for protecting electric and electronic devices against transient or momentary voltage spikes. The JAN1N4462D is able to limit the maximum voltage to a safe level when used in this manner.

The JAN1N4462D diode is capable of effectively regulating voltage levels from 6.5 volts. It is a depletion type diode, meaning it will conduct current when all of the voltage is applied in reverse, which makes it a good choice for applications requiring very low on-state characteristics. Depending on the specific requirements of the application, the JAN1N4462D can be used to regulate anywhere from 6.5 to 40 volts.

The working principle of the JAN1N4462D is based on the Zener effect, which is the process whereby a diode experiences a decrease in voltage along its peak current region, known as the knee. The value of that decrease is called the Zener voltage, which is the maximum voltage that can be applied to the diode in order to achieve regulation. The JAN1N4462D has a 6.5 volt Zener voltage, meaning that the maximum voltage it will regulate is up to 6.5 volts.

The primary application of the JAN1N4462D Zener diode is voltage regulation, but it can also be used as an avalanche diode in certain circuits. Avalanche diodes are designed to break down near their peak current region and, when used in conjunction with an avalanche diode, the JAN1N4462D can provide protection against power surges.

The JAN1N4462D is also commonly used to provide a constant voltage source in linear power supplies. Its ability to regulate voltage with a very low on-state characteristics makes it an ideal choice in applications where power supply noise must be kept to a minimum. It is a cost-effective choice for DIY projects where a low-cost, dependable voltage source is required.

The JAN1N4462D has a number of advantages over traditional Zener diodes. It can easily be integrated into most circuits due to its low voltage requirements, it does not require a large heat sink for cooling, and it provides high-stability regulation of the applied voltage. In applications where reliability is key, the JAN1N4462D presents a viable option for high voltage protection.

The JAN1N4462D is a versatile, efficient silicon epitaxial planar diode designed for use in high voltage applications. Its ability to regulate voltage to 6.5 volts and its low on-state characteristics make it an ideal choice for applications requiring protection from transient spikes or a constant voltage source. It is an excellent choice for those in need of a reliable, low-cost voltage regulator.
