Diodes are elements used to draw and channel electrical current in circuits. Zener diodes are devices that regulate a certain voltage limit by reverse conduction with the help of an externally applied voltage. The 1N6351US is a single Zener Diode that is used to provide over and under voltage protection in a range of applications. This article will discuss the application field and the working principle of the 1N6351US.

Applications of the 1N6351US

The 1N6351US is a single Zener diode mainly used for voltage regulation and transient suppression. This diode features a maximum power dissipation of 1 watt and a junction capacitance variation from 5.8pF to 11pF. The 1N6351US provides protection for low voltage circuits, such as mobile phones, computer disks, radios, and automotive circuitry. It also has applications in power supplies, printed circuit boards, and other equipment subject to voltage fluctuations due to irregular mains power supply.

The 1N6351US has a breakdown voltage of 7.5V and a tolerance rating of +-5%. It also offers enhanced reverse voltage protection compared to its competitors. This allows the 1N6351US to be used in systems that require extra protection against reverse voltage surge. Additionally, this diode offers a high collecting current of 3mA, making it ideal for use in high power circuits.

Working Principle of 1N6351US

When the anode of the 1N6351US is at a higher voltage than the cathode, the diode starts conducting and current passes from the anode to the cathode. When the difference in the anode and cathode voltages exceeds the breakdown voltage of the diode, the current suddenly increases. This sudden increase in current is referred to as the Zener Breakdown. The 1N6351US features a Zener breakdown voltage of 7.5 V and a tolerance rating of +-5%.

When the forward current through the 1N6351US exceeds a certain limit, the device enters a state known as the Avalanche Breakdown. In this state, the breakdown voltage remains constant while the electrical current is increased. The avalanche breakdown helps protect the diode from an increase in forward current.

In addition to the Zener and Avalanche breakdowns, the 1N6351US also features a temperature coefficient of tolerance (TCt). When the temperature of the diode changes, the TCt ensures that the breakdown voltage remains constant. This helps ensure that the 1N6351US is able to provide consistent voltage regulation in the presence of temperature changes.

Conclusion
