The JAN1N6485US is a single Zener diode manufactured by Microsemi Corporation. It is a semiconductor device that uses a reverse-biased diode breakdown in a controlled manner. This diode is widely used for voltage regulation and clamping applications. It is designed to maintain a constant voltage across its two terminals, regardless of the changes in the load current.

The JAN1N6485US has an operating temperature range of -55°C to 125°C. This device has an absolute maximum voltage rating of 250V and a maximum power dissipation of 2W. The device has a maximum current of 1mA and a maximum current rating of 5mA. Its reverse recovery time is 0.1µs and a total capacitance of 1000 pF.

The JAN1N6485US is a single Zener diode with two pins which acts as an avalanche diode, able to conduct current in the reverse direction through the depletion region, allowing it to be used in various voltage regulation and clamping applications. The device is best suited for producing a stable and fixed voltage at its board level output. Due to its low power losses, it is suitable for use in low power devices.

The working principle of the JAN1N6485US single Zener diode is based on the avalanche breakdown mechanism. It is a thermal device, which uses a reverse biased p-n junction diode to maintain a constant and stable voltage at its output. The device works when a reverse bias is applied across the diode, which causes a slow breakdown in the depletion region, as the applied voltage increases. As a result, a “Zener” voltage or a reverse breakdown voltage is generated.

This reverse breakdown voltage is the basis for the voltage regulation characteristics of the single Zener diode. The breakdown voltage of the diode remains fairly constant regardless of the changes in the load current, helping to regulate and protect the applied circuitry. The diode can also be used as a clamp to protect circuits from overvoltage conditions.

The JAN1N6485US is a cost-effective and reliable single Zener diode solution, that can be used in a wide range of voltage regulation and overvoltage protection applications. It is used in circuits such as AC/DC adapters, power supplies, low power audio amplifiers, automotive systems, telecom systems, and many more. It is designed for general-purpose applications and can be used in either through-hole or surface-mount designs.
