Introduction:

JAN1N968DUR-1 is a type of single Zener diode commonly used for voltage regulation, voltage clamping, surge protection, and reverse polarity protection. It is an ideal voltage regulator for applications such as those on power supplies for cell phone chargers, LCD TVs, and other sensitive electronic devices.

Application Field:

The JAN1N968DUR-1 is designed to control the output voltage of an electronic device or circuit. It works by regulating the voltage between its two leads, one connected to the load and the other connected to a voltage source. It acts as a voltage-dependent resistor, so when the voltage between its two leads exceeds the Zener breakdown voltage, the diode will conduct current and limit the voltage on the load side to the specified breakdown voltage.

The JAN1N968DUR-1 is used mainly in power supply applications such as supplying regulated power to LCD TVs and cell phone chargers. It can handle up to 400V while dissipating up to 200mW of power; it also has a high surge peak power rating (up to 500mW). The JAN1N968DUR-1 can be used in voltage clamping applications such as protecting sensitive electronics from voltage spikes, as well as in reverse-polarity protection circuits.

Working Principle:

The JAN1N968DUR-1’s working principle is based on the Zener effect. The Zener effect occurs when a reverse-biased semiconductor pn junction reaches its breakdown voltage and a large reverse current starts to flow. This break down voltage (also called the Zener voltage) is dependent on the device’s junction temperature and junction area. The JAN1N968DUR-1 uses this Zener effect to regulate the voltage on the load side by allowing a reverse current to flow when the voltage between the two leads reaches the Zener temperature.

When the Zener breakdown voltage is reached, the diode will conduct current in a reverse direction and limit the voltage on the load side to the specified breakdown voltage. The device can be used as a voltage regulator by connecting it in series with the load, or as a voltage clamping device by connecting it in parallel with the load. It can also be used in reverse-polarity protection circuits.

Conclusion:

JAN1N968DUR-1 is a single Zener diode commonly used for voltage regulation, voltage clamping, surge protection, and reverse polarity protection. It is an ideal voltage regulator for applications such as those on power supplies for cell phone chargers, LCD TVs, and other sensitive electronic devices. The Zener effect is used to regulate the voltage on the load side, allowing it to act as a voltage regulator, a voltage clamping device, and a reverse-polarity protection circuit.
