A Zener diode is a special type of diode that is designed to conduct current in a reverse direction once the Zener breakdown voltage, also known as the Zener voltage, is reached. Zener diodes can also be used to regulate the voltage in a circuit, to insure that the output voltage is no greater than the Zener voltage. One such Zener diode is an JAN1N985CUR-1, a single Zener diode.

The JAN1N985CUR-1 is a single Zener diode that has a breakdown voltage of 5.6V, a maximum power dissipation of 400mW, a maximum reverse current of 10uA, a total capacitance of 10pF, and a forward Voltage drop of 1.3V. It has a maximum junction temperature of 150°C, and a thermal resistance junction to ambient of 50°C/W. It is rated for a maximum peak reverse voltage of 5.6V, and a maximum reverse leakage current of 10 uA at 5.6V.

The JAN1N985CUR-1 is used in circuits that require a stable voltage source or where voltage regulation is necessary. It is commonly used in power supplies and circuits that require a constant voltage, as the Zener diode can regulate the output current and voltage and ensure that the output voltage is no higher than the Zener voltage.

The working principle of the JAN1N985CUR-1 is fairly simple. In normal, forward biased operation, the diode acts as an ordinary PN junction diode. However, when the voltage across it exceeds the specified Zener breakdown voltage, the diode turns on and allows current to flow in a reverse direction. Once the reverse current has been established, the diode will act as a voltage regulator, and it will keep the output voltage from increasing above the Zener breakdown voltage.

The JAN1N985CUR-1 is an example of a single Zener diode and it has a variety of applications, most notably in power supplies and voltage regulation. It has a low forward voltage drop and a very low reverse leakage current. Once the specified Zener voltage is reached, the diode turns on and will act as a voltage regulator to stabilize the output voltage and keep it from increasing any further.
