A Zener diode, like any other diode, cuts off current in one direction while allowing it to pass in the other, with one major difference: when current starts to move in the forward direction, it has the ability to conduct current in the reverse direction when the voltage is greater than the breakdown voltage. The JAN1N968CUR-1 is a semiconductor component that belongs to the single Zener diode category, which is the most common type of Zener diode.

Overview

The JAN1N968CUR-1 is a power Zener diode, which is used in circuit designs that require steady and consistent current throughout the application. The component is a single diode, with an axial lead that makes it simple to install and use in any given installation.

The general ratings of the component are a continuous reverse voltage or VR of 9.1 V, an average forward current or IF of 200mA, a power dissipation or 2PD of 500mW, a junction temperature of 150°, an operating temperature of -65° to +175° and a storage temperature of -50° to +150°.

Application fields

The JAN1N968CUR-1 is designed to regulate the voltage in power supplies, and is also used in other electronic applications. It is especially useful for applications that need to keep a certain voltage level steady, such as in power supplies for automotive electronics, TVs, radios, video equipment and digital cameras.

The component is also used in LED lighting, replacement battery packs, battery chargers and various household electronics. Its wide operation temperature range makes it suitable for use in different sectors, including automotive and industrial circuits.

Working Principle

In a circuit, a Zener diode has two distinct operating modes: the forward conduction mode, and the steady reverse breakdown mode. When it blocks current in the circuit in the forward direction, it will start conducting when the voltage is increased beyond its breakdown voltage, which is determined by its manufacturer.

Once the diode starts to conduct in the reverse direction, the voltage across the diode will remain at a steady value, regardless of the amount of current that passes through. This is due to a feature called the avalanche effect, which occurs when the current stresses the atoms at the junction between the Zener diode and the other part of the circuit. This ensures that the voltage stays at a stable and consistent level.

Overall, the JAN1N968CUR-1 is a power Zener diode that can provide steady voltage regulation in any given application. Its low forward voltage and wide operating temperature range make it suitable for a variety of electronic devices.
