JAN1N2989B Application Field and Working Principle

JAN1N2989B is a type of Zener Diode from Vishay Semiconductors which are used for regulating the flow of electric current in a circuit. Its primary purpose is to provide a precise voltage for voltage reference and protection of other components.

The JAN1N2989B is a single diode and has the following features:

• Average rectified current of 1.0 A
• Power Dissipation up to 1.5 watts
• Forward Voltage drop of 0.5 V
• Static Zener Voltage range 5.1 V to 200 V
• Temperature range from -65°C to +175°C

JAN1N2989B diodes are widely used in different application areas such as electronic circuits, telecommunications, aerospace and automotive. With a wide variety of features, this Zener diode can be suited to particular needs.

The working principle of a Zener diode is the same as any other diode: it allows current to flow in one direction while blocking it in the other. However, in the case of a Zener diode, it allows reverse current to flow backwards when a certain voltage (the Zener voltage) is reached. This is why Zener diodes are used for voltage regulation and protection in circuits.

A Zener diode is made up of P and N-type semiconductor materials that form a junction. This junction is said to break down when the Zener voltage is applied across the junction. This breakdown is known as “Zener breakdown”. The breakdown is caused by electrons which have enough energy to break through the depletion region of the junction and flow in the opposing direction. The breakdown voltage is determined by the doping levels in the materials forming the junction.

When the Zener diode is connected to an electric circuit, the Zener breakdown voltage is amplified. When the voltage of the external electric circuit surpasses the Zener voltage, the current flowing through the diode will be diverted to the electric circuit instead of the diode. This is known as the “Zener effect”.

When the external electric current decreases and the voltage across the diode rises again, the diode will then saturate and block current instead of allowing it to flow away from the diode. This is known as the “Reverse Breakdown”.

The JAN1N2989B Zener Diode is a single diode with a very wide Zener Voltage range of 5.1 V to 200 V. It is highly reliable in terms of durability and performance due its wide range of operating temperature -65°C to +175°C. This type of diode is designed for many applications including voltage stabilizing circuits, low-noise amplifiers, power supplies, rectifiers and many others.

In conclusion, the JAN1N2989B Zener Diode from Vishay Semiconductors is a high performance single diode with a wide range of features. It is highly reliable in terms of performance and durability and is used in a number of different application areas. It functions by allowing current to flow in one direction while blocking it in the other, and has a Zener breakdown voltage that allows it to act as a voltage stabilizing device.
