JAN1N4962D is an axial leaded, single copper-clad steel lead, glass-sealed Zener diode. It is designed for use in applications that require 4.7V Zener Voltage in medium power regulator applications. The device has a low temperature coefficient, low leakage, and high reliability.

Application Field

The JAN1N4962D Zener diode is designed for medium power voltage regulation, voltage clamping, and transient suppression. It is suitable for applications such as oscillator stabilization, voltage regulation, and efficient energy management.

It can be used in automotive systems, telecommunication systems, LED lighting, instrumentation, portable instrumentation, modules, modern sophisticated equipment, and other power controlling instruments.

Working Principle

JAN1N4962D Zener diodes are constructed with a heavily doped p-type material with a metallurgically deposited zinc lead and an p-pn overdriver. It acts as a two-variation reverse-body voltage regulating and current limiting device. When a Zener diode is connected in reverse direction (with the p-type layer connected to the negative terminal and the n-type layer to the positive terminal), it will conduct small current in the reverse direction until the voltage reaches a certain value; then the diode suddenly starts to conduct a much larger current. This is the junction voltage breakdown and this voltage essentially stays constant, even when the current is varied. This voltage is referred to as the Zener voltage and the device is called Zener diode.

The Zener voltage of JAN1N4962D is 4.7V. Hence, the terminal voltage of the secondary circuit is regulated to 4.7V, which is independent of the input voltage. The regulated output voltage is beneficial in applications such as voltage regulation, current limit sensing, and transient suppression. In addition, it also has a low temperature coefficient, low leakage, and high reliability.

JAN1N4962D Zener diode can also be used as impedance converters and active impedance change. This is done by varying the voltage across the Zener junction, either by applying a variable control current or applying a variable control voltage across it. The Zener diode in this case acts as an active variable impedance in the circuit.

In summary, JAN1N4962D is a single copper-clad steel lead, glass-sealed Zener diode designed for medium power voltage regulation and voltage clamping applications. It is used in automotive systems, telecommunication systems, LED lighting, instrumentation, portable instrumentation, modules, modern sophisticated equipment, and other power controlling instruments. The device has a low temperature coefficient, low leakage, and high reliability.
