Working Principle

The JAN1N4129D-1 voltage regulator diode relies on its zener-breakdown voltage regulator to regulate the voltage. In this process, a zener diode is connected in reverse bias to a power supply. When the voltage across the diode increases above the zener voltage, a reverse current begins to flow, and the voltage across the diode remains relatively constant.

The zener diode lets current flow in both directions when forward biased. When reverse biased and the voltage reaches the breakdown voltage, current will flow and the voltage across the diode will remain relatively constant, as this current creates a voltage drop.

The voltage regulator diode can help protect against destructive voltage spikes by absorbing the excess energy. This helps to solve many problems, such as overloads, short circuits and power surges.

The JAN1N4129D-1 voltage regulator diode is a reliable component for voltage regulation and protection against voltage spikes, making it suitable for a range of applications.
