Working Principle

The basic working principle of a Zener diode is the same as a regular diode, but the Zener diode will remain at a set voltage even if the input voltage rises. It only conducts when the input voltage rises above the Zener voltage, allowing current to flow and maintaining the output voltage at the predetermined level. The device is designed to prevent uncontrolled fluctuations in voltage as the input voltage rises, and typically has a Vz of 1.8-300V.

In the case of the 1N4751CE3/TR13, it is a low-power Zener diode, which reduces the power dissipation at a given Zener voltage. This allows the device to regulate lower input voltages, such as for motor efficiency control. The device is available with an 0.5–3.3V Zener voltage, offering a wide selection of Zener voltage options for a variety of applications.
