Working Principle

The working principle of SMZJ3793AHE3/5B is based on the Zener effect. When the reverse bias voltage is above the Zener voltage of the diode, the diode will become a reverse-biased diode. When the bias voltage increases further, the current flowing through the diode begins to increase exponentially due to the Zener effect. This current is the Zener current.When the Zener current is kept constant, the voltage across the diode remains constant, regardless of the applied bias voltage. This is known as the reverse break-down voltage of the diode. The reverse break-down voltage of SMZJ3793AHE3/5B is 37 volts.
