Working Principle of MMBZ4703-E3-08

The MMBZ4703-E3-08 is a Zener diode, which has a “valley-shaped” forward-voltage / current curve. In normal forward bias application, current increases with applied voltage. Above the avalanche or Zener breakdown voltage, (6.2v) reverse current will flow until the diode voltage reaches a highly stable voltage in the reverse direction. This voltage remains almost constant no matter what the current flow through the diode is.

Almost zero power is dissipated in the Zener diode when voltage remains the same. This is why Zener diodes are so efficient compared to other types of diodes and make them very suitable for regulating, protecting and clapping applications. Due to the specific characteristics of their reverse voltage characteristic, they come in a large variety of breakdown voltages.
