MMBZ5246B-HE3-18 Working Principle

A Zener diode is a special type of diode designed to allow current to flow in a reverse direction beyond its Zener voltage (VZ). When the voltage across its anode and cathode is greater than or equal to its rated breakdown voltage, the diode begins to conduct in the reverse direction and the current flowing through it becomes constant. This allows it to serve as a voltage regulator, as the voltage across it remains constant regardless of the current through it.

The MMBZ5246B-HE3-18 Zener diode is electrically similar to a conventional PN junction diode except for its wider Zener voltage break Point (VBR). It makes use of the VBR phenomenon to regulate a certain voltage at its output terminal, regardless of any changes in current or load.

The MMBZ5246B-HE3-18 Zener diode is also called a “silicon avalanche diode” because of its strong avalanche ionization characteristic inside the diode. It features a high temperature operating capability and a low series resistance.
