Working Principle

MMBZ5267C-E3-08 relies on the principle of avalanche breakdown. This is a phenomenon that occurs when the reverse voltage applied across a lightly doped reverse-biased PN junction diode is increased to a certain threshold value and the diode conductivity increases suddenly, causing a sharp decrease in the reverse-bias voltage. The avalanche breakdown principle is used in zener diodes as they are highly doped, allowing to reduce the breakdown voltage. MMBZ5267C-E3-08 is designed to allow avalanche breakdown, acting as a clamping device over a wide range of voltage and current.
