Working Principle

The MMBZ5250B-7 is a PN junction diode with a Zener breakdown voltage. It operates in a reverse biased configuration. The application of a reverse bias reduces the width of the depletion region in the semiconductor junction. This decreases the voltage drop and will cause the diode to start conducting when the forward bias reaches a certain potential. This potential is known as the Zener breakdown voltage. In this range, the diode will start to conduct a controlled current and will regulate the voltage at the breakdown voltage.

The diode has a low forward voltage drop of 1V, which makes it highly suitable for over voltage protection or voltage regulation applications. The reverse current leakage has also been designed to be kept to minimum, which will help reduce power dissipation and improve temperature coefficient performance. It has also been designed to have a low capacitance, which helps reduce power consumption and reduce noise from the circuit. The device also exhibits a low temperature coefficient, allowing it to remain highly stable even in extreme temperatures.
