Application field

The MMBZ5240B-7-F zener diode is most commonly used in consumer electronic applications such as computers, televisions, digital signs, and other consumer electronic equipment. It can also be used in industrial and automotive applications for voltage-regulating and overvoltage protection diversity.

Working principle

The MMBZ5240B-7-F diode works on the principle of the avalanche breakdown effect, wherein a current is passed through a diode in the reverse bias direction resulting in an increase in the electric field inside the semiconductor material. This electric field can get strong enough to cause electrons to detach from the atoms and start an avalanche of current. This leads to an abrupt increase in the reverse current, forming a potential barrier around the diode junction, which is known as the Zener voltage.

In operation, the MMBZ5240B-7-F is designed to break down when the applied reverse bias voltage exceeds the specified threshold voltage. When the reverse bias voltage exceeds the threshold voltage, the electric field inside the diode increases, resulting in an avalanche breakdown. This introduces a large amount of current known as the Zener current, which leads to a constant voltage drop across the diode. This voltage drop helps the device protect against overvoltages.

In addition to the overvoltage protection, the MMBZ5240B-7-F diode also provides electrostatic discharge (ESD) protection. The diode is designed to allow low levels of current to pass for protection against ESD voltages. As long as these voltages and currents do not exceed the rated maximum breakdown voltage and current, the device will remain safe and provide the required protection.
