ZMM5240B-13

The ZMM5240B-13 is a single zener diode with a low working voltage of 5.24V and a maximum power dissipation (PD) of 500mW. It is designed for applications requiring low reverse voltage and high reverse current ratings. The device is suitable for use in automotive, telecommunications, consumer electronics applications and other low reverse voltage applications.

The working principle of a single zener diode is based on the use of a negative temperature coefficient (NTC) polymer material inside the diode. This material is responsible for controlling the voltage and reverse current ratings of the diode. In reverse bias, the NTC material goes in its NTC state, meaning it conducts current more easily when the voltage across it increases. This allows the zener diode to block current up to a certain pre-set voltage, after which, it jumps to its “knee” state, where it conducts current in the reverse direction.

A single zener diode is used in many applications where low reverse voltage and high reverse current ratings are required. Its most common application is as a voltage regulator in devices with a large voltage range. It is also used in voltage multiplication circuits, constant current sources and RF applications. In automotive applications, it is often used for lighting, ignition and other DC circuits. In telecommunications, it is used for protection against accidental overvoltage.
