The ZMM5240B-7 also finds many uses in radio transmitter-receiver applications. Its high current capacity makes it suitable for use in a large variety of power conversion circuits and audio equipment. It can be used in digital circuit protection and in low impedance applications. It can also be used in power supplies and transformers, high current rectification, DC-DC converters, buck converters, active regulators, oscillators and other high frequency applications.

The working principle of the ZMM5240B-7 operates on the basic principle of Zener diode. When a voltage is applied across the diode, the current initially increases rapidly, as occurs with a diode. But when the voltage reaches a certain level, the breakdown, the current suddenly decreases and the voltage across the diode becomes nearly constant. This "breakdown voltage" of the ZMM5240B-7 is adjustable by varying the current through the diode.

The working of this diode in a power applications includes the reverse current blocking, over-voltage protection, ESD protection, battery-powered device protection and surge voltage protection. When the ZMM5240B-7 diode is used in a power system as a protection device, the current rating should be properly selected. The diode will protect the equipment from surges, transients and other voltage variations, providing reliable protection at a low cost.

The ZMM5240B-7 general purpose Silicon Planar Zener Diode is designed for use in applications that require reliable, high voltage protection and performance. Its wide range of applications makes it one of the most versatile diode products available and is ideal for use in medium to high frequency switching power supply applications. With their high stability, low leakage and other noise characteristics, these diodes are sure to provide reliable protection in a wide range of applications.
