TVS (Transient Voltage Suppressor) Diodes are designed to protect sensitive electronics from voltage fluctuations or high power electrical events. The MXLPLAD7.5KP18A is a member of the particularly robust and reliable series of TVS products from Littelfuse. This article will provide an overview of the applications for which the MXLPLAD7.5KP18A is suitable, as well as an insight into its working principle.

Applications of the MXLPLAD7.5KP18A

The MXLPLAD7.5KP18A is ideal for a range of applications such as industrial equipment, automotive, consumer electronics, laptops and data storage systems. It offers protection from voltage fluctuations or high power electrical events by clipping transient waveforms to limits that won’t harm the relatively delicate components in the circuitry of these products. This series of TVS diode products are highly effective at absorbing high levels of surge current. It is capable of withstanding a surge current rating of ±10kA (8/20µs) at all terminal configurations.

The device is also tested and compliant with various UL standards, including certified RoHS2, UL1449 4th Edition, and EN-61373 shock and vibration testing. This ensures the MXLPLAD7.5KP18A is able to provide robust protection in a wide range of industrial, automotive, and consumer applications.

Working Principle of the MXLPLAD7.5KP18A

The working principle of a TVS diode is relatively simple. In its most basic form, it consists of a semiconductor diode connected in parallel with a load, or circuit. When an overvoltage reaches the diode, it will conduct a large current and very quickly dissipate the voltage away from the load. The device will remain in this conducting state until the overvoltage dissipates. As a result, it protects the load from the potentially damaging voltage.

The MXLPLAD7.5KP18A in particular is a uni-directional device with a unique Zener-like structure designed to protect against ESD and lightning-induced high surge currents. It is designed to withstand voltages up to 18V, and can provide up to 7.5A peak pulse current. It also has an impressive bi-directional power clamping capability, making it ideal for a wide range of applications.

Conclusion

The MXLPLAD7.5KP18A is a member of the robust and reliable TVS diode series from Littelfuse, and is ideal for backing up sensitive electronics against voltage fluctuations and high power electrical events. Its working principle is relatively simple, providing a uni-directional device with a Zener-like structure designed to protect against ESD and lightning-induced high surge currents. With its impressive peak pulse current and bi-directional power clamping capability, it is an ideal choice for a wide range of industrial, automotive, and consumer applications.
