MAPLAD 18KP8.5CA Application Field and Working Principle

TVS - Diodes are specialised forms of semiconductor devices, particularly designed to provide high voltage protection to make sure that further damage to a digital system is prevented. MAPLAD 18KP8.5CA is a type of TVS - Diodes manufactured by Matrix. It is a bi-directional high-energy TVS for overvoltage protection and delivers high speed protection into low impedance loads. In this article, we will discuss the application fields of MAPLAD 18KP8.5CA and its working principle.

Application Field:

MAPLAD 18KP8.5CA is widely used for providing an efficient protection across power supply rails, Ethernet ports & ports for computers and industrial systems. It is commonly used in telecommunication applications, networking equipment, data lines, mobile devices and medical equipment. MAPLAD 18KP8.5CA can be used for protectingEthernet ports, including two data lines (RX/TX). It can also be used for protecting data lines such as USB, RS232, RS485, coaxial and PS/2 ports. Furthermore, MAPLAD 18KP8.5CA can be used for protecting microprocessor power supply rails, such as 3.3, 5 and 12 volts providing protection against overvoltage transients on both power and data lines.

Working Principle:

MAPLAD 18KP8.5CA works by providing a fast-response protection against electrical overvoltage events. It engages when it reaches its breakdown voltage (VBR), limiting the voltage across the circuit to its peak power rating (P PK ). As soon as the voltage is lower than the breakdown, the protection is automatically set back and the TVS - Diode is ready to be used once again. MAPLAD 18KP8.5CA\'s response time is measured in nanoseconds, which allows it to protect the circuit quickly enough and without any issues. The design of the TVS - Diode is made by integrating a breakdown voltage into an ultra-low impedance reverse-biased P-N junction into an epoxy block package. This ensures that the protection is effective even in low-impedance loads. The MAPLAD 18KP8.5CA\'s threshold provides protection against high voltage transients from -45 to 22V. Its peak pulse dissipation and peakpower rating are 8,500W and 18W, respectively. It also hasa capacitance of 5,3pF per linein both directions.

Conclusion:

In conclusion, MAPLAD 18KP8.5CA is a type of TVS - Diodes designed to provide fast protection against overvoltage events. It has wide application fields, including telecommunication applications, networking equipment, data lines, mobile devices and medical equipment as well as for protecting microprocessor power supply rails. Working principle of MAPLAD 18KP8.5CA involves quickly engaging when it reaches its breakdown voltage (VBR) and limiting the voltage across the circuit to its peak power rating (P PK ). It has fast response time and it can be used in low-impedance loads.
