TVS – Diodes

The Transient Voltage Suppressor (TVS) diodes, also known as Surge Protective diodes, are widely adopted in numerous applications and systems. The most famous device in this category is the MPLAD18KP100A diode, which is especially designed for surge and electrostatic discharge protection, and it is also specially used in aviation industries.A TVS diode is a three-terminal unidirectional or bidirectional device, designed with voltage-clamping protection capability that can be triggered at an overvoltage condition. During the avalanche breakdown, the TVS device will operate with extremely low leakage current and high stand-off voltage.The MPLAD18KP100A diode\'s application field includes voltage protection of low voltage circuits against transients, protection of data and signal lines, and powerful suppression of high altitude and airborne environments. It also provides protection for power channels and for reverse-polarity circuits. The major characteristics of the MPLAD18KP100A include a peak pulse power of 100W; a protection voltage of 18V; a leakage of 3uA; a capacitance of 7pF; two ESD levels of 8KV HBM, and 1700V contact discharge; RoHS Compliant, and a current limit of 2A.The working principle of a TVS protection diode is quite simple to comprehend. When a surge or transient voltage is applied across the two main pins of the diode, the voltage passes across the diode and is clamped at a specific value. The amount of current that passes through the diode is then limited, protecting the downstream components.The most common application for a TVS diode is in the protection of sensitive electronics from voltage transients caused by lightning or static discharge. When a transient occurs, the TVS diode will conduct the surge energy to ground. As a result, downstream equipment is protected from the voltage spike. As these spikes can cause significant damage to circuitry, installing TVS diodes near the main power input can be beneficial.The MPLAD18KP100A diode incorporates a wide range of features that make it ideal for many projects and applications. Its peak pulse power of 100W is higher than most standard TVS diodes, making it suitable for heavy duty applications. Its protection voltage of 18V allows it to be used in high voltage applications. The device\'s capacitance of 7pF ensures excellent transient suppression.TVS diodes are available in bi-directional and unidirectional configurations, with the latter featuring an integral suppression alloy wire that can further reduce voltage transients. The device\'s reverse leakage of 3uA makes it less susceptible to overheating and ensures reliable operation. The 8KV HBM and 1700V contact discharge of the MPLAD18KP100A makes it suitable for a wide range of applications.In conclusion, the MPLAD18KP100A diode provides outstanding protection from overvoltage, transient, electrostatic discharge, and power surges. It is the perfect solution for protecting circuitry in a wide variety of applications, from aviation to computer systems. Its features make it ideal for use in high voltage and heavy duty applications, as well as in transitioning between digital and analogue systems. Therefore, it serves as an ideal choice for protecting sensitive electronic systems from voltage transients and power surges.
