TVS - Diodes

TVS (transient voltage suppressor) diodes are surge protection components used to protect electronic circuits and components from electrical transients which can damage or destroy sensitive components. The primary application of these parts is designed to protect against transient overvoltage events such as electrostatic discharge (ESD) or lightning surges. Typically, a TVS diode can absorb over 400 watts of peak power and many higher power devices can absorb up to 1000 watts.

MXPLAD15KP90AE3

The MXPLAD15KP90AE3 TVS diode is a unidirectional device with a maximum clamping voltage of 15.4V. This diode component is made up of two back-to-back ESD varistors (varistors are high-voltage resistor and capacitor combinations). The MXPLAD15KP90AE3’s output is designed to dissipate up to 125A of peak ESD (electrostatic discharge) current for devices rated up to 25V. This diode is made of a silicon based material designed to extend the working life of the device and minimize performance degradation. The MXPLAD15KP90AE3 also includes a thermal protection cutoff feature for over temperature/overcurrent protection.

Applications

The MXPLAD15KP90AE3 TVS diode is most often used in sensitive electronics and equipment that are susceptible to transient overvoltage surges, such as cell phones, digital cameras, and laptops. Its bi-directional protection and low-profile design makes it suitable for use in densely populated designs, including areas that have limited space. It is also commonly used in automotive, medical, and industrial equipment, or any other device that could be subjected to ESD or electrical transients that could damage or destroy the device.

Working Principle

The MXPLAD15KP90AE3 TVS diode works by clamping transient voltage surges to a safe level. When a surge passes through the diode, the high-voltage varistors and low-voltage resistors activate, creating a temporary short-circuit between the source and the load. This effectively clamps the surge to a safe level and protects the system from the damaging electrical transient. The two resistors also act as a temperature sensor, allowing the device to automatically cut off the output when it reaches a safe temperature. This thermal cutoff feature helps protect against overheating and flames.

Conclusion

The MXPLAD15KP90AE3 TVS diode is a fast-acting, unidirectional electronic protection device designed to protect sensitive electronics and equipment from damaging electrical transients. Its bi-directional protection and low-profile design makes it an ideal choice for use in today’s densely populated electronic designs. The MXPLAD15KP90AE3 is a robust, thermally stable device that can dissipate up to 125A of peak ESD current. Its simple operation, wide operating voltage, and thermal cutoff feature make the MXPLAD15KP90AE3 a perfect choice for use in home, automotive, medical, industrial, and consumer electronics.
