MXPLAD30KP110CAE3 is an electrical component manufactured by Littelfuse. It is a Transient Voltage Suppressor (TVS) diode with an operating voltage of 30 kilovolts (kV). This device offers high surge capability up to 110 amps (A), and built-in surge protection for protection against lightning strikes, electrical surges, or overvoltage events. As a result, these TVS diodes provide robust protection for low-voltage electrical systems and components, as well as industrial high-voltage applications.

Applications

The MXPLAD30KP110CAE3 provides robust surge-protection and voltage-clamping capability. This TVS diode is primarily used in DC power systems including but not limited to: automotive and industrial (including renewable energy sources such as solar and wind), consumer, medical, telecom, aerospace, and military. It is also used in AC power systems such as home appliances, computers, home security systems, HVAC systems, and power tools.

This device is used to safeguard low-voltage power systems from transient overvoltage events, such as lightning strikes, electrical surges, malfunctioning equipment, or other voltage irregularities. Low-voltage applications protected by this device are not limited to consumer electronics, medical equipment, and automotive systems, but also include control systems, energy meters, smart energy grids, and renewable energy sources.

Working Principle

The MXPLAD30KP110CAE3 is a PN junction diode that works to control large amounts of electrical energy dissipation. It is designed with a low breakdown voltage, typically below 30kV at an operating current of 110A. When the incoming voltage exceeds this breakdown voltage, the diode will immediately conduct a flow of electrons to the load, effectively bypassing the overvoltage transient.

This principle is known as “clamping” or “maintaining” the surge voltage. The diode is then said to have “clamped” the voltage at its breakdown voltage, providing the necessary level of protection against excessive voltage transients. This diode is also designed to absorb excess energy, thereby dissipating it as heat to maintain a safe level of voltage at the circuit load. As a result, MXPLAD30KP110CAE3 can effectively protect circuit components from overvoltage transients, while also providing efficient circuit protection for a wide range of voltage ratings.

Conclusion

The MXPLAD30KP110CAE3 is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse. It is designed with a low breakdown voltage of 30kV and a surge capability of up to 110 amps (A) providing robust protection for a variety of low-voltage linear and switching power systems. Through the principles of “clamping” and “maintaining” the surge voltage, this device is well-suited for the protection of DC and AC power systems, automotive systems, medical equipment, consumer electronics, and more.
