TVS (Transient Voltage Suppressor) Diodes are an essential electrical device used to protect the components and circuitry of a system from excessive transient voltages. The MXPLAD15KP110AE3 is one such diode specifically designed for applications in high-end industrial electronics and communications systems. This article will discuss its use cases, applications, and the working principle behind it.

Applications

The MXPLAD15KP110AE3 is designed to protect against high-end transients in industrial and communication systems. This diode has decent surge capability with a minimum 10.8 kA clamping voltage at 8/20 μs which makes it useful for high power applications. It is a suitable choice for short- or long-term ESD protection in electronic systems and networks with high frequency, high-speed protocols like Gigabit Ethernet (GbE) and Fibre Channel (FC).

The MXPLAD15KP110AE3 is also well-suited to high voltage portable device applications where it can be relied upon to protect against transients associated with user-induced errors like voltage transients in battery terminals, hot plugging/unplugging, or overcharging/undercharging. This diode also reduces ringing in electric motor speed controllers, thus improving overall system performance.

Working Principle

The MXPLAD15KP110AE3 operates on a diode-based suppression principle, whereby the diode is triggered when the voltage abruptly increases and becomes more positive than its rated peak pulse power. At this point, the diode conducts current and discharges the excess voltage instantaneously. The discharge is in the form of dissipated energy, which is often measured as Power Dissipation (PD).

When the voltage decreases, the diode turns off and reverts back to its non-conductive state, thus allowing the system to continue as normal. The ability of the diode to conduct and discharge the excess voltage instantaneously without suffering any major degradation or damage is known as "Transient Waveform Clamping".

Conclusion

The MXPLAD15KP110AE3 is a high-end application diode specifically designed for ESD protection in industrial and communication systems. Its surge capability and ability to reduce ringing makes it a suitable choice for high power and portable device applications. The diode operates on a diode-based suppression principle and is triggered when the voltage abruptly increases, whereupon it instantaneously discharges the excess voltage in the form of dissipated energy.
