Transient Voltage Suppressors (TVSs) are a type of diode designed to protect sensitive electronic circuits from transients that could otherwise damage or destroy them. The MXRT100KP85AE3 is a unidirectional silicon avalanche diode specifically designed for electrostatic discharge (ESD) protection. It is rated for a 100V maximum peak pulse voltage, with a 85A surge current capability, and a 3ns maximum response time. In this article, we\'ll discuss the application field and working principle of the MXRT100KP85AE3.

Application Field

The MXRT100KP85AE3 is mostly used in high-speed Automotive, industrial, consumer, and telecommunications applications. It is suitable for protecting delicate, low-voltage circuits, such as microcontrollers, from high-voltage spikes and surges caused by electrostatic discharges, or feedback from high-energy load switching. The 3ns response time makes it especially useful in applications where high-frequency noise needs to be suppressed quickly. The 100V maximum peak voltage and 85A surge current capability also make it ideal for protecting components in high-power microcontroller applications.

Working Principle

The MXRT100KP85AE3 works by using a Zener voltage combined with a high-energy avalanche breakdown to clamp transients quickly and safely. In the off state, the diode acts as an open circuit, allowing no current to pass. When an external surge voltage exceeds the Zener voltage, the diode transitions from the off state to the on state. This transition is where the avalanche breakdown takes place, allowing current to pass through the diode quickly. The Zener voltage is also instrumental in clamping the transient voltage, since it is the point at which the avalanche breakdown occurs. This combination of high-energy breakdown and Zener voltage clamping is what allows the MXRT100KP85AE3 to quickly and safely protect delicate electronic circuits.

Conclusion

The MXRT100KP85AE3 is a specialized unidirectional silicon avalanche diode designed for ESD protection. Its fast 3ns response time, 100V maximum peak voltage, and 85A surge current capability make it well suited for use in a variety of high-speed automotive, industrial, consumer, and telecommunications applications. The diode works by using a Zener voltage combined with a high-energy avalanche breakdown to clamp transients quickly and safely. Overall, the MXRT100KP85AE3 is a reliable and durable transient protection solution that can help protect delicate electronic circuits from overvoltage transients.
