Transient Voltage Suppressors (TVS), also known as Transorb Diodes, are a critical component of many electronic designs. They are designed to protect against voltage spikes of high energies, like electrostatic discharges (ESD) or lightning-generated surges. The MXRT100KP260AE3 is a particular TVS component manufactured by IXYS, one of the leading power semiconductor suppliers in the world. In this article, we’ll look at the specifics of this component and explore its application fields and working principle.

Application Field

The MXRT100KP260AE3 is an integrated solution for protecting consumer electronics and other medium-power applications against ESD, lightning, and other surge-like transient events. It has an avalanche clamping voltage of 10V and a uni-directional breakdown voltage of 9.5V. This conforms to IEC 61000-4-2 (level 4) ESD standard, making it ideally suited for consumer electronics, such as laptop computers, mobile phones, tablets, and other handheld or home-appliances.

The component can also be used in other medium-power applications such as LED lighting, power supplies, automotive, avionics, and medical devices, as it has a low clamping voltage with a nominal minimum break down voltage of 10V. The part is available in a variety of package styles such as SOT-23, SMC, and DFN for very low-profile designs.

Working Principle

The MXRT100KP260AE3 is a single uni-directional device that operates by clamping the voltage to a pre-defined level. This means that when an ESD event or other transient surge is detected, the voltage that is applied across the TVS device is clamped to a certain level, thus preventing any damage to the devices being protected. This is done by the built-in Zener diode element, which acts as a voltage limiter.

When the transient voltage across the device exceeds a certain threshold, the PN junction diode built into the device starts to conduct, thus limiting the total voltage that is applied to the protected devices. As the voltage further increases, the current through the device increases accordingly, but the clamping voltage of the device remains constant. This ensures that neither the protected devices nor the TVS device itself will be damaged.

The MXRT100KP260AE3 also has a built-in discharge current protection feature. This prevents surges from over-loading the device and ensures the efficient protection of the connected devices. It also has a low capacitance, making it suitable for use in high-speed data circuits.

Conclusion

The MXRT100KP260AE3 is a low-cost yet effective integrated solution for protecting consumer electronics, LED lighting, power supplies, automotive, avionics, and medical devices against ESD, lightning, and other surge related events. It has a very low clamping voltage with a nominal minimum break down voltage of 10V, making it ideally suited for medium power applications. Furthermore, its low capacitance makes it suitable for high-speed data circuits. Finally, it has a built-in discharge current protection feature that helps ensure efficient protection of the connected devices.
