Transient Voltage Suppressor (TVS) diodes are a type of voltage-regulating device. They provide short-term protection against large, transient voltage spikes. The MXRT100KP40CA is a particularly robust member of this family, offering a 400-W peak pulse power dissipation level, and a standoff voltage of 400 V. It has a low clamping voltage, and surge capability, making it suitable for a variety of high power applications.

Application Areas

The MXRT100KP40CA is a versatile TVS diode, with many possible applications. Its 400-W power handling capabilities make it ideal for protecting sensitive devices from short, high-voltage spikes that can cause instantaneous damage. It is particularly useful in applications such as:

• Power supply protection – The MXRT100KP40CA overloads the voltage spike, protecting the power supply circuitry in industrial, commercial and residential applications from transients.
• Electronic automotive systems – The MXRT100KP40CA can be used to protect sensitive electronics from high-voltage transients in cars, such as those generated by lightning, and other transient sources.
• Data communications – The device\'s low clamping voltage and high transient suppression capability make it ideal for data communication applications, including cellular networks, Ethernet or DSL.
• Audio systems – The MXRT100KP40CA can be used to protect home audio equipment from high-powered transients and surges.

Working Principle

The MXRT100KP40CA is designed to protect sensitive equipment from damaging transients, including electrical spikes caused by lightning, electrostatic discharge, and short circuits. It utilizes a Zener diode, which has a reverse breakdown voltage. When the voltage across the Zener diode exceeds this break down voltage, the diode will conduct, allowing a surge of current to flow. This conducts the transient energy away from the protected device, ensuring it remains safe from harm.

The MXRT100KP40CA is designed to take up to 400-W of transient power. It has a maximum reverse leakage current of 3 µA, and a forward operating current of 3 amps (µA = microamp). It also has a very low clamping voltage rate, and can withstand high-powered surges of up to 400 V.

The device\'s low design capacitance reduces the risk of latch up. It features an ESD protection capability of up to 25 kV, meaning it can protect against electrostatic discharges of up to 25 kV. It also features a low maximum voltage drop (VDR), meaning that it will not present a large voltage drop when in operation.

Conclusion

The MXRT100KP400A is an extremely robust and versatile TVS diode, suitable for a wide range of applications. Its 400-W power handling capability makes it ideal for high-powered applications, and its low clamping voltage ensures it can effectively protect against transients. The device\'s low capacitance and high ESD protection capability also makes it a safe and effective choice for protecting device circuitry from lightning strikes, electrostatic discharges and short circuits.
