The MX15KP90AE3 TVS Diode is a high power protection device designed to protect sensitive equipment from ESD, electrostatic discharge, and EFT, electrical fast transients. It has been widely used in automotive, industrial, and consumer applications for decades, and is a reliable, safe, and cost-effective solution to safeguard against transient voltage surges.

The MX15KP90AE3 is a low-capacitance, uni-directional diode with a breakdown voltage of 9V. It features a protection capacity of 15kA (8/20µs pulse), 40A (DC) current surge capability, and a peak pulse power rating of 400W. The device features an ultra-low clamping voltage, 8V maximum, with an low leakage current of 1.0 µA (maximum, at 8V). The package size of this TVS Diode is 0603, making it ideal for space-constrained designs.

The primary application of the MX15KP90AE3 is to protect against transients related to electrostatic discharge and other fast transient events. It is commonly used in automotive and industrial equipment, including electronic fuel injection systems, airbag systems, control systems, and transformers, to provide a high level of protection without impeding system performance. It is also widely used in consumer applications such as USB hubs, motherboard ports, sound cards, printers, and other audio/video equipment.

The MX15KP90AE3 has a working principle that is based on the electrical characteristic of a Zener diode. When the voltage level of an incoming transient exceeds its breakdown voltage level, the TVS diode will immediately clamp the voltage and absorb the transient energy. This is achieved by diverting the high voltage transient away from the sensitive components and grounding it safely. The device will then remain “latched” in the conducting state until it is reset manually or by power cycling the system.

The MX15KP90AE3 is a highly effective TVS Diode for protecting sensitive systems from ESD, EFT, and other transient voltage surges. Its low capacitance and low leakage current make it ideal for space-constrained designs, while its high breakdown voltage ensures effective levels of protection. This device is widely used in both automotive and consumer applications, and has been on the market for decades.
