MXP4KE7.5AE3 TVS - Diodes Application Field and Working Principle

MXP4KE7.5AE3 are Transient Voltage Suppression (TVS) diodes designed to protect sensitive electronic devices from destructive voltage transients caused by lightning, electrostatic discharge (ESD), and other transient overvoltage events. This series of unidirectional devices offer 1500 W (8/20 μs) peak pulse power dissipation and are presented across a broad range of breakdown voltages from 14 to 170 V. MXP4KE7.5AE3 is typically employed in the protection of automotive and telecom circuit applications such as CAN Bus, I2C Bus, and other high speed digital systems. With a maximum leakage current of just 5μA at13V, it can provide superior performance and superior overvoltage protection in variable temperature conditions between -55℃ and +175℃.

Working Principle of MXP4KE7.5AE3 TVS - Diodes

TVS diodes are used to suppress transient overvoltage spikes in applications such as automotive and data/telecom lines. They differ from standard rectifier diodes because their behavior is nonlinear, as they are designed specifically to limit the peak transient amplitude of a given power or signal line. They do this by applying reverse bias to the diode, causing current to flow in the opposing direction before the voltage spike destroys the protected device or causes signal distortions.The MXP4KE7.5AE3 offers superior performance over other types of protection devices, including the ability to operate at lower capacitive load values than standard TVS devices. The internal structure of the device is designed to allow the peak pulse current to be limited, allowing it to function under higher rated power than traditional TVS. The maximum peak pulse power (8/20μs) rating for the MXP4KE7.5AE3 is 1500 W at 14 V, which is significantly lower than a conventional device rated at 2500 W at 14 V.

Conclusion

MXP4KE7.5AE3 TVS - Diodes are unidirectional devices which offer 1500 W (8/20 μs) peak pulse power dissipation and are presented across a broad range of breakdown voltages from 14 to 170 V. These devices are employed in a wide variety of automotive and telecom circuit protection applications, offering superior performance in terms of overvoltage protection and low leakage current. Working on the principle of reverse bias, they are designed to limit the peak transient voltage and current in power and signal lines respectively, allowing them to function under higher rated power than traditional TVS devices.
