Transient Voltage Suppression (TVS) diodes are widely used in a variety of circuits and are essential for providing effective protection against surges. The M1.5KE68CAE3 is a unidirectional TVS diode specifically designed for general-purpose ESD and surge protection in consumer electronics and other low voltage applications. This diode is very robust, with peak surge current capability of up to 40A (8/20μs, 20A (2ms) repetitive).

The M1.5KE68CAE3 is a low-cost, low-leakage diode with a high breakdown voltage of 68 V. It is suitable for protecting sensitive analog and digital lines such as Ethernet, USB, I2C, UART, and other low voltage communication lines against transient voltages. It also provides effective protection against secondary power-line or power distribution network faults, such as those caused by lightning strikes or other transient voltage events.

The working principle of the M1.5KE68CAE3 is quite simple. When the voltage across the diode exceeds the breakdown voltage, the diode becomes forward biased and conducts current, shunting the transient voltage away from the protected circuit. This is known as the clamping action which helps to protect the circuit from any harmful transient events. The diode is designed with a low capacitance discharge path and low forward voltage drop, making it well suited for protecting high frequency circuits.

The M1.5KE68CAE3 is packaged in a DO-213 package, making it suitable for use in both surface mount and through-hole applications. It is also UL recognized, which makes it compliant with international safety standards. The diode has a very low leakage current, so it can be used in circuits requiring high accuracy, such as industrial and automotive control systems. The device is also resistant to high humidity and extreme temperatures, making it suitable for use in a wide variety of environments.

Overall, the M1.5KE68CAE3 is a robust, low-cost solution for providing surge protection to a variety of applications. It has a low leakage current and high breakdown voltage, making it ideal for protecting sensitive analog and digital lines, as well as providing protection from secondary power line faults and other transient voltage events. Its low capacitance discharge path and low forward voltage drop make it well suited for protecting high frequency circuits. It is also UL recognized, which makes it compliant with international safety standards. Its DO-213 package makes it suitable for use in both surface mount and through-hole applications. Finally, its high resistance to humidity and extreme temperatures make it suitable for use in a wide variety of environments.
