TVS or transient voltage suppressor diodes provide electrical protection from overvoltages, also known as surge protection. M1.5KE12CAE3 is a unidirectional trisil low capacitance TVS diode, designed to protect sensitive electronic components from overvoltage or transient electrical events. It provides both overcurrent and ESD protection to sensitive electronic equipment and circuits.

Unlike other TVS diodes, M1.5KE12CAE3 offers a wide operating temperature range between -55 °C and 175 °C. It also features very low capacitance, good voltage clamping, high surge current handling capability and fast operating time, making it ideal for a number of applications. Some of its common applications include consumer electronics, medical equipment, industrial automation, automotive electronics, aerospace and avionics applications.

M1.5KE12CAE3 typically operates in a uni-directional (positive voltage polarity) between -6V to 18V. This TVS diode has an ESD rating of ±15KV contact and ±20KV air discharge, and the ability to handle surge currents up to 15A. Its low capacitance makes it capable of filtering high frequency transients, which is very useful for applications that require fast switching or signal transmission.

The working principle of M1.5KE12CAE3 could be explained with the help of a typical NTVS (Negative Transient Voltage Suppressor) circuit. In this circuit, the diode is placed in series with the device it is protecting. When an overvoltage occurs, the diode will conduct the current, attenuating the voltage before it reaches the device. It acts as a voltage limiter and helps to protect the device from overvoltage.

Thus, the M1.5KE12CAE3 diode provides reliable circuit protection from overvoltages and transients. It is designed to clamps the voltage to its rated values while allowing current to flow through the circuits. This diode is highly reliable and suitable for applications in various fields including consumer electronics, medical equipment, industrial automation, automotive, aerospace, and avionics.
