MXLCE70AE3 is a TVS (transient voltage suppressor) diode, which is designed to protect sensitive electronic components from electrical overstress. It is used in a wide variety of applications from consumer electronics to automotive, industrial, and telecommunications systems. This diode is suitable for two different applications – as a low capacitance unidirectional diode and as a bidirectional TVS diode.

First, as a low capacitance unidirectional TVS diode, the MXLCE70AE3 exhibits very low leakage current even when the voltage stress exceeds the Breakdown Voltage of the diode. This ensures that the load has maximum protection against electrical overstress. This diode is available in two different voltage versions – one rated for 70V and another rated for 65V.

Second, as a bidirectional TVS diode, the MXLCE70AE3 provides two-stage protection against electrical overstress. The two stages are voltage dimension and current clamping. The voltage dimension function limits the peak voltage across the load, while the current clamping mechanism clamps the current spikes when the voltage exceeds the breakdown voltage. This provides a highly effective protection solution for sensitive electronic components.

The working principle of the MXLCE70AE3 is based on the inductive-capacitance (LC) effect. When a voltage is applied to the diode, a current through the device begins to flow. This current produces a magnetic field around the diode, which in turn creates a capacitance. This capacitance then absorbs the transient energy from the environment, thus preventing overvoltages from reaching the load.

The MXLCE70AE3 has a maximum peak working voltage of 1.2KV and a maximum leakage current of 1mA at 10mA. It has an average clamping voltage of 35V and a breakdown voltage of 68V. It is available in various packaging styles, including flat leaded packaging and SMD (Surface Mount Device) packaging. The diode is also RoHS compliant.

The MXLCE70AE3 is a highly effective way to protect sensitive electronic components from transient voltage stresses. This diode is suitable for many different applications, from consumer electronics to automotive, industrial, and telecommunications systems. With its two-stage protection mechanism, it provides a reliable protection solution against electrical overstress.
