MXLSMLJ85AE3 Circuit Protection

TVS - diodes have become increasingly popular over the past decade, and the MXLSMLJ85AE3 is one such device. This device is a (Transil) transient voltage suppressor (TVS) with a 5V breakdown voltage, and it is used to protect against electrical surges. It does this by quickly conducting surge current and dissipating the energy to the ground, thereby protecting the connected equipment and components.

The MXLSMLJ85AE3 is an unipolar, single-pole varistor with excellent noise protection characteristics. It has a built-in protection diode that can withstand peak reverse voltage up to 5V, and it is capable of dissipating a maximum power of 250W. Its response time is in the range of 1ns to 1ms, depending on the surge current, and its breakdown voltage is 5V. The peak pulse power is 400W and the clamping voltage is 10V. It also has excellent stability, robustness, and reliability.

The application fields of the MXLSMLJ85AE3 include automotive electronics, industrial electronics, personal electronics, and medical electronics. This device is mainly used to protect sensitive electronics from electrical overstress (EOS) due to lightning and power spikes. In the automotive arena, it is used in engine control units, antilock braking systems, and sensors. In industrial electronics, it is used in industrial equipment and alarm systems. In personal electronics, it is used in televisions, computers, and other consumer devices. Finally, in medical electronics, it is used in pacemakers and other bioelectric monitoring devices.

The working principle of the MXLSMLJ85AE3 is based on the PN Junction diode, which acts as a back-to-back switch. When a surge exceeds the breakdown voltage of 5V, the diode will turn on and conduct, thereby providing a low impedance path for current to flow to the ground. Thanks to this conductive path, the connected equipment is protected from the surge. The conductive path also helps reduce the peak voltage, thus providing an extra layer of protection.

In conclusion, the MXLSMLJ85AE3 is a robust and reliable transient voltage suppressor used to protect sensitive electronics from electrical overstress due to lightning and power spikes. This device has a 5V breakdown voltage and a peak pulse power of 400W. Its application fields include automotive electronics, industrial electronics, personal electronics, and medical electronics. Its working principle is based on the PN Junction diode, which acts as a back-to-back switch to quickly provide a low impedance path for current to flow to the ground.
