Transient Voltage Suppression (TVS) diodes, such as MXSMCJ90A, are critical components in the protection of circuits from electrical overstress (EOS) caused by electrostatic discharges (ESD), electrical fast transients (EFT) and lightning transients. MXSMCJ90A is designed to protect against ESD strikes rated to the IEC 61000-4-2 international standard up to ±30kV contact. It also provides protection from EFT bursts up to 2.5kV and lightning surges up to 33kV.Generally, when looking for protection from ESD, EFT, and lightning transient, it is essential to choose an appropriate TVS diode such as MXSMCJ90A. Depending on the application, the selection of a TVS diode will depend on a number of factors such as breakdown voltage, surge rating or the peak peak power dissipation of the device. In applications where power dissipation is an important factor, MXSMCJ90A offers a low thermal resistance of ~2.5°C/W and a peak pulse power of 400W.MXSMCJ90A diodes are particularly useful in a variety of different application fields such as automotive, consumer electronics and communications. This diode is ideal for protecting sensitive components from overvoltage and short circuit in automotive and other transportation equipment. In semiconductor and communication systems, MXSMCJ90A can be used for protecting circuits used in the automotive sector from ESD, EFT, and other transients.The working principle of MXSMCJ90A involves the principle of reverse polarization. When an excessive voltage is applied to the diode, it\'s PN junction become forward biased and the current through the diode begins to rise exponentially. This flow of current carries the energy away from the device and prevents the device from being damaged by the excessive voltage. When the current reaches the breakdown voltage of the diode, the device conducts for the rest of the applied voltage.In conclusion, MXSMCJ90A is an extremely important device for protecting sensitive circuits from ESD, EFT and lightning transients. It is widely used in many application fields, such as automotive, consumer electronics and communication systems, to provide safe, reliable and long-term protection. Its working principle of reverse polarization helps the device to conduct and absorb the energy from the applied voltage and thus prevent expensive circuit damage.
