TVS (Transient Voltage Suppressor) diodes are becoming more and more popular in the electronics industry. They are used in a variety of applications including circuit protection and EMI filtering. The MSMLJ85A/TR (Transil) is one example of a popular TVS diode. This diode is suitable for applications ranging from TVS diode arrays and overvoltage protection devices to ESD protection. In this article, we will discuss the applications of the MSMLJ85A/TR and its working principle.

Applications of MSMLJ85A/TR

The MSMLJ85A/TR TVS diode is an ideal choice for protecting sensitive electronic circuits such as computers, telecommunications equipment, audio equipment, and industrial and automotive circuits from overvoltage damage. It can be used as a single component or in arrays to protect multiple circuits. The MSMLJ85A/TR diode is designed for applications requiring low clamping voltages and fast response times. This diode is also suitable for protecting circuits in harsh environments such as automotive applications and for repelling ESD attacks.

Working Principle of MSMLJ85A/TR

The MSMLJ85A/TR diode is a three-layer diode composed of a PN junction diode, a PN junction thyristor, and a Zener diode. The diode conducts current only when the voltage applied to the anode is higher than the Zener breakdown voltage. When the voltage across the anode and cathode exceeds the Zener breakdown voltage, the thyristor will start to trigger and turn on. This triggers the PN junction diode to start conducting current. The MSMLJ85A/TR diode is designed to clamp the applied voltage to an acceptable level. The PN junction diode and the thyristor will recombine to turn off the diode when the applied voltage falls below the Zener breakdown voltage. In this way, the diode offers efficient protection against overvoltage damage.

Conclusion

The MSMLJ85A/TR is a high-efficiency and fast-response TVS diode designed for applications that require low clamping voltages and fast response times. This diode is suitable for a range of applications including overvoltage protection, EMI filtering, and ESD protection. Its three-layer design ensures that it can protect sensitive circuits from overvoltage damage. The diode operates by combining a PN junction diode, a PN junction thyristor, and a Zener diode to provide effective protection.
