TVS - Diodes are electrical components that provide bidirectional protection of equipment from voltage spikes. TVS - diodes are available in both discrete and integrated form, depending on the application. MSMLJ85AE3/TR is a type of TVS – Diode that is used to protect from electrical surges in high power applications, such as power pedestals and air conditioners.

The MSMLJ85AE3/TR is a Transient Voltage Suppressor diode that is hermetically sealed in a ferrite package. It has three terminals, named anode, cathode, and guard electrode. The cathode and anode is where the current flow in a circuit originates from and ends. The guard electrode is connected between the cathode and anode in order to provide additional protection from surges.

The MSMLJ85AE3/TR also has a peak pulse current rating of 85A, which is very high when compared to other TVS-diodes with similar ratings. Combined with its low on-state voltage of 8V, this makes it an attractive choice for applications that require high surge current protection. The MSMLJ85AE3/TR also has a low capacitance of only 1.15pF, thus reducing interference from other signals.

The main application fields of the MSMLJ85AE3/TR are power supplies, telecom equipment, power pedestals, automotive electronics, and air conditioners. It is designed to protect from overcurrent, overvoltage, and electrostatic discharge. Overcurrent protection is achieved through a low clamping voltage of 8V, while overvoltage protection is achieved by a high peak pulse current rating of 85A. Electrostatic discharge is protected through the guard electrode, which is connected between the anode and cathode.

The working principle of the MSMLJ85AE3/TR is relatively simple. When the voltage across the device reaches its threshold value, the device begins to conduct current, which reduces the voltage across the device. This in turn reduces the current flowing through the device. As the voltage drops, the current decreases, and eventually reaches its original value. The device then turns off and goes back to its normal operating state.

The MSMLJ85AE3/TR is a powerful and versatile TVS-diode designed for high-current applications. Its low on-state voltage and high peak pulse current rating makes it an attractive option. Its three terminals provide protection from overvoltage, overcurrent, and electrostatic discharge. This makes the MSMLJ85AE3/TR an ideal choice for applications such as power supplies, telecom equipment, and power pedestals.
