TVS (Transient Voltage Suppressor) diodes provide protection from voltage transients caused by lighting, static charge, etc. They are mostly used in power supply systems and data communications to protect electronic equipment from damage due to over voltage events. The MXLSMLJ78AE3 is a voltage transient suppressor diode developed by NEXPERIA that has a low clamping voltage and high peak pulse power. This product is specifically tailored for telecom and industrial applications.

Application Field

The NEXPERIA MXLSMLJ78AE3 TVS Diode is intended for use in industrial and telecom applications that require protection against transients and surge voltages. Applications include equipment such as PoE (Power over Ethernet) devices, network switches, and communications servers.

These diodes are also used for protecting power inputs on applications such as chargers, power supplies, and USB supplies. The low capacitance of these diodes also makes them suitable for protecting signal and data lines, which helps prevent over-voltage events from damaging sensitive electronics.

Working Principle

The NEXPERIA MXLSMLJ78AE3 TVS Diode works by clamping impulse voltages and limiting currents in order to prevent voltage transients from reaching the device’s output or input. The diode is designed with a p-n junction that can quickly respond to voltage transients and short-circuits, allowing it to act as an electrical barrier that diverts any excess energy to the ground.

When a voltage spike, surge, or static charge occurs, the diode is triggered and begins to conduct current at its positive terminal. The current is then directed through the diode’s p-n junction and into the device’s ground connection. This results in a voltage limit at the point of entry, ensuring that the device’s components remain protected and safe from potential damages associated with over-voltage events.
