Transient Voltage Suppression (TVS) diodes are used to protect electronics from voltage spikes in applications such as power supplies, oscillators, medical equipment, and automobiles. The MXLCE60AE3 is a specialised TVS diode designed to protect against transient surges even in the most extreme conditions.

At the heart of the TVS design is a semiconductor diode which can be either Silicon or Zener. Silicon diodes are more resistant to current, but less resistant to voltage, while Zener diodes are more resistant to voltage and less resistant to current. MXLCE60AE3 is a Zener diode that uses the junction breakdown mechanism and reverse avalanche breakdown mechanism for its operation to protect against transient surges.

The MXLCE60AE3 can clamp a transient voltage within a range of 20V to 1000V, and is optimised to absorb up to 90A of energy during surge events with a peak pulse current of 3 × 10⁹A. The device has a very low response time and can clamp off a transient surge within 100ns. This makes it ideal for high frequency applications or where critical components require fast protection from spikes.

The device comes in a dual-side cooled and high-power robust mechanical design, which offers even better protection against thermal shocks and overvoltage conditions. The device is open-air safe, meaning it can be used in applications with contaminant particles and dust, as well as in dry or humid environments. It is also protected against electrostatic discharge (ESD).

The MXLCE60AE3 is suitable for a wide range of applications, including AC/DC converters, high-side switching supplies, high voltage isolated supplies, microcontrollers, power distribution networks, automotive, and industrial controllers. The device can also be used for telecommunications and RF equipment, as well as medical and power supplies.

The working principle of the MXLCE60AE3 is simple yet effective. When a transient voltage surge occurs, the device clamps it between its two junctions and converts the energy to heat, thus preventing the surge from reaching the electronics. This effectively creates an artificial barrier, providing a secure environment for the electronics. As the device is heated up, its reverse-current supply is cut off, preventing any further damage to the device.

The MXLCE60AE3 is an excellent device for protecting electronics from transient voltage surges and the damaging consequences of those surges. It is designed for high-performance applications, its mechanical construction is robust and reliable, and it has a reliable and consistent response time. Combined with its low-power operation, this makes it an excellent choice for a wide range of applications.
