The MAX4867ELT+T is part of the Transil SOT23-5 family of Transient Voltage Suppressors (TVS) and is classified as a “Mixed Technology” product. It combines a metal oxide varistor (MOV) and an avalanche diode into one package. This type of TVS is capable of clamping surges up to 7500W, providing both protection and an open circuit when no surge is present.

The type of Mixed Technology used in the MAX4867ELT+T is a Metal Oxide Avalanche Diode. This type of device combines two different technologies, a metal oxide varistor (MOV) and an avalanche diode, into one package. It is used for protection of sensitive electronic components from over-voltage transients. The device is designed to dissipate and absorb energy during surges, providing an open circuit during normal operation, and a low-impedance path to ground during a surge event.

The MOV is the energy absorbing component of the device. It is a resistor-like resistance element made up of zinc oxide grains. Every time a surge event occurs, the MOV will dissipate a certain amount of energy. It is designed to withstand many surge events and will maintain a low leakage current even after multiple cycles of surge events.

The avalanche diode is used to provide a low impedance path to ground during a surge event. This low impedance will be able to effectively limit the amount of voltage presented to the downstream circuitry during a surge event. The avalanche diode will respond to surge events faster than the MOV and is designed to absorb most of the high-energy surge current.

The combination of the MOV and the avalanche diode provides a robust, effective solution for protecting against high-energy transients. It also minimizes leakage current during normal operation, making it ideal for sensitive electronic components. The MAX4867ELT+T is designed to operate over a wide range of input voltage from 4V to 66V.

The MAX4867ELT+T can be used for a variety of applications including consumer electronics, automotive, industrial, communications, and medical electronics. It is particularly useful in LCD televisions, audio amplifiers, UPS systems, and other electronics that are subject to power surges or voltage spikes. The device can provide both over-voltage protection and over-current protection, as well as provide a low-impedance path to ground in the event of a surge.

In summary, the MAX4867ELT+T is a low-cost, effective solution for protecting sensitive electronic components from over-voltage transients. It is a Mixed Technology product combining a metal oxide varistor and an avalanche diode for superior protection. The combination of these technologies also minimizes leakage during normal operation. The MAX4867ELT+T is particularly useful for LCD TVs, audio amplifiers, UPS systems, and other electronics that are subject to power surges or voltage spikes.
