MXPLAD18KP85CA

TVS - Diodes

The MXPLAD18KP85CA is a two-terminal, unidirectional diode widely used in TVS (Transient Voltage Suppressor) applications. This diode is specially designed for applications where high-energy, ultrafast switching is needed to support system and component protection against voltage transients such as ESD (Electrostatic Discharge).

The main working principle of the MXPLAD18KP85CA is based on the avalanche breakdown effect, which is the phenomenon of current increasing drastically due to device-intrinsic conduction mechanisms when increasing the reverse voltage applied across the diode. The reverse voltage must exceed the protection voltage rating of the diode in order to trigger the avalanche breakdown effect. Once this happens, the diode quickly switches from the off-state (reverse blocking mode) to the on-state (forward conducting mode). In the on-state, the diode rapidly takes up a large amount of energy due to the sudden increase in current.

The MXPLAD18KP85CA is mainly employed in transient voltage suppression applications for the protection of AC/DC converter and power supplies, telecom and HVAC equipment, industrial equipment and automotive systems. This diode helps protect these electronic systems against high-energy transient voltage surges from ESD, lightning and other voltage spikes.

In order to ensure its effective performance in protection applications, the MXPLAD18KP85CA should be connected directly to the system and the two terminals must lie in the same electrical ground potential. The diode can be mounted either on a Printed Circuit Board (PCB) or directly soldered onto the system, and it should be placed near the source of the ESD or other transient voltage surge to ensure fast response.

In conclusion, the MXPLAD18KP85CA diode is a versatile device specially designed for fast switching of transient voltage surges, providing protection to a wide variety of electronic systems and components.
