TVS - Varistors, MOVs are commonly used in protection circuits for electronic controllers, equipment, and systems. The V18MLA0805WH is an especially useful component to add such protection. It acts as a circuit breaker that would limit inrush current and discharge static electricity to ground. It is mainly used for over voltage protection.

The working principle of the V18MLA0805WH is based on a ZNOV Switching Regulator that uses a low voltage DC power supply, a voltage-controlled switch, and a low impedance power inductor. When there is an over voltage spike, the voltage across the capacitor will increase. When it reaches a certain threshold, the ZNOV Switching Regulator will be triggered and open the energy loop, so that current will not flow across the load or other circuit elements. This will limit inrush current, and discharge static electricity to ground.

The application field of the V18MLA0805WH includes power protection, over voltage protection, transient voltage protection, and EMI/RFI protection. In power protection, it can be used in situations where the electronic equipment is continuously exposed to inrush current and transients. This component can provide protection from major spikes that could cause power failure or damage to the equipment. In over voltage protection applications, it will protect electronic components by limiting the amount of voltage that passes through them. This prevents overheating, malfunction, or damage to the system.

The V18MLA0805WH is also used in transient voltage protection applications to protect against surges caused by power lines being hit by lightning or by AC power sources. In EMI/RFI protection, this component is used to limit the amount of high frequency interference that is passed through a circuit. This can be especially important for sensitive radio, communication, and instrumentation equipment and systems, where interference may cause erroneous readings or data corruption.

The V18MLA0805WH is a reliable and useful component in protection circuits and offers multiple advantages. It is relatively low cost and can be easily integrated into any protection circuit. It is a low profile component that can be easily mounted where space is limited. Additionally, it has an ultra-fast response time which ensures reliable protection. The component is UL and CSA recognized and is RoHS compliant.
