The V30MLA0603NH is a surface-mount automated placement varistor (also known as a transient voltage surge suppressor) from the V30 series of varistors manufactured by the Japanese company Murata. This device is specifically designed to protect electronic systems from over-voltage, over-current and surge related transients.

The V30MLA0603NH is an unidirectional (Bi-directional) TVS (Transient Voltage Suppressor) device in a 0603 case size. This package is traditionally used on most surface-mount automated placement boards due to its very small size. The device is AEC-Q200 qualified, meaning it has been tested and passed the requirements of the automotive industry to withstand higher levels of temperature and humidity.

The working principle on the V30MLA0603NH is to divert the energy from over voltage transients away from sensitive components and circuits, by providing a clamping path when the rated voltage is exceeded. The maximum peak pulse current of the V30MLA0603NH is 275A, the peak pulse power rating is 4.4kW and its peak pulse energy rating is 8.1Joules. The operating temperature range of this device is –55°C to +125°C.

The V30MLA0603NH can be used in a variety of applications where high transient protection is required. These include Automotive circuits, Automated Test Equipment, Industrial Process Control, Telecommunication equipment, Smartphones, Digital audio equipment, Set Top Boxes and Television sets.

Aside from surge protection, this device can also be used as a circuit breaker and ESD protection. In circuit breaker applications, the V30MLA0603NH can provide reliable over-current protection for sensitive equipment such as computers and consoles. For ESD protection, the device can absorb electrostatic discharges up to 8kV.

Overall, the V30MLA0603NH is a small, versatile surface-mount device capable of providing over-voltage, over-current and surge protection in a variety of applications. Its relatively low price and small package size make it a popular choice for many automotive and industrial systems.
