V420LA10 Description

Short technical summary and product information.

The V420LA10 is a metal oxide varistor (MOV) designed for overvoltage protection in electronic circuits. It is manufactured by Harris Semiconductor and features a disc package of 10mm diameter with through-hole mounting. The varistor has a maximum AC voltage rating of 420V and a maximum DC voltage rating of 560V. Its varistor voltage ranges from 612V minimum to 748V maximum, with a typical value of 680V. The surge current rating is 2.5kA (8/20µs waveform), and it can absorb 55J of energy. Typical capacitance is 140pF at 1MHz. The operating temperature range is -55°C to 85°C. This component is suitable for use in power supply protection, industrial equipment, and consumer electronics where transient overvoltage suppression is required. The single-circuit design and radial lead configuration facilitate easy integration into printed circuit boards.
