The Littelfuse TMOV20R320E is a metal oxide varistor (MOV) designed for overvoltage protection in AC and DC circuits. It features a typical varistor voltage of 510V, with a minimum of 459V and maximum of 561V. The device can handle surge currents up to 10kA and has an energy rating of 270J.
This varistor is housed in a 20mm disc package with through hole mounting, making it suitable for board-level assembly. It operates over a temperature range of -55°C to 85°C. The component is thermally protected, which helps prevent thermal runaway under sustained overvoltage conditions.
Typical applications include power supply input protection, industrial equipment, and consumer electronics where transient voltage suppression is required. The capacitance is 750 pF at 1 MHz, which should be considered in high-frequency circuit designs.
