V320SM7 Description

Short technical summary and product information.

The Littelfuse V320SM7 is a plastic-encapsulated surface mount metal-oxide varistor (MOV) from the SM7 series. It is designed for overvoltage protection in AC power applications and is electrically equivalent to leaded LA/ZA series varistors.

 

Key electrical specifications include a maximum AC voltage rating of 320V, maximum DC voltage rating of 420V, and a typical varistor voltage of 513.5V at 1mA DC. The device can handle peak pulse currents up to 1.2kA (8/20µs waveform) and absorb up to 25J of energy (10/1000µs waveform). Clamping voltage is 775V maximum at 10A.

 

The V320SM7 is housed in a 2-SMD J-Lead package suitable for reflow and wave soldering processes. It operates over an ambient temperature range of -40°C to +85°C with no derating required up to 85°C. The device is RoHS compliant and lead-free.
