Littelfuse’s LA varistor series of transient voltage surge suppressors are radial leaded varistors designed to be operated continuously across AC power lines. They are UL recognised, require very little mounting space and are offered in various standard lead forms.

The SM20 device is a surface-mount metal oxide varistor for use in applications requiring hi-energy and transient current capability. The AC rated parts are designed to operate continuously across AC power lines, whilst the DC parts are suitable for automotive applications. This series features a Nylon molded package with folded tin plated metal leads for soldering to board. The SMD series is based on radial 20mm internal varistor element with similar characteristics to Littelfuse’s LA/ZA series of varistors.

The SM7 device is a plastic-encapsulated surface mount MOV in a PPS material molded package with tin-plated terminal which is fully qualified in lead-free soldering and available for both reflow and wave soldering process. Littelfuse’s SM7 is constructed with 7mm varistor element disc and has a maximum operating ambient temperature of 85°C with a peak pulse current of 1200A.
