2015 Littelfuse LED Lighting Design Guide www.littelfuse.com LED Lighting Design Guide Table 6 is a comprehensive part selection guide for commercial and outdoor lighting systems organized by surge level that needs to be met. It provides both overcurrent and overvoltage component recommendations that will pass both safety and surge starndards respectively.

Standard method was used for testing the MOVs per datasheet specifications which consisted of driving 10kA through the part with the generated combination wave. Peak voltage was adjusted to a bit higher than 20kV in order to drive exactly 10kA of peak current. In real world events, actual peak current through the luminaire with typical circuit impedance path will lik ely be lower. Littelfuse has tested the above part selections to a more stringent level as it complies with our internal testing standards. The TVS diodes and PLED options were not tested due to the custom nature of each commercial lighting design. The parts highlighted in green are design-registrable. Table 6.
