Littelfuse LSP05 and LSP10 Series Surge Protection Devices

Littelfuse LSP05 and LSP10 Series LED Lighting Surge Protection Devices provide robust protection for outdoor and commercial LED lighting fixtures against transient overvoltage conditions. These devices use thermally protected varistor technology to prevent catastrophic failures and fire hazards, even under extreme conditions. The built-in thermal disconnect function enhances safety by isolating the device during end-of-life or sustained overvoltage events. The LSP05 features a maximum discharge current of 10kA (8/20 µs waveform) and supports a continuous voltage range of 150VAC to 510VAC. These devices meet IEC61643-11 Class II and IEEE C62.41.2 standards and offer IP66-rated protection. The LSP10 series offers a higher maximum discharge current of 20kA (8/20 µs waveform) and provides parallel or series connection options for additional flexibility. The LSP05 operates within a temperature range of -45°C to +85°C, with a storage range extending to +125°C while the LSP10 series have similar temperature ranges, with a maximum storage limit of +110°C. The LSP05 and LSP10 are suitable for outdoor and commercial LED lighting applications, including roadway, tunnel, flood, and traffic lighting, as well as digital signage and parking area illumination.
