The New AK15 devices provide the highest level of TVS protection available in the industry. Littelfuse introduces its AK15 Series of Transient Voltage Suppressor (TVS) devices to prevent the destruction of expensive electronic gear from high-energy transients. With their 15kA (8x20 μs pulse)surge current rating, AK15 devices provide the highest level of TVS protection available in the industry. They will be especially useful to manufacturers of mission critical equipment such as cellular telecom infrastructure apparatus, industrial transient voltage surge suppression (TVSS) systems, railway trackside signaling circuitry, highway traffic control signals, and other industrial control equipment. The AK15 Series was designed to provide protection against transients generated by nearby lightning strikes and high-level voltage surges that occur on electrical lines when large industrial equipment is switched on and off.
