41 2pro devices 6 the 2pro product is an integrated overcurrent/over- voltage protection device. the rohs-compliant component incorporates polyswitch pptc (polymeric positive temperature coefficient) and metal oxide varistor technology in a single device to help reduce board space requirements and component count. damage to telephony communications equipment can be caused by various sources including lightning, electrostatic discharge (esd), power contact and induction with ac lines. the 2pro tm2p-10271 devices help provide current limiting during overcurrent events, and voltage clamping during overvoltage events. after a fault condition is removed and power is cycled, 2pro devices will reset so that the equipment remains operational. the 2pro device helps address the need for resettable circuit protection devices for use in cost-sensitive pstn (public switched telephone network) and voip (voice over internet protocol) telephony equipment. the widespread use of voip gateways in homes and enterprise environments as the primary means of voice delivery requires the utmost safety and reliability in equipment. 2pro circuit protection devices help manufacturers comply with global safety standards, including ul 60950, tia-968-a, iec 60950, and itu-t k.20/k.21. the ul 497a listed protector also helps provide esd protection. ? set-top boxes ? security systems ? mdf modules ? analog and isdn linecards ? single device helps reduce component count and footprint ? helps reduce warranty returns ? helps equipment comply with surge tests per: tia-968-a, iec 60950, itu-t k.20/k.21 ? helps simplify ul 60950 testing ? helps equipment comply with ul 60950 ? rohs compliant ? halogen free (refers to: br 900ppm, cl 900ppm, br+cl 1500ppm) ? single overcurrent, overvoltage and esd protection device ? resettable overcurrent protection ? ul 497a listed protector (#e258475) ? cordless telephones ? voip gateways ? fax machines ? data modems benefits features applications 2pro devices
