2PRO DEVICES The 2Pro product is an integrated overcurrent/ over-voltage protection device. The RoHS-compliant c omponent incorporates PolySwitch PPTC (Polymeric Positive Temperature Coefficient) technology and MOV (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 c ondition is removed and power is cycled, 2Pro de vices 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 ent erprise environments as the primary means of voice delivery r equires 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 pr ovide ESD protection.
