TM2P-10271-2 - TE Connectivity

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 and

ESD surges, 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 communications 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.
