2PRO DEVICES

The 2Pro product is an integrated overcurrent/

over-voltage protection device. The RoHS-compliant

component 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 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.
