2Pro Devices

The 2Pro product is an integrated overcurrent/overvoltage

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 and TM2P-10271E 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.

With the introduction of the 2Pro devices Raychem Circuit

Protection 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.

Benefits:

• 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

Features:

• Single overcurrent, overvoltage and ESD

protection device

• Resettable overcurrent protection

• UL 497A listed protector (#E258475)

• RoHS compliant

Applications:

• Cordless telephones

• VoIP gateways

• Fax machines

• Data modems

• Set-top boxes

• Security systems

• MDF modules

• Analog and ISDN linecards
