Circuit protection devices

Raychem Circuit Protection, a business unit of Tyco Electronics, has released its 2Pro device series that features integrated overcurrent/overvoltage circuit protection technology designed to help prevent damage to telephony communications equipment.

According to the press release, the device's small footprint, resettable functionality and coordinated protection capabilities allow for use in a wide range of telephony and VoIP equipment applications such as cordless phones, VoIP gateways, data modems, STBs, security systems, main distribution frame modules, analog linecards and ISDN linecards.

The RoHS-compliant 2Pro device incorporates PolySwitch polymeric positive temperature coefficient resistor overcurrent technology with an metal oxide varistor component into one thermally protected device to help provide current limiting during overcurrent events and voltage clamping during overvoltage events. Raychem said this single-device approach to coordinated circuit protection helps reduce component count and improve equipment reliability.

The 2Pro device helps equipment manufacturers comply with UL 60950 and remain operational after specified lightning tests. It also helps equipment comply with surge tests per TIA-968-A, IEC 60950, and ITU-T K.20/K.21. The UL 497A listed protector also helps provide ESD protection.

"The new 2Pro protection device helps meet important performance parameters for cost-sensitive PSTN and VoIP telephony equipment," said Boris Golubovic, global marketing manager for Raychem. "Additionally, this solution helps improve network reliability, reduce maintenance and repair costs, and enhance user-satisfaction with customer premise equipment."

The 2Pro overcurrent/overvoltage protection device is available in tape and reel packaging for compatibility with high-volume manufacturing.
