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,
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.
