Semtech Corporation, a supplier of analog and mixed-signal semiconductors, has announced the release of the TClamp1202P, the smallest low-cap, high-surge, 12V (Vrwm) transient voltage protection array in its class.
Offering 100A (8×20µs waveform) of surge immunity in an ultra-small 2mm x 2mm package, the TClamp1202P can be used in a wide range of industrial and telecommunications applications to safeguard sensitive communications transceivers from electrostatic discharge (ESD), electrical fast transients (EFT), cable discharge and lightning surge transients.
The two-line TClamp1202P delivers optimal transient protection, featuring a very low clamping voltage and a line-to-line capacitance of less than 12pF. The part’s robust (100A, tp=8/20μs) surge rating for high-surge lightning protection meets the industry’s most stringent telecommunications and industrial surge requirements. Additionally, the flow-through layout of the part enhances signal quality and design flexibility.
“With increased deployment of RS-485 interfaces into outdoor and high-surge environments, high-surge, low-clamping transient voltage protection is critical. We have already seen very good adoption of this part from key market leaders,” Rick Hansen, product marketing director for Semtech’s protection products division, said. “The TClamp1202P offers some unique advantages to safeguarding RS-485-based systems from the harsh overvoltage threats common on these ports.”
