Semtech's device protects I/o interface from dangerous surges

Semtech has announced TClamp1202P, a transient voltage protection array offering 100A (8x20µs waveform) of surge immunity for wide range of industrial and telecommunications applications for safeguarding sensitive communications transceivers from electrostatic discharge (ESD), electrical fast transients (EFT), cable discharge and lightning surge transients.

TClamp1202P suggested for safeguarding RS-485 interfaces deployed in telecom and industrial applications such as wireless base stations and digital surveillance cameras.

Brief specs:
Transient protection for high-speed data lines to: IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact); IEC 61000-4-4 (EFT) 40A (5/50ns); IEC 61000-4-5 (lightning) 100A (8/20μs)
12V working voltage protection
High surge capability: 100A (tp=8/20μs)
Protects two I/O lines
Low capacitance (
