Description

RClamp1631PQ and RClamp2831PQ are low capacitance

RailClamp TVS for ESD and EOS protection of high-speed

interfaces in automotive applications. They are designed

to provide minimal capacitive loading and low-harmonic

generation on RF antenna lines.

These devices incorporate low clamping voltage and

asymmetric trigger-voltages providing protection for RF

pins which pass both DC input voltages and AC output

signal voltages. ESD protection characteristics are

highlighted by low typical dynamic resistance, low peak

ESD clamping voltage, and high ESD withstand voltage

(±30kV contact per IEC 61000-4-2). Each device will

protect one high-speed data line operating at 16V or 28V

and will withstand short-to-battery fault conditions in

12V and 24V systems without damage. These devices are

qualified to AEC-Q100 (Grade 1) and AEC-Q101 .
