Description

RailClamp® TVS diodes are designed to protect sensitive

electronics from damage or latch-up due to ESD &

EOS. These devices offer desirable characteristics for

board level protection including fast response time,

low operating and clamping voltage, and no device

degradation.

The RClamp®1221PW features extremely good ESD

protection characteristics highlighted by low typical

dynamic resistance, low peak ESD clamping voltage,

and high ESD withstand voltage (±10kV contact per IEC

61000-4-2). Low maximum capacitance (0.45pF at

VR= 0V) minimizes loading on sensitive circuits. Each

device will protect one high-speed data line operating at

12 Volts.

This device is in a 2-pin DFN 1.0 x 0.6 x 0.55mm 2-Lead

package. The small package gives the designer the

flexibility to protect single lines in applications where

arrays are not practical. The combination of small size

and high ESD surge capability makes them ideal for use

in portable applications.
