The D3V3Z1BD2CSP is an extremely low capacitance of 0.3 pF ESD protection device designed specifically to protect high-speed differential lines. These devices can also be used for EOS protection due to their high peak pulse current capability (10.5A, tP = 8/20µs). It has excellent ESD protection features, highlighted by low peak ESD clamping voltage and high ESD withstand voltage (+/-20kV contacts per IEC 61000-4-2). The small package DSN 0.60 x 0.30 x 0.30 gives designers the flexibility to protect a single line in applications.
