The STMicroelectronics ESD series is a s a bidirectional single line TVS diode designed to protect the data line or other I/O ports against ESD transients. The device is ideal for applications where reduced line capacitance and board space saving are required

Extra low diode capacitance: 0.13 pF
Bidirectional device, 2 lines in 0201
Low leakage current
ECOPACK2 compliant component
Complies with IEC 61000-4-2 level 4
