Low Capacitance TVSarray 鈩?/div>
DESCRIPTION
This TRANSIENT VOLTAGE SUPPRESSOR (TVS) is packaged in an
SOT-143 configuration with very low capacitance giving protection for two high
speed data lines connected to terminals 2 and 3. This protection is from
electrostatic discharge (ESD) and other induced voltage surges such as electrical
fast transient/burst (EFT) that can damage or upset sensitive circuitry as defined in
IEC 61000鈥?-2 and IEC 61000-4-4. With its four steering diodes and one TVS,
any positive voltage on the data lines exceeding one diode voltage drop above the
positive voltage supply line (Vcc) connected to terminal 4 will be diverted away
from the protected line to the supply line. If this also exceeds the TVS voltage, the
surge is directed to ground (Gnd) at terminal 1. Negative voltages greater than one
voltage drop are diverted to ground. This SRLC05 can also serve as a bi-
directional, low capacitance TVS when simply using terminals 2 and 3. In a similar
configuration, the terminal 1 can optionally be tied to ground.
