SCOTTSDALE DIVISION
SRLC05, e3
Low Capacitance TVSarray ™
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 61000–4-2 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.

Note: Transient Voltage Suppressor (TVS) product is normally selected based on its stand off voltage V_WM. Product selected voltage should be
equal to or greater than the continuous peak operating voltage of the circuit to be protected.
