低电容TVSarray Low Capacitance TVSarray

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 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.
