Transient Voltage Suppressors Array for ESD Protection SMDAXXC-8 Series Description SOP-14 The SMDAxxC-8 series of transient voltage suppressors are designed to protect components which are connected to data and transmission lines from voltage surges caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. TVS diodes are characterized by their high surge capability, low operating and clamping voltages, and fast response time. This makes them ideal for use as board level protection of sensitive semiconductor components. The SMDAxxC-8 is designed to provide transient suppression on multiple data lines and I/O ports. The low profile SOP-14 design allows the user to protect up to eight data and I/O lines with one package. They are bidirectional device and may be used on lines where the normal operating voltage is above and below ground (i.e. -12V to +12V).
