The SMS12C series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD and other voltage-induced transient events. Each device will protect up to five lines. They are available with operating voltages of 12V. They are unidirectional devices and may be used on lines where the signal polarities are above ground.TVS diodes are solid-state devices designed specifically for transient suppression. They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage and no device degradation.The SMS series devices may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The low cost S0T23-6L package makes them ideal for use in portable electronics such as cell phones, PDA's, and notebook computers.
