SEMTECH  SM12  TVS二极管, TVS, SM系列, 双向, 12 V, 19 V, SOT-23, 3 引脚

The SM series TVS Diode Array 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. It is 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 dual-junction common-anode design allows the user to protect one bidirectional data line or two unidirectional lines. It will meet the surge requirements of IEC 61000-4-2 Formerly IEC 801-2, level 4 and Human Body Model for air and contact discharge.
