General Description
The SM05 of transient voltage suppressors (TVS) are designed to protect components which are connected to data and transmission lines from voltage surges caused by electrostatic discharge (ESD). 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 dual-junction common-anode design allows the user to protect one bidirectional data line or two unidirectional lines. The low profile SOT23 package allows flexibility in the design of “crowded” circuit boards. The SM05 will meet the surge requirements of IEC 61000-4-2 (Formerly IEC801-2), Level 4, “Human Body Model” for air and contact discharge.
