Revision 07/12/04

The SM series 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),

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 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 SM series will meet the surge requirements of IEC

61000-4-2 (Formerly IEC 801-2), Level 4, “Human

Body Model” for air and contact discharge.
