PROTECTION PRODUCTS
Description
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.
