SM12/SM15

Low Capacitance Dual Line ESD Protection Diode Array

SM12/SM15 SOT23-3

General Description

The SM12/SM15 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 SOT23-3 package

allows flexibility in the design of “crowded” circuit boards. The SM12/SM15 will meet the surge

requirements of IEC 61000-4-2 (Formerly IEC801-2), Level 4, “Human Body Model” for air and

contact discharge.
