This product is a TVS diode array manufactured by Semtech. It has high surge capability, low operating voltage and fast response time. It is ideal for use as board level protection of sensitive semiconductor components.
The SM series of transient voltage suppressors (TVS) from Semtech protect data and transmission lines from ESD, EFT and lightning surges. The dual‑junction common‑anode design allows protection of one bidirectional line or two unidirectional lines, and the low‑profile SOT‑23 package fits crowded board layouts.
The document provides absolute maximum ratings, electrical characteristics for each voltage rating (SM05, SM12, SM15, SM24, SM36), typical performance curves, layout recommendations, mechanical dimensions, marking codes, ordering information and contact details for Semtech’s Protection Products Division.
