TVS Diode Arrays (SPA® Diodes) Diodes) General Purpose ESD Protection - SM24CANA SM24CANA Series 200W TVS Diode Array RoHS Pb GREEN Description The SM24CANA TVS Diode Array is designed to protect automotive Controller Area Network (CAN) lines from damage due to electrostatic discharge (ESD), electrical fast transient (EFT), and other overvoltage transients. The SM24CANA Series can absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard without performance degradation and safely dissipate 3A of 8/20s surge current (IEC61000-45) with very low clamping voltages. Pinout and Functional Block Diagram 2 Features 1 • ESD, IEC61000-4-2, ±24kV contact, ±30kV air • Low clamping voltage • EFT, IEC61000-4-4, 50A (5/50ns) • AEC-Q101 qualified • Lightning, IEC61000-4-5, 3A (tp=8/20μs) Applications 3 • CAN Bus Protection • Automotive Applications Life Support Note: Not Intended for Use in Life Support or Life Saving Applications The products shown herein are not designed for use in life sustaining or life saving applications unless otherwise expressly indicated. © 2014 Littelfuse, Inc.
