TVS Diode Arrays (SPA® Diodes) General Purpose ESD Protection - SM24CANB SM24CANB Series 500W TVS Diode Array RoHS Pb GREEN Description The SM24CANB 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 SM24CANB Series can absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard without performance degradation and safely dissipate 10A of 8/20s surge current (IEC610004-5) with very low clamping voltages.
