Revised: JC.01/05/21
Description
Applications
The AQ24CANFD 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 AQ24CANFD can absorb repetitive ESD strikes
above the maximum level specified in the IEC 61000-4-2
international standard without performance degradation
and can safely withstand 3A surge (8/20μs waveshape as
defined in IEC 61000-4-5 2nd edition) at a very low clamping
voltages.
Features
• ESD, IEC 61000-4-2,
±21kV contact, ±21kV air
• EFT, IEC 61000-4-4, 50A
(5/50ns)
• Lightning, IEC 61000-4-5
2nd edition, 3A (8/20μs)
• PPAP capable
• ESD, ISO 10605, 330pF
330Ω, ±21kV contact,
±21kV air
• Low clamping voltage
• Low leakage current
• AEC-Q101 qualified
• Moisture Sensitivity Level
(MSL -1)
• Halogen free, lead free
and RoHS compliant
• CAN Bus Protection
• Automotive Applications
• Electronic Control Units
• Body Control Units
• ADAS Control Units
• PowerTrain Control Units
• Factory Automation
• Lightning Control (DALI)
