Description
Applications
The AQ24CANA 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 AQ24CANA can absorb repetitive ESD strikes above
the maximum level specified in IEC 61000-4-2 international
standard without performance degradation and safely
dissipate 5A of 8/20µs surge current (IEC 61000-4-5 2nd
Edition) with very low clamping voltages.
Features
• ESD, IEC 61000-4-2,
±27kV contact, ±30kV air

(5/50ns)
• Lightning, 5A (8/20µs as
defined in IEC 61000-4-5
2nd Edition)
• PPAP capable
• Low clamping voltage
• Low leakage current
• ESD, ISO 10605, 330pF
330Ω, ±27kV contact,
±30kV air
• AEC-Q101 qualified
• Halogen-Free, Lead-Free
and RoHS-Compliant
• Moisture Sensitivity
Level(MSL -1)
• Automotive Applications
