ESD protection for automotive networks

A range of high-performance ESD protection diodes that is ideal for automotive

As the amount of in-car electronics increases, ESD is becoming a real challenge for automotive systems designers. Failures in electronic control units (ECUs) due to transient pulses not only damage the maker's reputation, they put lives at risk. We offer a range of high-performance ESD protection diodes ideally suited to automotive use, helping you improve the reliability of your complete system.

Key benefits

• Outstanding size / performance ratio
• Optimal electromagnetic immunity (EMI)
• Dedicated types for CAN and LIN systems
• Compact, industry-standard SOT23 and SOD323 (SC-76) packages

Key features

• Excellent ESD clamping performance
• Ultra low leakage current and low device capacitance
• ESD protection up to 23 kV
• IEC 61000-4-2, level 4–compliant (8 kV contact, 15 kV air discharge)
• Optimized diode structure

Key applications

• Protecting ECUs such as CAN and LIN transceivers from damage due to ESD and other transient pulses
• Data and audio interfaces e.g. car multimedia
• Over-voltage protection e.g. airbag controllers
• Car-driver interface protection e.g. dashboard panels

Descriptive summary

You can use our solutions to protect LIN (Local Interconnect Network) bus transceivers, CAN (Controller Area Network) bus transceivers and other ESD–sensitive automotive electronic components.
