The PESD1LIN is a high-performance ESD protection diode designed for the automotive LIN communication bus. It features high ESD protection (±30kV), low capacitance, low leakage, fast response, and high reliability. It is ideal for applications requiring stable communication and high noise immunity, such as automotive electronics, body control modules, and industrial communication interfaces.

FEATURES

> Designed specifically for LIN bus protection
Provides robust ESD and transient overvoltage protection in 24V systems without compromising communication signal integrity.

> Ultra-low capacitance & low leakage current
Does not affect LIN bus signal waveforms or transmission rates, ensuring stable and reliable bus communication.

> High ESD immunity
Passes IEC 61000-4-2 ±30kV ESD testing, effectively preventing ESD damage.

> Fast response time (<1ns)
Instantly clamps when an ESD or surge event occurs, protecting the IC and communication transceiver.

> Small surface mount package (SOD-323)
Saving PCB space, suitable for high-density automotive control modules.

High reliability & AEC-Q101 compliant
Suitable for automotive electronics applications, meeting stringent temperature and reliability requirements.

APPLICATIONS

> LIN Bus Protection (Local Interconnect Network)
Protecting LIN communication lines for automotive body communication systems (window, lighting, and air conditioning controls, etc.)

> In-vehicle Communication Interface Protection
Protecting LIN transceivers (such as the TJA1020 and MC33662) from ESD and surge damage

> Industrial Control Systems
Providing ESD and surge protection for industrial fieldbuses (such as RS-485/LIN hybrid interfaces)

> Smart Lighting and HVAC Modules
Protecting communication and control signal lines to improve device anti-interference performance

Microcontroller I/O Port Protection
Protecting MCU communication ports or sensor interfaces from static electricity
