Overview

The PESD2CAN24XLT-QR is a dual-channel bidirectional TVS diode array specifically engineered to protect CAN bus lines from electrostatic discharge (ESD) and surge events. It features a 24V reverse standoff voltage and a typical clamping voltage of 33V, making it suitable for 24V systems commonly found in commercial vehicles and industrial automation.

Why Choose This Part

This device offers a high peak pulse current robustness of 12A (8/20us) while maintaining a low typical capacitance of 31pF to ensure signal integrity on high-speed data lines. Its AEC-Q101 qualification and operating temperature range of -55 to 150 degrees Celsius make it highly reliable for harsh automotive environments.

Applications

Getting Started

When designing the PCB, place the SOT-23 package as close as possible to the CAN connector to minimize the path length of transient currents. Ensure the ground pin is connected to a solid ground plane with low-impedance vias to maximize the effectiveness of the ESD protection.
