Overview

The PESD2CANFD54VT-QR is a high-performance double ESD protection device designed specifically for CAN, CAN-FD, and FlexRay interfaces. Housed in a SOT23 package, it features a 54V reverse standoff voltage making it ideal for 48V automotive board nets. It offers a very low capacitance of 3.1pF to ensure signal integrity at high data rates.

Why Choose This Part

This device is AEC-Q101 qualified and compliant with ISO 7637-2 pulse standards for automotive transients. Its 54V standoff voltage provides significant headroom for 48V systems, while the ultra-low 3.1pF capacitance minimizes signal distortion on high-speed differential pairs.

Applications

48V Automotive Board Nets
Protection for CAN and CAN-FD lines in mild hybrid and electric vehicles where high voltage tolerance is required.
FlexRay Interfaces
Low capacitance characteristics support the high-speed timing requirements of FlexRay communication protocols.
SENT Protocol Protection
Protects Single Edge Nibble Transmission (SENT) sensor lines from ESD strikes and transient surges.
Industrial Networking
Robust transient protection for 24V or higher industrial control networks subject to harsh electrical environments.

Getting Started

Integrate this component as close to the CAN connector as possible on the PCB to minimize lead inductance. Ensure the common pin (pin 3) is connected to a solid ground plane for effective transient dissipation. Refer to Nexperia's layout guidelines for high-speed differential signal protection to maintain CAN-FD signal integrity.
