Overview

The PESD2CANFD27U-TR is a high-performance double bidirectional ElectroStatic Discharge (ESD) protection diode housed in a small SOT23 surface-mount package. Specifically engineered to protect two automotive In-Vehicle Network (IVN) bus lines from damage caused by ESD and other transients, it is fully AEC-Q101 qualified for harsh environments.

Why Choose This Part

This device features a low capacitance of 3.1pF at 1MHz, ensuring excellent signal integrity for high-speed data protocols like CAN-FD. It offers a high reverse standoff voltage of 27V and is AEC-Q101 qualified to operate in temperatures ranging from -55 to 150 degrees Celsius.

Applications

CAN-FD and CAN Bus
Protects differential signal lines in high-speed CAN and CAN Flexible Data-rate systems against transient spikes.
FlexRay Interfaces
Secures high-speed deterministic automotive communication networks from electrostatic discharge up to 150 degrees C.
SENT Protocol Protection
Provides robust transient voltage suppression for Single Edge Nibble Transmission sensor interfaces.
Industrial Control Networks
Utilized in industrial automation environments where 24V nominal systems require 27V reverse standoff protection.
