概述
Description
PESD2CANFD24LT-QR is a two-channel ESD protection diode array designed for CAN and CAN-FD transceivers. It protects the CAN High and CAN Low lines from electrostatic discharge and surges while keeping signal integrity thanks to very low input capacitance and bidirectional protection. The device targets CAN/CAN-FD automotive nets with about a 24 V working/standoff voltage, suitable for 12/24 V systems, and clamps fast pulses per IEC 61000-4-2. The LT suffix indicates lead-free packaging; QR denotes tape-and-reel packaging for automated assembly. Typical uses include automotive ECUs, gateways, and body controllers that employ CAN or CAN-FD. Benefits: rugged ESD protection with minimal impact on signaling, compact footprint, easy integration with standard CAN transceivers. For exact electrical specs, pinout, and packaging details, consult the manufacturer’s datasheet.
