概述

Description

PESD2CANFD24LT-QR is a two-channel ESD protection diode array designed for CAN and CAN-FD bus interfaces in automotive electronics. It protects the CAN_H and CAN_L lines from electrostatic discharges and transients while maintaining low bus capacitance to preserve CAN-FD signal integrity.
Key points:
- 2-channel protection for CAN/CAN-FD networks
- 24V working/bus voltage rating
- Very fast ESD response with low parasitic capacitance
- Automotive-grade protection suitable for ECU, gateway, and body controllers
- LT package with QR (tape-and-reel) packaging for automated assembly
- Easy, compact protection solution placed near the CAN connector or ECU interface
Usage: place the device between CAN_H/CAN_L and ground, close to the transceiver to clamp ESD events and minimize disturbance to normal CAN signaling.

Features

PESD2CANFD24LT-QR features (concise):
- 2-channel ESD protection diode array for CAN and CAN FD bus lines (CANH/CANL)
- 24-V bus-tolerant protection suitable for automotive CAN networks
- Very low line capacitance per channel to minimize signaling impact on high-speed CAN FD
- Bidirectional protection with fast clamping to ground during ESD events
- Robust ESD capability per IEC 61000-4-2 (no external supply required)
- Automotive-grade device, wide operating temperature (-40°C to 125°C)
- RoHS compliant; lead-free
- Package: LT (leadless) in Tape & Reel (QR) packaging
Note: For exact electrical specs (capacitance, clamping voltages, ESD levels) please consult the datasheet.

Package

PESD2CANFD24LT-QR is supplied in a 2‑pin SMD SOD523 (SC‑70) package. The “LT‑QR” denotes tape‑and‑reel packaging for automated assembly (lead‑free).

Pinout

Pin count: 3 pins (SOT‑23 style).
Function (concise): dual‑line low‑capacitance ESD/TVS protector for CAN‑FD bus lines. Pins map typically as:
- Pin 1: CAN_L (I/O 1)
- Pin 2: CAN_H (I/O 2)
- Pin 3: GND
It clamps ESD/transient pulses to protect the CAN_H and CAN_L lines to ground while preserving high‑speed CAN‑FD signaling.

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (originally spun out of NXP) that designs and makes discrete components, logic ICs, MOSFETs and protection devices (including TVS/ESD diodes) for automotive, industrial and consumer markets.

Application

Applications:
- Automotive CAN/CAN FD interfaces and ECUs operating on 24 V networks
- Gateways, body electronics, sensors, actuators, and motor controllers
- Industrial CAN networks (CANopen, CiA) in factory equipment
- Any device needing robust ESD/EFT/surge protection on CAN High/Low lines in 24 V automotive/industrial environments
- QR-packaged for compact PCB mounting
