TJA1057GTK/3Z 产品概述

一、概述

TJA1057GTK/3Z 是恩智浦(NXP)面向汽车及工业应用的半双工 CAN 收发器,适用于高速 CAN 总线环境。器件支持高达 5 Mbps 的数据速率,工作在标准 5V 电源下,结合宽温和高耐受封装,专为严苛电磁与热环境设计,适合 ECU、车身控制模块、动力总成及工业控制节点等场景。

二、主要电气参数(关键值)

  • 数据速率:最大 5 Mbps
  • 工作电压:4.75 V ~ 5.25 V(典型 5 V)
  • 工作电流:典型 70 mA(正常工作)
  • 静态/待机电流:1.2 mA(低功耗待机)
  • 工作温度范围:-40 ℃ ~ +150 ℃
  • 封装:HVSON-8-EP(3 × 3 mm,带散热焊盘)
    这些参数体现出器件在高频通信、低静态功耗与高温环境下的平衡性能。

三、功能特点与优势

  • 支持高速 CAN(高达 5 Mbps),满足实时控制与诊断通信需求。
  • 宽温等级(最高 +150 ℃),适配动力系统与高温环境应用。
  • 低待机电流设计,有助于车辆或系统在休眠阶段降低功耗。
  • HVSON-8 带暴露焊盘(EP),实现更佳的散热性能与可靠的 PCB 焊接机械强度,节省 PCB 面积。
  • 典型 CAN 收发器的实用保护特性(如总线故障容错、短路/过温保护、ESD 抗扰能力)配合外部防护器件可构建高可靠总线节点。

四、典型应用场景

  • 汽车电子:发动机/变速箱 ECU、车身控制模块、座椅/车门控制单元、ADAS 辅助子系统。
  • 工业控制:现场总线节点、过程控制设备、工业网关。
  • 其他对抗电磁、温度要求高的分布式控制与诊断网络。

五、PCB 布局与使用建议

  • 电源去耦:VCC 旁靠近器件布置 0.1 μF 与 1 μF 陶瓷去耦电容以抑制高频噪声并稳定电压。
  • 暴露焊盘(EP)应焊接到 PCB 地铜,加入多孔散热过孔(thermal vias)以提升热耗散能力,考虑器件在 5 V/70 mA 工作下约 0.35 W 的耗散(P≈V×I)。
  • 总线端采用 120 Ω 终端电阻(或分割终端 2×60 Ω + 中点电容)以控制反射与共模滤波;建议在总线进线处配合共模扼流圈与 TVS 做 EMC/浪涌防护。
  • 为提高稳健性,布线尽量缩短 CAN_H/CAN_L 到收发器的差分线长度并保持差分对阻抗一致。

六、可靠性与设计注意

  • 在高温与长寿命应用中,应保证良好散热路径与可靠焊接工艺,暴露焊盘的焊点完整性影响热阻与可靠性。
  • 外部防护(TVS、短路限流器、过压抑制)可增强系统对瞬态、电磁干扰和线缆故障的鲁棒性。
  • 在系统验证阶段进行总线电磁兼容(EMC)与热循环测试,确保在目标应用温度和负载下稳定通信。

总结:TJA1057GTK/3Z 以其 5 Mbps 的高速能力、5 V 工作电源兼容、低待机电流与 HVSON-8 小型高散热封装为特色,适合需要高可靠、高温耐受与紧凑封装的汽车及工业 CAN 总线节点设计。在实际设计中,配合妥善的 PCB 散热、去耦与总线防护措施可以发挥其最佳性能。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
