TJA1462AT/0Z 是恩智浦(NXP)面向高速 CAN-FD 总线的半双工收发器解决方案,封装为 SOIC-8。器件支持高达 8 Mbps 的数据速率,工作电压范围为 4.5 V ~ 5.5 V,静态或待机电流极低(约 2 μA),工作电流典型值约 70 mA,工作温度范围宽(-40 ℃ ~ +150 ℃),适合在汽车及工业等苛刻环境中使用。
以上参数适合需要高带宽、低待机功耗及宽温区可靠性的车规级或工业通信节点。
TJA1462AT/0Z 作为 CAN-FD 收发器,其关键优势在于支持更高的数据吞吐(相较经典 CAN),并在待机状态下保持极低功耗。典型应用包括:
器件宽温特性和低待机电流使其特别适合需要长期通电或节能的系统设计。
TJA1462AT/0Z 为 SOIC-8 小型封装,便于在标准双列直插或自动插件工艺中使用。器件工作温度上限 +150 ℃ 表明其经过高温等级设计或适配车规级应用,但具体可靠性指标(如抗静电、短路及瞬态抑制能力)应以官方数据手册为准。在高温或高振动环境下,建议按照制造商推荐的焊接与热循环规范进行装配和测试。
为确保收发器稳定工作,建议在 PCB 设计与系统集成时注意以下几点:
具体引脚连接与终端阻抗值,请参考 NXP 官方数据手册。
在选择 TJA1462AT/0Z 时,应确认系统对 8 Mbps 数据率、5 V 电源兼容性以及高温工作能力的需求。若系统需要更低工作电流或更高总线速率,或需特定的故障诊断输出与保护特性,应对照数据手册比较其他型号或厂商的产品。最终选型建议基于完整的数据手册、电磁兼容(EMC)和可靠性测试结果。
总结:TJA1462AT/0Z 提供了面向汽车与工业级应用的高数据率 CAN-FD 收发能力、低待机功耗与宽温工作范围,是要求稳定高速差分通信且需耐高温环境的优选器件。有关详细电气特性和应用范例,请参阅 NXP 官方资料与参考设计。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
