SIT82C251T 是芯力特(SIT)推出的一款高性能 CAN 总线收发器,采用 SOP-8(150 mil)封装,面向汽车电子与工业控制等差分总线通信场景。器件支持最高 1 Mbps 的数据速率,工作电压范围为 4.5V 到 5.5V,工作电流典型值 70 mA,静态(待机)电流仅 12 µA,且工作温度覆盖 -40 ℃ 至 +125 ℃,适用于恶劣环境下长期可靠运行。
该器件将 MCU/控制器的单端串行信号(TXD/RXD)与 CAN 差分总线(CANH/CANL)进行物理层转换,具备低功耗待机能力与高速数据传输能力,适合集成到车载电子控制单元(ECU)、网关、传感器节点、工业现场总线接口等应用中。
SIT82C251T 提供标准 8 引脚 SOP-8 形式封装(150 mil 间距),常见功能引脚包含 VCC、GND、TXD、RXD、CANH、CANL 与控制/模式引脚(如 STB/RS / EN 等)。具体的引脚排列及功能、电气时序请以官方数据手册为准,在产品选型与线路设计时应参照原厂资料进行布线与驱动逻辑配置。
SIT82C251T 的工作温度覆盖汽车级要求,适合严苛温度与振动环境。但在实际应用中仍需注意:
在最终设计与大量生产前,建议获取并仔细阅读 SIT 官网或经销商提供的完整数据手册、器件规范书与封装图纸,并联系供应商确认库存与后续供货稳定性。若需针对特定应用(如高耐压、增强 ESD 或功能安全要求)进行选型或评估,可与厂商工程支持沟通获取更详细的应用建议与测试数据。

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.
