ULN2003ACM/TR 产品概述

一、产品简介

ULN2003ACM/TR 是一款七路达林顿晶体管阵列,适用于将低电平逻辑信号直接驱动中小功率负载。产品由 HGSEMI(华冠)生产,封装为 SOP-16(CM代表塑封,TR代表卷带包装)。典型应用包括继电器、电磁阀、小直流电机、继电器阵列、指示灯和步进电机驱动等。

二、主要电气参数

  • 通道数:7 路达林顿对
  • 集射极击穿电压(Vceo):50 V
  • 单通道集电极电流(Ic):500 mA(连续额定,受封装与散热限制)
  • 最大输入电压(VI):30 V
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 输入电流(ON):0.93 mA(典型)
  • 输入电流(OFF):100 μA(典型)
  • 输入电容(Ci):15 pF(典型)
    这些参数说明器件对逻辑侧的驱动电流要求低、对输入电压容限高,且每路能承受中等电流的下拉驱动能力。

三、产品特性要点

  • 集成达林顿结构:每一路由二级晶体管组成,提供较大的电流放大倍数,便于直接由低电平逻辑(TTL/CMOS/微控制器)驱动。
  • 低输入电流需求:典型 ON 电流约 0.93 mA,降低了对上层驱动器的负担。
  • 内置保护与兼容性:ULN2003 系列通常配备输入限流电阻以及用于感性负载的共用反并联续流通路(请参考实际数据手册确认具体保护结构),可直接驱动继电器和电感性负载。
  • 开关特性:输入电容约 15 pF,影响开关速度,适合多数中低速控制场合;对于高频开关需评估总体延迟与功耗。

四、典型应用场景

  • 继电器和继电器阵列驱动
  • 指示灯、LED 矩阵的低侧开关
  • 小型直流电机与步进电机控制(作为驱动级的下一级)
  • 工业控制板的驱动接口,替代分立晶体管以节省 PCB 区域与设计复杂度
  • 与 MCU、PLC、TTL/CMOS 逻辑直接接口

五、使用与热设计建议

  • 并非所有通道同时满载:尽管单路可达 500 mA,但多路同时工作时封装总功耗与结壳温度会限制实际可持续电流,设计时应按总功耗估算并留余量。
  • 散热措施:在高电流或连续工作情况下,需在 PCB 设计中考虑加大铜箔面积、使用散热通孔或外加散热器以降低结温。
  • 感性负载保护:器件通常对感性负载有内置续流路径,但对高能量脉冲或长时间感性事件,建议在外部增加稳压或能量吸收器件(如 TVS、RC 能量吸收网络)以保护芯片并延长寿命。
  • 驱动器匹配:根据典型输入电流(0.93 mA)选择上级逻辑驱动能力,上级输出应能稳定提供该电流并兼顾高速切换时的瞬态需求。
  • 输入电压限制:输入端最大允许 30 V,请避免超过该值以免损伤输入结构。

六、封装与订购信息

  • 封装:SOP-16(CM)便于表面贴装与自动化生产
  • 包装形式:TR(卷带)适合贴片贴装机直接上料
  • 品牌:HGSEMI(华冠),在可靠性和成本方面通常具有竞争力。
    订购时请关注完整料号(含封装与包装后缀)、批次和器件出货文件(测试报告、RoHS 合规证书及最新数据手册),以确保与设计规格一致。

总结:ULN2003ACM/TR 是一款适合工业控制与消费电子中低速、中功率驱动场合的七路达林顿阵列,具有高电压耐受、低输入驱动要求和方便的 SOP-16 封装。合理的热设计与对感性负载的额外保护,将有助于系统获得更好的稳定性与寿命。若需更详尽的时序、饱和压降曲线或封装机械尺寸,请参阅厂商完整数据手册。

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
