ULN2003ALM/TR 产品概述 — HGSEMI(华冠)

一、产品简介

ULN2003ALM/TR 是华冠(HGSEMI)推出的七路达林顿晶体管阵列,集射极击穿电压(Vceo)为 50V,每一路集电极电流最大可达 500mA。器件集成了基极限流电阻,适合直接与低电压逻辑(如 MCU、TTL/CMOS)驱动接口,采用 SOP-16 封装,TR 表示卷盘包装(Tape & Reel),便于贴片自动化装配。工作温度范围为 -40℃ 至 +85℃。

二、主要性能参数

  • 通道数:7 路达林顿晶体管
  • 集射极击穿电压(Vceo):50V
  • 集电极电流(Ic,单路最大):500mA
  • 最大输入电压(VI):30V
  • 工作温度:-40℃ ~ +85℃
  • 封装:SOP-16(贴片,TR 为卷装供料)

三、功能特点

  • 七路并行独立驱动,便于一次性控制多路负载。
  • 内置基极限流电阻,输入端可直接连接微控制器输出,无需外部限流器件。
  • 对感性负载(继电器线圈、步进电机、阀等)建议配合续流二极管或使用带公共续流管脚的版本,以抑制反向电压尖峰。
  • 标准工业温度范围,适合常见嵌入式与工业控制场景。
  • SOP-16 封装兼顾可焊性与散热面积,适合表面贴装生产。

四、典型应用场景

  • 继电器、继电器阵列驱动。
  • 步进电机、直流电机驱动与分段控制。
  • 阀门、执行器、舵机等系统的开关控制。
  • 指示灯组、LED 矩阵的高电流驱动。
  • 与单片机、PLC、工业控制器的电平隔离与电流放大接口。

五、使用建议与注意事项

  • 单路连续电流不得超过 500mA,若需更大电流应采用并联多通道并注意电流均分与散热。
  • 为保护达林顿对感性负载的高反向电压,若器件本身未集成共阳续流二极管,应在负载侧并联续流二极管或在电源侧采用吸收元件。
  • PCB 布局时应保证集电极走线短且粗,必要时增加散热铜箔和过孔以改善导热。
  • 输入端与逻辑地之间应有合适的旁路电容和去耦设计,避免瞬态干扰引起误触发。
  • 在高占空或高电流工况下注意器件结温,必要时评估散热片或风冷措施。

六、封装与采购信息

  • 封装形式:SOP-16,适配常见贴片生产工艺。
  • 供货形式:TR(Tape & Reel),便于 SMT 线上贴片与回流焊流程。
  • 品牌:HGSEMI(华冠),建议向官方与授权分销渠道获取器件以保证品质与一致性。

ULN2003ALM/TR 以其集成化、驱动能力强和易于与逻辑电平直接接口的特点,适合多路中低压大电流负载控制的场景。在设计时结合热管理与抑制反向尖峰的措施,可获得可靠稳定的驱动性能。若需详细电气特性曲线和典型应用电路,建议参考厂商完整数据手册或联系华冠技术支持获取应用指导。

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
