产品概述：ULN2003ADR2G

基本信息 ULN2003ADR2G 是一款高性能的七路 NPN 达林顿晶体管阵列，封装采用 SOIC-16 类型，适合表面贴装。该器件由 ON Semiconductor（安森美）制造，具有出色的电流和电压处理能力，非常适合用于各种低到中等功率的开关应用。

主要特性

  • 晶体管类型：ULN2003ADR2G 是一种 NPN 达林顿配置的晶体管阵列，每个通道均为达林顿配置，能够提供非常高的电流增益，增强了其在低输入电流下驱动高负载电流的能力。
  • 电流处理能力：其最大集电极电流 (Ic) 为 500 mA，使得该器件能够驱动较大负载，适合电机驱动、继电器操作及其他功率控制应用。
  • 电压耐受能力：最大集射极击穿电压 (Vce) 是 50V，这使得该器件在较高工作电压下仍能保持稳定，适应更多的应用场景。
  • Vce 饱和压降：在大约 500µA 与 350mA 的不同条件下，Vce 饱和压降最大为 1.6V，这个特性使得在驱动应用时能效更高，热损耗更小。
  • 低截止电流：在集电极截止时，最大电流为 50µA，表明该器件在关闭状态下的漏电流非常微小，提高了电路的稳定性。
  • 直流电流增益：在特定工作条件下，DC 电流增益 (hFE) 的最小值为 1000 @ 350mA 和 2V，这意味着小的输入信号即可控制较大的输出负载，增强了其应用的灵活性。

应用场景 ULN2003ADR2G 适用于各种电气控制系统中，尤其是在以下领域表现优异：

  1. 电机驱动：用于步进电机和伺服电机驱动，能够提供必要的电流和电压支持。
  2. 继电器控制：可用于驱动机械继电器，选择合适的控制信号来开关高功率电路。
  3. 灯光和LED控制：适用于大功率LED及灯具的控制，实现各种照明应用。
  4. 自动化设备：适合在工业自动化控制系统中，提供可靠的驱动和控制信号。

工作温度范围 ULN2003ADR2G 的工作温度范围为 -20°C 至 85°C，确保其在各种环境下的稳定性，适应不同的工业和商业电路应用场合。

封装与易用性 该产品的 SOIC-16 封装设计使得其在布局及焊接时十分方便，适合在高密度的电路板中使用。此外，该器件可以通过标准方法进行热管理，确保在制定边界条件下的可靠性。同时，达林顿晶体管阵列的多个通道设计，进一步提高了电路设计的灵活性，使得开发者更易于实现集成应用。

总结 ULN2003ADR2G 凭借其高性能的电流增益、宽广的电压和电流处理能力，及低功耗运行的特性，成为了各种现代电子控制系统的理想选择。无论是在工业自动化、电机驱动还是其他高电流需求的应用场合，该器件均表现出色，值得设计师和工程师广泛考虑与应用。对于希望在控制多通道负载和实现高效电源管理的设计者而言，ULN2003ADR2G 是一个可靠的解决方案。

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
