ULN2003AIDR 是由德州仪器(Texas Instruments)推出的一款高效 NPN 达林顿型晶体管阵列。它专为驱动较大电流负载而设计,能够快速开关,广泛应用于汽车、工业自动化、家用电器等多个领域。对于需要控制电机、继电器和其他高电流负载的设计,ULN2003AIDR 提供了一个理想的解决方案。
ULN2003AIDR 是一款具有七个独立 NPN 达林顿输出的晶体管阵列,采用 16-SOIC 表面贴装封装,适合对空间要求严格的电子设备。其主要参数如下:
ULN2003AIDR 的输入是反相的,意味着输入信号为高电平时,输出将为低电平,这种特性使得它与多种控制器兼容。每个输出通道为低端输出配置,可以与多个负载并联工作,根据具体设计需要来灵活配置。其输入-输出比为 1:1,简化了设计和使用。
由于其高电流驱动能力和宽工作温度范围,ULN2003AIDR 适用于以下应用场合:
ULN2003AIDR 采用 16-SOIC 表面贴装封装,尺寸为 0.154"(3.90mm 宽)。该封装形式便于自动化生产和贴片,同时节省了电路板空间,适用于现代电子设备的高密度设计要求。
ULN2003AIDR 具有广泛的兼容性,常用于与微控制器(如 Arduino、PIC、AVR、或基于 ARM 的微处理器)接口,形成高效的控制方案。此外,基于其反相输入特性,可直接与典型的逻辑电平信号(例如 TTL、CMOS 逻辑)配合使用,简化了与各种逻辑电路的集成。
ULN2003AIDR 是一款功能全面、效率高、可靠性强的 NPN 达林顿晶体管阵列,适合多种电力驱动应用。其设计精良,能够在各种恶劣环境下稳定工作,使其成为工业、汽车及消费电子设备的理想选择。无论是作为功率开关、电机驱动,还是其他高电流应用,ULN2003AIDR 都能提供出色的性能,值得工程师在设计中考虑。

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
