1N4004 产品概述
1. 基本信息
1N4004 是一款通用二极管，采用 DO-41 封装，具有良好的耐压和电流承载能力。该元器件的主要参数包括：正向电压降约为 1V，最大反向重复电压（V_RRM）为 400V，我能承载的最大直流电流（I_F）为 1A。这使得 1N4004 成为各种电子电路和设备中广泛使用的元器件，适合于整流、电压钳位和信号处理等应用。
2. 封装与特性
1N4004 采用的 DO-41 封装是一个标准的玻璃封装，外形小巧，适合于大规模生产和设备的紧凑设计。该封装不仅具有良好的机械强度，而且可以有效散热，对于高频应用和高温环境下的使用具有优势。它的设计使得二极管能够在更高的温度和更恶劣的环境中保持稳定工作性能。
3. 电气特性
1N4004 的正向电压降约为 1V，虽然相对较高，但在众多应用场景中仍然可以接受。特别是在整流电路中，由于其耐压高达 400V，它可以处理来自交流电源的高峰值电压，因此适用于各种市电供电的电子设备。此外，1N4004 的正向电流为 1A，使其能够满足大多数家用电器和小型电子设备的需求。
4. 应用场景
1N4004 的应用非常广泛，主要包括以下几个方面：
电源整流：在各种电源适配器和充电器中，1N4004 可以作为整流二极管，将交流电转化为直流电，供给电子设备使用。由于其高压承受能力，它特别适用于市电整流。
电压保护：在电路中作为钳位二极管使用，可以保护敏感组件免受过电压或尖峰电压的影响。例如，在某些开关电源中，1N4004 可以防止电源关断时产生的反向电动势对电路造成损伤。
信号检测：在一些信号处理电路中，1N4004 可用于解调和整流信号，如当接收到AC信号时，通过1N4004 进行整流，提取出信号的直流成分，供后续电路分析。
5. 选型与替代
1N4004 作为一款经典的通用二极管，其使用非常普遍。在选型时，工程师需要考虑电压、电流和封装等参数。1N4004 也有它的替代品，如 1N4001、1N4002 和 1N4003，虽然它们的参数相似，但最大反向电压有所不同，选择时应根据具体需求进行选择。
6. 结论
总之，1N4004 是一款性能稳定的通用二极管，适合广泛的应用场景，特别是在需要高额定电压和电流的情况下。其简单易用的特点，使其成为了电子设计中不可或缺的基本元件。在现代电子产品设计中，1N4004 的结合性和可靠性使其成为一个理想选择，尤其在电源管理和信号处理等应用上，被广泛采用。了解和掌握1N4004的特性及其应用，对于设计电子电路的工程师至关重要。
Request for quote

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
