1N4004 是一款通用整流二极管,华轩阳电子(HXY MOSFET)提供的独立式 SMA 封装版本,面向交流整流、反向保护和一般电源整流应用。该器件在 1A 持续整流电流下正向压降约为 1V(1A 测试条件),具有 400V 的直流反向耐压能力,能够满足大多数低功率到中等功率电源电路的需求。
SMA 封装体积小、热容量有限。设计时应注意:
在批量使用前,应依据实际工况关注以下项目:
总结:1N4004(SMA,华轩阳电子)是一款面向通用整流与保护用途的价廉且可靠的二极管,适用于需要 400V 阻断和约 1A 工作电流的场合。合理的散热设计、浪涌管理与适当的裕量选型能够确保在实际应用中的稳定与长寿命。若有更严格的正向压降或更高持续电流需求,可据此条件选择更合适的替代器件。

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.
