1N4004-E3/54 产品概述
一、产品概况
VISHAY（威世）1N4004-E3/54 是一款通用整流二极管，采用 DO-41 玻璃环或塑封轴向封装，面向一般电源整流和保护用途。该器件为无铅（E3）版本，符合 RoHS 要求，适用于工业及消费类电子设备的直流整流、反向保护与续流回路。
二、主要电气参数
- 正向压降：Vf = 1.1V（在 If = 1A 条件下）
- 直流反向耐压：Vr = 400V（重复峰值反向电压）
- 平均整流电流：Io = 1A
- 反向电流：Ir = 5μA（在额定条件下为典型值）
- 非重复峰值浪涌电流：Ifsm = 30A（单周期冲击）
- 工作结温范围：-50℃ ～ +150℃
三、关键特性与优势
- 耐压高、耐浪涌能力强：400V 的反向耐压配合 30A 的冲击承受能力，能应对启动瞬态与负载冲击。
- 低漏电流：5μA 级别的反向电流，在高阻抗和低功耗场合表现良好。
- 宽温度适应性：-50℃ 至 +150℃ 的结温范围，适用于多种工作环境。
- 标准化封装与兼容性：DO-41 轴向封装便于波峰/回流焊后手工或自动化装配，且兼容常见 1N400x 系列替换。
四、典型应用场景
- 开关电源与线性电源的整流桥或单只整流元件。
- 二极管保护、极性防护与反接保护电路。
- 马达驱动、继电器线圈续流保护以及整机电源滤波回路。
- 家用电器、照明与工业控制设备中的通用整流需求。
五、封装与可靠性
DO-41 轴向封装利于散热并保持机械强度。E3 标识表明为无铅环保版本（符合 RoHS），适合现代生产工艺。器件在设计时考虑了长期温度循环与冲击能力，适合连续工作和周期性启动场合。
六、选型与使用建议
- 若工作电流长期接近 1A，应做好散热设计，尽量缩短导线与焊盘路径以降低热阻。
- 在高浪涌场合（如感性负载）建议增加吸收元件或选择更高 Ifsm 的型号。
- 对温度敏感的应用注意结温监控，必要时在器件附近留出散热空间或加装散热片。
- 出于可靠性考虑，批量采购时核对 E3/54 的包装与出货合规信息，保证一致性。
此器件为成熟可靠的通用整流二极管，适合替代或作为标准整流元件在多种电源与保护电路中使用。

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.
