1N4007W 产品概述
一、产品简介
1N4007W 是由 DOWO（东沃）推出的一款通用高压整流二极管，采用小型 SOD-123FL 表面贴装封装。器件为单颗独立型二极管，直流反向耐压高达 1kV，整流电流 1A，适用于各种功率供电和高压整流场合。结构紧凑、耐压高、性能稳定，是替代传统轴向 1N4007 的表面贴装升级方案。
二、主要电气参数
- 直流反向耐压 (Vr)：1000 V（典型等级）
- 正向压降 (Vf)：约 1.1 V @ 1 A
- 最大整流电流：1 A（连续正向电流）
- 反向漏电流 (Ir)：约 1 μA（在额定电压下的典型值）
- 非重复峰值浪涌电流 (Ifsm)：30 A（单次浪涌）
- 工作结温范围：-55 ℃ ～ +150 ℃
三、封装与热性能
器件封装为 SOD-123FL，体积小、厚度低，适合自动化贴片回流焊加工。虽为小型封装，但在合理 PCB 散热设计下可满足 1A 连续整流需求。建议在高功率应用中配合加大铜箔面积、增加过孔或散热垫以提高热扩散能力，避免过高结温导致寿命下降。
四、典型应用场景
- 开关电源与高压整流电路的末级整流
- 充电器、适配器、家电中的高压整流与保护
- 反向电压保护、反接防护与续流二极管
- 工业控制、照明电源及其他要求高耐压的小型功率场合
五、设计与使用建议
- 在设计时需考虑正向压降带来的功率损耗（Pd ≈ Vf × If），并据此做好散热设计。
- 高耐压下反向漏流随温度升高会增加，关键电路应在最大工作温度下验证漏电性能。
- 浪涌电流能力为 30A（单次），在重复或长期冲击环境下应评估器件寿命并适当增加保护电路（如浪涌吸收器）。
- SOD-123FL 为 SMD 器件，贴片时按厂家推荐的回流焊工艺曲线操作，避免超温或长时间高温暴露。
六、可靠性与选型注意
1N4007W 工作结温宽、耐压高，适合工业级应用。选型时应确认系统中最大反向电压、预计浪涌能量及工作环境温度，必要时选择更高规格或并联/串联方案以满足电流与耐压要求。若对正向压降或开关速度有更高要求，可考虑快速恢复或肖特基二极管替代，但需权衡耐压和漏电特性。
七、结语
DOWO（东沃）1N4007W 将传统通用整流器件的高耐压特性与现代 SMD 封装相结合，适合追求体积紧凑且需要千伏级反向耐压的应用场景。在保证散热与浪涌保护的前提下，可提供长期稳定的整流与保护功能，是高压低至中等电流电路的理想选择。若需详细的典型波形、封装尺寸和回流焊工艺，请参阅厂家数据手册。

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.
