DOWO 通用独立式整流二极管（SOD-123FL）产品概述
一、产品简介
本产品为DOWO（东沃）品牌的通用独立式整流二极管，采用小型贴片封装 SOD-123FL，设计用于高电压整流和一般功率应用。器件工作结温范围宽 (-55 ℃ ～ +150 ℃)，在1A工作电流条件下正向压降仅为1.1V，兼具高耐压与低正向损耗的平衡特性，适合空间受限但要求高压耐受能力的电子系统。
二、主要电气参数
- 工作结温范围：-55 ℃ ～ +150 ℃
- 正向压降（Vf）：1.1V @ If = 1A
- 直流反向耐压（Vr）：1000V (1kV)
- 反向漏电流（Ir）：5 μA @ Vr = 1kV
- 整流电流（Io）：1A（连续）
- 非重复峰值浪涌电流（Ifsm）：30A（单次脉冲）
- 配置形式：独立式（单只二极管）
三、主要特性与优势
- 高耐压：1kV的反向耐压适用于离线电源、高压整流与峰值检波等场合。
- 低漏电流：在额定反向电压下漏电流仅数微安，利于高阻态电路与低功耗设计。
- 良好浪涌承受能力：30A的单次浪涌能力可以应对启动或瞬态冲击电流。
- 小型SMD封装：SOD-123FL封装便于贴片生产与高密度布局，同时提高散热效率与可靠性。
- 宽温工作范围：满足工业级应用在严苛环境下的可靠性要求。
四、典型应用场景
- 开关电源次级或整流回路的高压整流
- 离线电源、适配器与充电器中的高压整流器件
- 峰值检波、电压倍增器与直流高压产生电路
- 工业控制、电机驱动及继电器保护电路的反向保护与整流
- 仪器仪表及其它需要小体积高耐压整流的场合
五、封装与可靠性建议
SOD-123FL为低剖面表贴封装，建议在PCB上采用配套焊盘及散热铜箔，保证热阻和焊接可靠性。推荐使用标准回流焊工艺进行贴装，遵循厂商提供的回流曲线和温度限制，避免超温造成器件性能下降。若电路长期工作在大电流或高结温条件下，应增设散热铜层或散热器，提高器件寿命与稳定性。
六、选型与使用注意事项
- 在选型时确认最大反向电压留有适当裕度（建议Vr裕量≥20%），以应对电网波动或瞬态脉冲。
- 对于频繁开关或高频应用，若需要快速恢复特性，请核实器件恢复时间或选择专用快恢复/肖特基方案。
- 浪涌电流为非重复峰值（Ifsm），仅用于短时冲击评估，不应作为持续工作电流使用依据。
- 订购与验收时请明确品牌、封装与关键电气参数，例如：DOWO，独立式，SOD-123FL，Io=1A，Vr=1kV，Vf=1.1V@1A。

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.
