M7 通用整流二极管（YONGYUTAI，SMA封装）产品概述
一、产品简介
M7 为 YONGYUTAI（永裕泰）品牌的通用整流二极管，采用 SMA 表面贴装封装，额定整流电流 1A，直流反向耐压达 1kV。器件为独立式二极管，适用于各种中等电压整流与保护场合，器件工作结温范围宽 (-55℃ 至 +150℃)，可靠性高，适应工业级温度环境。
二、主要性能参数
- 正向直流电流（IF）：1A（连续整流电流）
- 正向压降（Vf）：1.1V @ IF=1A
- 直流反向耐压（VR）：1000V（1kV）
- 反向漏电流（IR）：5µA @ VR=1kV
- 非重复峰值浪涌电流（Ifsm）：30A（单次浪涌）
- 工作结温范围：-55℃ ~ +150℃
- 封装：SMA（表面贴装）
三、核心特点与优势
- 高耐压：1kV 的反向耐压适用于中高压整流与保护场景。
- 低漏电：在满压条件下漏电流仅 5µA，有利于高阻抗或漏电敏感电路。
- 良好浪涌能力：30A 的单次浪涌电流可应对短时间启动或容性负载冲击。
- 宽温度范围：工业级工作温度，适合恶劣环境应用。
- 标准封装：SMA 封装便于自动化贴装与常规回流焊工艺。
四、典型应用场景
- 开关电源的整流与续流回路
- 电机驱动、继电器及接触器的浪涌保护
- 充电器、适配器及家电内部整流
- 测试设备与工业控制系统中高压整流或阻止反向电流场合
五、封装与热性能
SMA 封装具备较小的占板面积和良好的焊接兼容性。尽管连续电流额定为 1A，实际使用时应考虑 PCB 散热设计与焊盘铜层厚度，必要时采用加宽铜箔或热铜垫以降低结温。器件在高结温下应进行电流降额以保证长期可靠性。
六、选型与使用建议
- 若电路频繁承受反复高浪涌或需要更低正向压降，建议选择更高 Ifsm 或低 Vf 的肖特基或快恢复二极管。
- 在高环境温度或密集布板场合，考虑增加散热措施并按温度特性曲线降额使用。
- 验证反向漏电对系统影响，若要求更低漏电可选额外等级产品。
七、注意事项与可靠性
- 推荐遵循厂商推荐的回流焊温度曲线，避免超温引发封装应力。
- 存储与装配过程中注意防潮、防静电处理。
- 对焊接后可能的热循环与机械应力进行可靠性验证，关键应用建议做寿命与热冲击测试。
总结：M7（YONGYUTAI，SMA）为一种通用、耐压高、漏电低的 1A/1kV 整流二极管，适合工业及民用中高压整流与保护场合，选型时注意热管理与浪涌能力匹配。

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.
