1N4007WS 产品概述
一、产品简介
1N4007WS 是杰盛微（JSMSEMI）推出的一款小功率通用整流二极管，采用 SOD-323 表面贴装封装，适合对体积和成本有严格要求的消费类与工业类电子设备。器件在低电流条件下具有较低的正向压降和较小的反向漏电流，适用于小电流整流、反向保护和信号限幅等场景。
二、主要电气参数
- 正向压降 (Vf)：1.0 V @ If = 50 mA
- 直流反向耐压 (Vr)：300 V
- 最大整流电流：300 mA（连续）
- 反向电流 (Ir)：1 μA @ Vr = 75 V
- 非重复峰值浪涌电流 (Ifsm)：2 A（短时浪涌）
- 封装：SOD-323（表面贴装）
- 品牌：JSMSEMI（杰盛微）
三、产品特点
- 高耐压：300 V 的反向耐压适合中高压小电流整流需求。
- 低漏电流：在 75 V 时反向电流仅 1 μA，有利于降低静态损耗和提高待机功耗表现。
- 小尺寸封装：SOD-323 小巧，适合高密度 PCB 布局与节省空间的便携设备。
- 良好浪涌能力：2 A 的非重复峰值浪涌允许器件承受短时启动或突发脉冲电流。
四、典型应用场景
- 低功率开关电源与电源管理电路的小电流整流。
- 便携式设备（充电器、移动电源）中作反向保护或极性保护。
- 工业与家电中做信号钳位、过压保护的辅助元件。
- 电子测试与仪器中用于低电流直流通路的整流或隔离。
五、封装与可靠性
SOD-323 为常用的小型贴片封装，适配主流贴片生产线与回流焊工艺。由于封装体积小，器件对散热较为敏感，在接近额定整流电流工作时应注意布局与热管理，避免长期高温环境下的电性能退化。推荐在 PCB 布局时为二极管附近留有适度铜箔散热通道。
六、使用建议与注意事项
- 工作电流应在额定整流电流（300 mA）以内，连续高电流会引起正向压降和温度上升。
- 浪涌电流能力为短时 2 A，长期或重复浪涌需额外评估可靠性。
- 在 50 mA 条件下正向压降约 1 V，设计时需考虑功耗与热量。
- 对静电敏感，贴片和存储时遵循常规静电防护措施。
- 回流焊工艺下应按元件供应商推荐的温度曲线进行焊接，避免过高峰值温度和长时间暴露。
七、订购信息与替代件
型号：1N4007WS
品牌：JSMSEMI（杰盛微）
封装：SOD-323
应用设计中若需更大电流或不同耐压等级，可考虑同系列或其他型号替代，替换时请重点核对最大整流电流、反向耐压、正向压降与浪涌能力等关键参数，确保满足电路要求。
如需样品、器件性能曲线或封装尺寸图，请联系供应商或查阅杰盛微官方数据手册以获取详细规范与测试条件。

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.
