S1PB-M3/84A 产品概述
一、产品简介
S1PB-M3/84A 是 VISHAY（威世）提供的一款通用整流二极管，适用于中低功率整流与保护场合。器件采用 DO-220AA (SMP) 封装，结构可靠，热性能优良，适合在工业级温度范围内长期工作。凭借低正向压降和极低的反向漏电流，本型号在开关电源、适配器、整流桥及反向保护等应用中具有很高的性价比。
二、主要特点
- 工作结温范围：-55 ℃ 至 +150 ℃，满足宽温度环境需求。
- 正向压降 Vf = 1.1 V @ If = 1 A，降低功耗与发热。
- 最高直流反向耐压 VR = 100 V，适合常见工商业电压等级。
- 反向电流 IR = 1 µA @ VR = 100 V，漏电小，静态损耗低。
- 非重复峰值浪涌电流 Ifsm = 30 A，具备良好的抗浪涌能力。
- 额定整流电流 1 A，满足多数中小功率整流要求。
- 封装：DO-220AA (SMP)，便于安装与散热处理。
三、典型电气参数（关键值）
- 正向压降（Vf）：1.1 V（1 A）
- 反向耐压（Vr）：100 V
- 反向电流（Ir）：1 µA（100 V）
- 整流电流：1 A
- 非重复峰值浪涌电流（Ifsm）：30 A
- 结温工作范围：-55 ℃ ~ +150 ℃
四、封装与热管理建议
DO-220AA (SMP) 封装利于热量传导到 PCB 或散热器。尽管器件在额定电流下工作稳定，但在连续高功率应用中仍建议采取以下措施以保证长期可靠性：
- 增大 PCB 铜箔面积或在焊盘下方添加散热层；
- 在需要时配合金属散热片或热垫使用；
- 设计时考虑热阻和结—环境温升，必要时对整流电流进行热降额。
五、典型应用场景
- 开关电源与线性电源的整流与续流；
- 充电器与适配器中的输出整流；
- 反向极性保护与防反接电路；
- 工控设备、家电、照明驱动等需要可靠整流的场合。
六、使用注意事项
- 避免长期在接近或超过额定结温的环境中工作；
- 谨防超出 Ifsm 的冲击浪涌以及超过 Vr 的反向电压，设计应包含浪涌保护与适当的冗余；
- 焊接时遵循 VISHAY 推荐的焊接工艺与温度曲线，避免过热造成器件性能退化；
- 在关键应用中建议对样品进行实际工作条件下的验证测试。
总结：S1PB-M3/84A 以其低正向压降、低漏电流、较高浪涌能力和宽工作温度范围，适合作为通用整流与保护二极管选型的优质选择。若需更完整的电气特性曲线、热阻参数或可靠性测试数据，请参阅 VISHAY 官方数据手册或联系供应商获取技术支持。

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.
