SS320F 产品概述
一、概述
SS320F 为晶导微电子出品的肖特基整流二极管，单体峰值整流电流3A，直流反向耐压达200V，采用SMAF小型封装。肖特基结构赋予其低正向压降、快速恢复特性，适合中功率、高效率电源及保护电路应用。
二、主要特点
- 正向压降：Vf = 950mV @ 3A（典型），降低导通损耗。
- 反向耐压：Vr = 200V，满足中高压整流要求。
- 反向电流：Ir = 300µA @ 200V，漏电小，有利于高阻抗回路与待机功耗控制。
- 最大整流电流：IF = 3A（直流）；非重复峰值浪涌电流Ifsm = 80A，具备较强浪涌承受能力。
- 工作结温范围：-55℃ ～ +125℃，适应宽温度环境。
- 封装：SMAF，体积小，便于自动贴装和密集布局。
三、电气与热性能要点
- 导通损耗估算：P ≈ Vf × IF（例如3A时约2.85W），需结合PCB散热设计控制结温。
- 建议在大电流应用中增加焊盘铜厚或散热铜箔，若靠近高热源应留出散热通道。
- 避免在超过额定Ifsm的条件下反复冲击，以免影响寿命。
四、典型应用
- 开关电源及快恢复整流
- DC-DC转换器输出整流
- 反向极性保护、电池充放电管理
- 太阳能逆变器、工业电源、车载电子（需评估工作电压及温度）
五、封装与可靠性
SMAF 封装兼顾热性能与占板面积，适合SMT生产。产品经过常规电气和温度循环验证，推荐在元件周围保留合理散热铜地和热焊盘以提升长期可靠性。
六、使用与存储注意事项
- 推荐在合适的回流焊曲线下焊接，避免长时间超温；存储时防潮、防静电。
- 在设计时预留安全裕量（电流、电压及浪涌能力），并考虑实际工作温升对Vf和Ir的影响。

Request for quote
Send RFQ
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.
