SS36（KUU）肖特基二极管 产品概述
一、产品要点
SS36 是KUU品牌的独立式肖特基整流二极管，封装为SMB（DO-214AA）。主要电气参数如下：正向压降 Vf = 700 mV @ 3 A，额定整流电流 3 A，直流反向耐压 Vr = 60 V，非重复峰值浪涌电流 Ifsm = 100 A。工作结温范围为 -50 ℃ ~ +125 ℃。反向漏电流规格在 60 V 时为数百微安量级（资料中标注 300 μA@60 V，另有资料列出 500 μA@60 V，视测试条件与批次可能有差异）。
二、电性能与特点
- 肖特基结特性使其在导通时正向压降低、开关速度快，适合高频整流与开关电源回路。Vf=700 mV@3 A 在同电流级别的硅整流器中具有明显的导通损耗优势。
- 反向漏电流（Ir）相对较高，为肖特基器件的典型特性，且随温度升高呈指数上升，应在热设计中考虑。
- Ifsm=100 A 表示对瞬态浪涌（如开机浪涌或整流电容充电电流）有良好承受能力，但该值为单次或短时脉冲，应避免重复超过额定整流电流与热极限。
三、典型应用场景
- 开关电源（SMPS）输出二次整流或同步整流替代器件；
- DC-DC 转换器、降压/升压模块的自由轮回路；
- 反向极性保护、整流桥或单相整流器（中小功率）；
- 汽车电子、充电器、工业电源中需要低压降、高效率的整流场合。
四、封装与热管理
SMB（DO-214AA）封装便于手工焊接与自动贴装，具有一定的散热面积，但在3 A 持续工作条件下需关注结-外壳与PCB铜箔的散热：
- 推荐在PCB上为二极管阴极/阳极侧配备较大面积的散热铜箔，并通过多孔过孔与底层散热层连通；
- 在高环境温度或靠近热源的布局，应对整流电流进行额定功率的热降额设计，确保结温不超过 125 ℃。
五、选型与使用建议
- 若电路对正向压降极为敏感，可优先考虑 Vf 更低的同步整流或更高规格的肖特基；若对漏电流敏感（如低功耗待机电路），应评估 Ir 在工作温度下的影响。
- 浪涌和短路保护：在可能存在大电容充电或短路的场景，应配合限流器件（NTC、保险丝）或设计限流电路，避免频繁接近 Ifsm。
- 焊接工艺：按照SMB封装的推荐回流曲线进行，避免长时间高温导致器件热损或参数漂移。
六、总结
KUU 的 SS36 为一款面向中小功率整流与开关电源应用的肖特基二极管，结合 60 V 耐压、3 A 额定电流及较高的浪涌承受能力，适用于需要较低正向压降和快速恢复的电源电路。在设计时需权衡其反向漏电流随温度上升的特性，并做好PCB散热与浪涌保护措施，以保证长期可靠运行。

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.
