SK16D3 产品概述

一、产品简介

SK16D3 是 FUXINSEMI(富芯森美)出品的一款独立式肖特基整流二极管,封装为 SOD-323。其额定直流整流电流为 1A,反向耐压(Vr)为 60V,在 1A 工作电流下正向压降(Vf)典型值为 700mV。该器件适用于小体积电源整流、反向保护、开关电源快速恢复和功率路径选择等场景,兼顾低正向压降与小体积封装的需求。

二、主要电气参数

  • 二极管配置:1 个独立二极管
  • 正向压降 Vf:700 mV @ 1 A
  • 直流反向耐压 Vr:60 V
  • 额定整流电流(If):1 A(连续)
  • 反向漏电流 Ir:100 μA @ 60 V
  • 非重复峰值浪涌电流 Ifsm:10 A(一次性冲击规格)
  • 封装:SOD-323(小型贴片封装)

三、产品特点与优势

  • 低正向压降:在 1A 工作点上约 0.7V,有利于降低整流损耗、提高效率。
  • 小型封装:SOD-323 体积小,利于空间受限的移动设备、便携电源与消费电子的电路板布局。
  • 合理的耐压与电流能力:60V 反向耐压与 1A 的连续整流能力,覆盖常见的中低压应用。
  • 良好的浪涌承受能力:10A 的非重复峰值浪涌抵抗短时冲击,适合瞬态启动或浪涌环境。

四、典型应用场景

  • 开关电源(SMPS)输出整流与同步整流辅助通道;
  • 车载电子与工业控制中的反向极性保护(注意温度对漏电流的影响);
  • USB、电池供电设备中的低压整流与电源路径切换;
  • 小功率电源模块、充电器与适配器的二极管整流阵列。

五、使用注意事项与热设计

  • 功耗评估:在 1A 连续工作时,P ≈ Vf × If ≈ 0.7W,SOD-323 小封装对散热有限,实际结温需结合 PCB 铜箔面积和环境温度进行热设计与降温。
  • 漏电流注意:反向漏电流在 60V 时为 100 μA,温度升高会显著增加漏电流,需在高温或高灵敏度电路中评估影响。
  • 浪涌与降额:虽然 Ifsm 可达 10A(非重复峰值),但不可作为长期承载,应避免反复大电流冲击,必要时选用更大封装或并联方案并做好热保护。
  • 焊接工艺:遵循制造商推荐的回流焊温度曲线和时间,避免过热导致封装应力或性能退化;存放及贴装时注意防潮处理与静电防护。

六、封装与引脚说明

  • 封装:SOD-323 小型贴片封装,适合高密度组装。
  • 极性识别:器件一侧通常有阴极标记(如色带或凹槽),实际标识以产品出厂标志为准,贴装前应确认极性方向避免反接。

七、选型建议与限制

  • 选择 SK16D3 的理由:需要在 60V 以内、连续电流约 1A、空间受限并且希望尽量降低整流压降的场合。
  • 不适合的场景:长期大于 1A 的应用、需要极低反向泄漏(如高精度采样或高温下漏电敏感电路)或需要更高耐压/更强散热的中高功率场合,应考虑更大封装或更低漏电的肖特基产品。

八、质量与采购信息

  • 品牌:FUXINSEMI(富芯森美)
  • 包装与批量:请参阅厂家数据手册或与供应商确认最小起订量、卷装规格与包装防潮等级。
  • 资料与测试:选购与设计前建议取得 SK16D3 的完整数据手册核对回流焊曲线、热阻、典型特性曲线及可靠性试验报告。

如需更详细的参数曲线、典型应用电路或 PCB 布局建议,可提供设计环境与工作条件,我会给出更针对性的设计与热管理方案。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
