SR5100肖特基整流二极管产品概述

一、产品核心定位与命名规则

SR5100是一款独立式肖特基整流二极管,属于5A/100V等级的通用功率器件,核心用于低压大电流场景的整流及续流。其命名遵循行业惯例:

  • “S”代表肖特基(Schottky Barrier Diode),明确器件类型;
  • “R”代表整流功能(Rectifier),标注核心应用;
  • “5”对应额定整流电流5A,“100”对应直流反向耐压100V,清晰传递关键性能参数。

二、关键电气参数详解

SR5100的参数针对低压大电流应用优化,核心特性可支撑多场景稳定工作:

  1. 正向压降(Vf):850mV@5A,远低于普通硅整流管(同电流下通常≥1V)。低压降直接降低导通损耗,例如在12V输出电源中,每支器件可减少约15%的导通损耗,提升电源转换效率1~2个百分点;
  2. 直流反向耐压(Vr):100V,满足12V、24V等低压系统的反向耐压需求,避免器件因反向过压损坏;
  3. 反向漏电流(Ir):500μA@100V,处于肖特基二极管的典型漏电流范围,额定条件下长期工作无明显漂移,可靠性稳定;
  4. 非重复峰值浪涌电流(Ifsm):120A(8.3ms半波),可承受开机、负载突变等瞬间大电流冲击,适配电网波动较大的场景(如工业设备、车载系统);
  5. 工作结温范围:-55℃~+150℃,宽温特性支持极端环境应用(如户外设备、低温地区设备)。

三、封装与物理特性

SR5100采用DO-201AD轴向封装(用户此前提及的DO-27为笔误,以DO-201AD为准),封装优势显著:

  • 轴向引出脚设计,适配传统插件式PCB布局,安装便捷,无需特殊焊接工艺;
  • 塑料封装体积适中(直径约5mm,长度约10mm),散热性能优于小型封装,可满足5A连续工作的散热需求;
  • 封装材料具备防潮、抗振动能力,适合批量生产及长期使用,避免环境因素导致的性能衰减。

四、典型应用场景

结合参数特性,SR5100广泛覆盖以下场景:

  1. 开关电源适配器:如手机、笔记本电脑充电器,低压降提升充电效率,减少适配器发热,延长产品寿命;
  2. LED驱动电源:大电流LED阵列的整流环节,降低功耗避免LED因过热衰减,提升照明系统可靠性;
  3. 车载电子:宽温范围适配车载环境(-40℃~85℃),120A浪涌能力应对汽车启动时的瞬间电流冲击;
  4. 工业控制电源:100V耐压满足24V系统需求,浪涌能力适配工业电网波动,保障设备稳定运行;
  5. 小型逆变器:低压直流转交流时的整流/续流环节,低压降提升转换效率,适合家用光伏逆变器等场景。

五、可靠性与环境适应性

SR5100通过多项行业标准测试,确保长期稳定:

  • 温度循环测试(-55℃~150℃,1000次循环):验证宽温下的性能一致性,无参数漂移;
  • 湿热测试(85℃/85%RH,1000小时):评估封装防潮能力,避免水汽侵入导致短路;
  • 浪涌测试(符合IEC 61000-4-5标准):确认120A浪涌的承受能力,适配电网波动场景;
  • 环保认证:符合RoHS标准,无铅封装,适配绿色制造需求。

六、品牌与品质保障

SR5100由国内专业功率半导体厂商FUXINSEMI(富芯森美) 生产,该品牌专注肖特基、MOSFET等功率器件研发,产品具备:

  • 一致性好:批量生产时参数离散度≤5%,满足工业级应用对一致性的要求;
  • 供货稳定:具备年产千万级的生产能力,可支撑客户批量订单;
  • 售后保障:提供规格书、应用指导及不良品退换服务,降低客户选型风险。

综上,SR5100以“低压降、大电流、宽温适配”为核心优势,是低压大电流场景的高性价比肖特基整流二极管选择。

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
