FR107W 快恢复二极管产品概述

一、核心参数总览

FR107W是FOSAN(富信)推出的快恢复/高效率二极管,核心参数围绕「高压耐量、快恢复特性、低导通损耗」设计,精准匹配中高压小功率电源场景:

  • 正向压降(Vf):1.3V(典型值,测试条件:1A正向电流);
  • 直流反向耐压(Vr):1000V(峰值,可承受AC220V整流后的反向高压);
  • 平均整流电流(If(AV)):1A(直流工况下持续导通电流,满足多数小功率负载);
  • 反向恢复时间(Trr):500ns(快恢复特性,远短于普通整流管的μs级);
  • 工作结温范围:-65℃~+150℃(工业级宽温,覆盖极端环境);
  • 封装形式:SOD-123FL(表面贴装,小型化高密度布局适配)。

二、关键性能特性

  1. 快恢复提升高频效率
    500ns的反向恢复时间,可大幅减少开关过程中的反向恢复损耗——普通整流管在高频(如几十kHz)下会因恢复慢产生额外发热,而FR107W能适配开关电源(SMPS)、逆变器等高频电路,避免效率下降。

  2. 低VF降低导通损耗
    1A电流下仅1.3V的正向压降,相比同参数竞品(部分FR107的Vf达1.5V以上),导通损耗可降低约15%。这一特性对LED驱动、便携充电器等「效率敏感」场景尤为重要,能减少散热片需求,简化电路设计。

  3. 高压耐量覆盖宽场景
    1000V的反向耐压,可直接应用于AC110V/220V输入的电源电路(整流后反向电压峰值约310V/620V,远低于1000V安全裕量),避免反向击穿风险。

  4. 宽结温保障可靠性
    -65℃~+150℃的工作结温,覆盖了工业控制(如车间高温环境)、汽车电子(发动机舱120℃以上)、户外设备(低温严寒)等严苛场景,长期工作失效率低。

三、封装与可靠性设计

FR107W采用SOD-123FL表面贴装封装,兼具「小型化」与「可靠性」:

  • 体积小巧:封装尺寸仅2.5mm×1.2mm×1.0mm,适合智能手机充电器、便携式医疗设备等轻薄化产品的高密度布局;
  • 贴装便捷:符合SMT自动生产工艺,可通过贴片机高效组装,降低人工成本;
  • 耐候性强:封装采用耐高温环氧树脂,能承受多次温度循环(-40℃~125℃循环1000次)和机械应力,长期工作稳定。

四、典型应用场景

FR107W的参数特性使其成为以下场景的优选器件:

  1. 开关电源(SMPS):作为续流二极管或整流管,用于AC-DC转换电路(如手机充电器、笔记本电源适配器),适配30~200kHz开关频率;
  2. LED驱动电源:为小功率LED模组(台灯、显示屏背光)提供整流,1A电流容量满足多数模组需求,低VF减少电源损耗;
  3. 逆变器与转换器:在DC-AC逆变器(如太阳能微型逆变器)的续流回路中,承受高频反向电压,快恢复特性避免反向恢复电流过大;
  4. 工业控制电路:用于传感器供电、继电器驱动等辅助电路,宽温特性适配车间温度波动(-20℃~85℃);
  5. 汽车电子:车载充电器、仪表盘背光电源等,1000V耐压和宽温满足汽车环境的严苛要求。

五、选型与替换建议

  • 同品牌替换:若需更高电流(如2A),可选FOSAN FR207W(2A、1000V、500ns);若需更低电压(600V),可选FR106W;
  • 跨品牌替换:需匹配「Vr≥1000V、If(AV)=1A、Trr≤500ns、封装SOD-123FL」,如某品牌FR107W-TP可直接替换;
  • 注意事项:应用时需确保反向电压不超过1000V峰值,平均电流不超过1A,结温不超过150℃,避免过压过流损坏。

FR107W凭借「快恢复、低损耗、高压宽温」的综合优势,成为小功率高压电源电路的核心器件,覆盖消费电子、工业控制、汽车电子等多领域,其小型化封装也契合了现代电子设备的轻薄化趋势。

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.
