MBR20200CG 产品概述

一、产品简介

MBR20200CG 是富芯森美(FUXINSEMI)推出的一款高压肖特基整流二极管,采用 TO-263(D2PAK)大功率表面贴装封装。器件为一对共阴极配置(双二极管共阴),面向开关电源、整流模块、续流和反向保护等电力电子场合,兼顾高电压耐受与较低正向压降的需求。

二、主要电气参数

  • 型号:MBR20200CG
  • 配置:1对共阴极(双二极管共阴)
  • 正向压降(Vf):920 mV @ 10 A
  • 直流反向耐压(Vr):200 V
  • 直流整流电流:20 A
  • 非重复峰值浪涌电流(Ifsm):150 A
  • 结温工作范围:-55 ℃ ~ +175 ℃
  • 反向漏电流(典型):100 nA(具体测试条件见产品规格书)
  • 封装:TO-263(有利于散热与大电流承载)

三、器件特点与优势

  • 高反向耐压:200 V 的反向耐压能够满足较高电压轨的整流和防反接需求,适用于中高压电源设计。
  • 低正向压降:在 10 A 条件下约 0.92 V 的正向压降,可有效降低整流损耗与发热,相较于普通硅整流器在效率上更有优势。
  • 大电流承载:20 A 的整流电流和 150 A 的单次浪涌能力,适配高起动电流或瞬态负载场景。
  • 宽温工作范围:器件支持 -55 ℃ 到 +175 ℃ 的结温,适合工业和电力电子的苛刻环境。
  • TO-263 封装:低热阻、易于 PCB 散热设计,便于并联或与散热片结合使用以提升热性能。

四、典型应用场景

  • 开关电源整流(主回路与输出整流)
  • 逆变器与电机驱动器的自由轮回路
  • 充电器与适配器整流单元
  • 太阳能逆变/汇流箱、汽车电子非苛刻电源部分(注意热管理与温度对漏电流的影响)
  • 低压降反向保护及二极管桥替代方案

五、封装与热管理建议

TO-263 封装对热管理友好,但在长期高功率工作下仍需注意:

  • 在 PCB 设计中使用足够的铜箔面积和的散热通孔,优先将焊盘与散热层相连;
  • 必要时搭配散热片或底部导热胶,以保持结温在安全范围内;
  • 留意环境温度对整流电流的降额,随结温升高,允许的平均整流电流应按规格书曲线进行降额处理;
  • 反向漏电流随温度显著增加,热设计对系统整体效率和待机功耗影响明显。

六、选型与使用注意事项

  • 验证应用最大电压及瞬态尖峰是否超出 200 V,必要时在输入端加浪涌吸收或 RC/TVS 保护。
  • 关注 Vf 在工作电流下的表现,若系统对压降敏感,可在实际工作点上核算功耗与结温。
  • 若需并联使用以提升电流能力,应保证器件的热分布均匀并采用合适的电流均流措施(焊盘对称、相同走线阻抗等)。
  • 安装与回流焊接时遵循厂商给出的焊接曲线,避免超温导致封装或器件性能劣化。
  • 对于高可靠性或安全关键系统,请参考完整数据手册并做应力测试验证。

七、总结

MBR20200CG 以其 200 V 的耐压、约 0.92 V 的 10 A 正向压降、20 A 的整流能力和 TO-263 强散热特性,构成了在中高压开关电源与功率整流场合的实用选择。合理的热设计与电压保护配合能够充分发挥其寿命与性能,建议在最终方案中参照规格书的热特性与电气特性曲线进行工程验证与可靠性评估。若需更详细的电气特性曲线、封装尺寸或焊接建议,请参阅富芯森美提供的完整产品资料。

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
