MBR20200CD 产品概述

一、产品简介

MBR20200CD 是扬杰(YANGJIE)推出的一款肖特基整流二极管,采用一对共阴极(dual common-cathode)结构,封装为 TO-252(DPAK)。产品面向高效率电源、开关电源和功率整流场景,兼顾低正向压降和高电压阻断能力,适合需要大电流和低损耗的设计。

二、主要性能指标

  • 正向压降(Vf):900 mV @ 10 A
  • 直流反向耐压(Vr):200 V
  • 连续整流电流:20 A
  • 非重复峰值浪涌电流(Ifsm):130 A(一次性浪涌)
  • 反向漏电流(Ir):100 μA @ 200 V
  • 工作结温范围:-55 ℃ ~ +175 ℃
  • 封装:TO-252(DPAK)
  • 结构:一对共阴极肖特基二极管

三、产品特性与优势

  • 低正向压降:在大电流工况下 Vf 较低,可显著降低导通损耗,提高转换效率。
  • 高电压耐受:200 V 的反向耐压满足中高压整流与保护需求。
  • 高温稳定性:高达 +175 ℃ 的结温上限,利于苛刻环境和汽车级应用。
  • 良好浪涌能力:130 A 的非重复峰值浪涌能力,可应对启动或短时冲击电流。
  • 封装便于散热和表贴:TO-252 便于自动化贴装并配合铜箔散热。

四、典型应用场景

  • 开关电源(SMPS)次级整流或同步整流替代件
  • 太阳能逆变器、PV 系统的高压整流环节
  • 各类适配器、充电器的输出整流与反向保护
  • 车载电源与电源管理模块(注意温度与散热设计)
  • 电机驱动与功率变换器的续流与钳位电路

五、封装与安装建议

采用 TO-252(DPAK)表面贴装,建议在 PCB 上设置足够的散热铜箔和过孔以降低结-壳热阻。焊盘设计要保证焊点完整、热回流均匀;器件附近避免热源堆积。若工作在接近额定电流或高结温工况,应考虑外部散热器或加大 PCB 散热面积。

六、可靠性与使用注意事项

  • 反向漏电流随温度上升显著增加,需在高温工况下验证漏电对系统的影响。
  • Ifsm 为非重复峰值,禁止重复或长期超限冲击。
  • 建议在最终应用中进行热仿真和实测验证,确定结温低于最高额定值以保证长期可靠性。
  • 对于敏感电路,考虑并联或加缓冲电路以平衡电流分布和抑制电压尖峰。

MBR20200CD 以其低 Vf、高耐压与宽温度范围,适合对效率和可靠性有较高要求的功率整流场合。设计时重点关注散热与高温漏电特性,以发挥该器件的最佳性能。

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
