MBRF20100CT 肖特基二极管产品概述

MBRF20100CT是MDD品牌推出的共阴极肖特基整流二极管,采用ITO-220AB-3封装,专为中等功率低压电源系统设计,兼具低导通损耗、宽温适应性与强浪涌耐受能力,可满足工业、车载及通信设备等场景的整流/续流需求。

一、产品核心配置与封装

MBRF20100CT采用1对共阴极二极管结构,即两个肖特基二极管的阴极共接,阳极分别引出独立引脚——这种集成化设计可简化双二极管应用场景的电路布局(如全波整流、双向续流),无需额外并联两个独立器件,节省PCB空间。

封装为ITO-220AB-3(通孔式TO-220AB变体),具备良好的散热性能:引脚间距合理,便于焊接与散热器安装,可通过加装铝制散热器进一步提升功率承载能力,适合功率密度要求适中的电源模块。

二、关键电气性能解析

MBRF20100CT的参数针对性优化了低压功率场景,核心性能如下:

  • 正向特性:正向压降(Vf)仅850mV@10A,在20A额定整流电流下,导通损耗计算为20A×0.85V=17W,处于同类产品合理区间,可通过常规散热器有效散热;
  • 反向特性:直流反向耐压(Vr)100V,满足12V/24V等低压电源的反向阻断需求;反向漏电流(Ir)1mA@100V,远低于常规肖特基二极管的漏电流水平,能减少系统待机损耗,提升效率;
  • 浪涌与结温:非重复峰值浪涌电流(Ifsm)150A,可应对开机瞬态浪涌(如电容充电电流);工作结温范围-55℃~+150℃,覆盖工业级宽温要求,适应极端环境(如汽车发动机舱高温、北方低温启动);
  • 电流承载:额定整流电流20A,适合100W~200W功率等级的电源系统(如车载充电器、小型工业电源)。

三、典型应用场景

基于参数特性,MBRF20100CT可广泛应用于以下场景:

  1. 开关电源:作为AC-DC转换器的全波整流二极管,或DC-DC降压模块的续流二极管,共阴极结构简化电路设计,提升电源效率;
  2. 车载电子:适配汽车发动机舱高温(可达120℃以上)及低温启动(-40℃以下),用于车载充电器、LED车灯驱动、车载信息系统辅助电源;
  3. 工业设备:应用于PLC、变频器、伺服驱动器的辅助电源,耐受工业环境的温度波动与瞬态干扰;
  4. LED驱动电源:作为续流二极管,低正向压降减少驱动电路热耗,延长LED使用寿命。

四、应用注意事项

为确保产品稳定运行,需注意以下要点:

  • 散热设计:当工作电流接近20A时,需根据环境温度计算散热器面积(如环境25℃时,需散热器热阻≤7.5℃/W),避免结温超过150℃上限;
  • 电压防护:反向电压不得超过100V,若系统存在过压风险(如雷击、电网波动),需并联TVS管或压敏电阻防护;
  • 浪涌控制:150A浪涌电流为单次非重复值,若系统存在频繁浪涌(如频繁开关),需额外增加浪涌抑制器件;
  • 焊接工艺:ITO-220AB封装的焊接温度需控制在260℃以下(持续时间≤10s),避免高温损伤芯片内部结构。

五、产品优势总结

MBRF20100CT的核心优势体现在:

  • 性能平衡:低导通损耗与宽温范围兼顾效率与环境适应性,适合复杂工况;
  • 集成化优势:共阴极结构节省PCB空间,降低电路设计复杂度;
  • 可靠性:MDD品牌工艺保障,反向漏电流小,浪涌耐受能力强,长期运行稳定性高;
  • 成本效益:中等功率段的性价比优势,适合批量工业与车载应用。

该产品可作为低压功率电源系统的优选肖特基二极管,满足多样化的整流/续流需求。

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.
