MBR10100CT 肖特基整流二极管产品概述

MBR10100CT是MDD品牌推出的共阴极双管肖特基整流二极管,采用TO-220AB-3封装,专为中等功率、高频或低压整流/续流场景设计,兼具低正向压降、快速开关特性与良好散热能力,是开关电源、DC-DC转换器等领域的常用器件。

一、产品基本定位与结构

该器件属于肖特基势垒二极管(SBD) 范畴,核心是金属-半导体接触形成的势垒,无PN结少数载流子存储效应,因此开关速度远高于传统硅管。

产品采用1对共阴极配置:内部集成两个独立肖特基二极管,阳极分别引出引脚,阴极共接为公共引脚,这种结构可简化整流桥、续流电路的PCB布局,减少器件数量。封装为TO-220AB-3(3引脚功率封装),带安装孔,可直接固定在散热片上,满足功率应用的散热需求。

二、核心电气参数详解

MBR10100CT的参数针对中等功率低压应用优化,关键指标如下:

1. 正向特性

  • 正向压降(Vf):850mV@10A(额定连续正向电流下的典型值),比同电流等级硅整流管(如10A硅管Vf≥1.1V)低约23%,导通损耗显著降低,提升电源效率;
  • 正向电流:额定连续正向电流(IF(AV))10A(25℃环境温度),峰值正向电流(IFSM)参考规格书(通常100A/10ms脉冲)。

2. 反向特性

  • 直流反向耐压(Vr):100V(反向峰值电压VRRM对应100V),属于低压肖特基范畴,适配12V/24V系统等低压场景;
  • 反向漏电流(Ir):1mA@100V(反向偏置100V时典型值),漏电流处于合理范围,高温下(如125℃)略有增加但仍在允许值内。

3. 开关特性

肖特基二极管的反向恢复时间(trr) 为ns级(通常<50ns),远快于普通硅管的μs级(如1N4007 trr≈30μs),适合几十kHz到几百kHz的高频开关电源应用,减少开关损耗。

三、封装与物理特性

MBR10100CT采用TO-220AB封装,是成熟的功率器件封装形式,特点如下:

  • 引脚配置:3引脚设计,共阴极结构下,引脚1/3为阳极(A1/A2),引脚2为公共阴极(K);
  • 散热设计:底部带金属散热片,通过安装孔固定散热片+导热硅脂,可有效降低结温;
  • 尺寸规格:标准TO-220AB尺寸(长≈10mm,宽≈7mm,高≈5mm),引脚间距符合工业标准,便于PCB焊接与替换。

四、典型应用场景

结合参数与特性,该器件主要适用于:

  1. 开关电源(SMPS):低压输出端整流(如12V/5V电源次级),低Vf降低损耗;
  2. DC-DC转换器:Buck电路续流二极管,快速恢复特性减少开关损耗;
  3. 车载电子:12V/24V系统整流/续流(如车载充电器、LED驱动);
  4. 电池充电电路:充电保护或整流二极管,低损耗减少能量浪费;
  5. 小型逆变器:输出端整流,适配100V以下低压场景。

五、产品优势与注意事项

1. 核心优势

  • 低损耗:850mV@10A的正向压降,显著降低导通损耗;
  • 高频适配:ns级反向恢复时间,适合高频开关应用;
  • 布局简化:共阴极双管结构,减少器件数量与PCB面积;
  • 散热可靠:TO-220AB封装便于散热,满足功率需求。

2. 注意事项

  • 耐压余量:反向耐压100V,实际反向峰值电压需控制在80V以内(留20%余量);
  • 温度降额:25℃下10A,75℃时需降额至约7A(参考降额曲线);
  • 散热要求:近10A电流时需搭配TO-220专用散热片+导热硅脂;
  • 漏电流控制:避免长期处于100℃以上环境,防止漏电流累积功耗。

综上,MBR10100CT是一款性能均衡的中等功率肖特基二极管,在低压、高频整流/续流场景中优势明显,适合工业电源、车载电子等领域批量应用。

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.
