MBR230LSFT1G 产品概述

一、产品简介

MBR230LSFT1G 是富芯森美(FUXINSEMI)推出的一款独立式肖特基整流二极管,采用 SOD‑123 小封装,面向空间受限但对效率有较高要求的电源与保护类应用。该器件以低正向压降和快速恢复特性著称,典型正向压降为 430 mV(IF = 2 A),最高直流反向耐压为 30 V,额定整流电流为 2 A,能在中等电流密度下提供优秀的导通效率与热性能。

二、主要特性

  • 低正向压降:Vf = 430 mV @ IF = 2 A,有利于降低导通损耗、提升系统效率。
  • 低反向漏电:Ir = 200 μA @ VR = 30 V,适合对待机功耗和漏电敏感的应用。
  • 额定整流电流:2 A(连续),适用于中等功率整流与保护电路。
  • 高浪涌能力:非重复峰值浪涌电流 Ifsm = 40 A(峰值),满足短时浪涌和启动冲击要求。
  • 宽温度范围:结温工作范围 -55 ℃ ~ +125 ℃,适应工业级温度环境。
  • 小封装:SOD‑123,节省 PCB 面积,便于自动化贴装与批量生产。

三、电气参数(典型/关键)

  • 正向压降(Vf):0.43 V @ IF = 2 A(典型值)
  • 直流反向耐压(Vr):30 V(最大)
  • 连续整流电流:2 A
  • 反向电流(Ir):200 μA @ VR = 30 V
  • 非重复峰值浪涌电流(Ifsm):40 A
  • 工作结温:-55 ℃ ~ +125 ℃
    注:器件参数以富芯森美规格书为准,设计时请留有裕量并参考典型温度依赖曲线。

四、典型应用场景

  • 开关电源(SMPS)中的整流与续流二极管
  • DC‑DC 降压/升压转换器的输出整流与回灌保护
  • 车载电源与电子控制单元(ECU)中的反接与浪涌保护(在 30 V 以内)
  • 电池充电管理与选择性电源切换
  • LED 驱动与电源路径保护
  • 一般电子设备中的极性保护与反并联整流

五、封装与热设计建议

SOD‑123 为小型表贴封装,有利于节省空间但相对热阻较高。实际 PCB 设计和散热处理会显著影响器件的允许连续电流和热稳定性,建议:

  • 在二极管焊盘周围采用较大铜箔面积或接地/电源平面,提高散热能力;
  • 增加散热孔(vias)连接到内层或底层铜平面,以改善板内热传导;
  • 缩短二极管到热沉或大铜块的走线,避免细长走线造成热集中;
  • 在高功率或高环境温度场景下进行热仿真或实测,必要时选择更大封装或并联多颗器件以分摊热量。

六、选型与使用建议

  • 若系统电流接近或超过 2 A,需考虑器件温升、环境温度及 PCB 散热能力,建议留足余量或采用并联方案;
  • 对于更高反向耐压需求,应选择更高 Vr 等级的肖特基或肖特基与普通整流器配合使用;
  • 在开关频率较高的应用中,肖特基二极管的低反向恢复特性可降低开关损耗,但仍需关注寄生电感与布局导致的 EMI;
  • 垂直或水平安装时注意极性标识(通常阴极有标记),焊接过程遵守厂商推荐的回流曲线以避免过热损伤。

七、可靠性与存储

  • 器件符合常规半导体储存与运输要求,建议在干燥环境下保存,避免长期潮湿引起焊接缺陷;
  • 推荐在允许的焊接温度曲线下进行回流焊,若采用手工焊接需控制热时间与温度;
  • 对于汽车或工业级应用,建议参考富芯森美的可靠性数据与寿命测试报告以满足系统级认证要求。

总结:MBR230LSFT1G 以其低正向压降、较低漏电和 SOD‑123 小封装的组合,适合对效率和封装尺寸有严格要求的中等功率整流与保护场景。合理的 PCB 热设计和选型裕量能确保器件在长期工作中的稳定性与可靠性。若需完整规格书或器件采购信息,请联系富芯森美或授权分销商获取最新资料。

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.
