MBR3H60MB_R1_00001 产品概述

本产品为 PANJIT(强茂)出品的 MBR3H60MB_R1_00001,是一只独立式 Schottky 整流二极管,采用 SMB 封装。该器件针对中小功率开关电源及直流功率管理场景设计,具有低正向压降、高浪涌承受能力与宽工作结温范围,适合对效率与可靠性有较高要求的应用。

一、主要电气参数与物理特性

  • 二极管配置:单只独立式(单个二极管)
  • 正向压降:Vf = 700 mV @ IF = 3 A
  • 直流反向耐压:VR = 60 V
  • 额定整流电流:IF(AV) = 3 A
  • 反向漏电流:IR = 5 μA @ VR = 60 V
  • 非重复峰值浪涌电流:IFSM = 100 A
  • 工作结温范围:TJ = -55 ℃ ~ +175 ℃
  • 封装:SMB(表面贴装/带端子小型封装)
  • 品牌:PANJIT(强茂)

二、关键性能亮点

  • 低正向压降:在3 A 工作电流下 Vf ≈ 0.7 V,可显著降低整流损耗与发热,有利于提升开关电源与 DC-DC 转换器的效率。
  • 低反向漏电流:反向漏电仅为数微安,适合对待机功耗或反向泄漏敏感的系统。
  • 高浪涌承受能力:100 A 的非重复峰值浪涌电流使其对启动电流、充电脉冲与瞬态冲击有较好抗扰能力。
  • 宽温度范围与高结温上限:-55 ℃ 至 +175 ℃ 的结温范围适用于工业级、汽车电子(需结合系统验证)等苛刻环境。

三、典型应用场景

  • 开关电源(SMPS)输出整流与复位整流
  • DC-DC 转换器输出整流与同步替代
  • 逆接保护与低压差整流(如电池管理、备用电源)
  • 功率模块的自由轮回二极管(flyback/freewheeling)
  • 工业控制电源、电动车辆辅助电源(需满足系统级热与浪涌要求)

四、热设计与电气布局建议

  • 功率估算:在连续 3 A 工况下,器件耗散约 P = Vf × IF ≈ 0.7 V × 3 A = 2.1 W。请据此评估 PCB 铜箔面积与散热需求。
  • PCB 布局:在二极管焊盘下方或附近预留足够的铜箔,必要时增加热通孔(thermal via)导向内部或背铜层以提高散热能力。
  • 并联注意:若需更高电流能力,建议使用相同型号、相同布局的并联方案,并在电气上保证电流均分(焊盘阻抗一致),同时注意浪涌电流能力的叠加。
  • 焊接与可靠性:遵循 SMB 封装的回流焊工艺规范,避免超出封装耐温限制;长期高温会增加反向泄漏,应在系统热设计中留余量。

五、选型与替代建议

MBR3H60MB_R1_00001 适用于 60 V 等级、3 A 级别的常见整流场合。选型时应关注:

  • 实际工作电流峰值与连续电流大小,是否需要更低 Vf 或更高电流等级;
  • 工作环境温度与散热条件,评估 TJ 上升对 IR 增大的影响;
  • 是否需要更高的耐压(若系统有高压跨接应选择更高 VR 的型号)或更低的漏电流(例如高精度采样电路)。

如需更高电流或更高耐压的替代,可在 PANJIT 产品线或其他厂商的 Schottky 产品中查找相近 Vf/Ifsm/VR 的型号,或考虑桥堆、肖特基桥、肖特基同步整流器等替代方案。

六、结论

MBR3H60MB_R1_00001 以其低正向压降、较小的反向漏电、良好的浪涌承受能力与宽温度特性,是一款适合中小功率整流与保护用途的可靠器件。在选用时请结合系统的热设计、浪涌特性与工作电压裕量进行验证,确保长期可靠运行。若需更详细的参数曲线、封装图或回流焊温度曲线,可参考 PANJIT 的官方数据手册或联系器件供应商获取完整技术资料。

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
