MB10F 整流桥(MBF 封装)产品概述

一、产品简介

MB10F 为晶导微电子出品的单相整流桥,MBF 封装,面向高压整流与中小功率直流供电场景。器件在工作结温范围广(-55 ℃ ~ +150 ℃,Tj),具备高阻断电压与较低的正向压降,适用于需要高耐压且对反向漏电流敏感的电源设计。

二、主要参数

  • 类型:单相整流桥(桥式整流器)
  • 正向压降(Vf):1.1 V @ 800 mA(单个二极管)
  • 整流电流:800 mA(连续)
  • 非重复峰值浪涌电流(Ifsm):30 A(单次冲击)
  • 直流反向耐压(Vr):1000 V(Vrwm / Vrrm)
  • 反向电流(Ir):5 μA @ 1000 V
  • 工作结温:-55 ℃ ~ +150 ℃(Tj)
  • 封装:MBF

注:桥式工作时,每次导通存在两只二极管串联的压降。

三、关键性能解析

  • 高耐压特性:1000 V 的反向耐压使 MB10F 适合高压整流场合,例如高电压电源、测试设备或 HV 传感器供电,能承受较大的直流阻断电压。
  • 低反向漏电:在 1000 V 条件下反向电流仅为 5 μA,适用于对漏电流要求严格的应用(例如计量、仪器仪表及高阻输入电路)。
  • 正向压降与功耗:单片二极管 Vf 为 1.1 V(@800 mA),桥式整流时有效电压降约为两只二极管之和,即约 2.2 V。示例功耗:在 0.8 A 时 P ≈ 2.2 V × 0.8 A ≈ 1.76 W,需注意热管理。
  • 冲击能力:Ifsm 30 A 表明器件可承受短时电流冲击(如开机浪涌或容性负载充电),但不宜作为长期超过额定电流的工作方式。

四、热设计与散热注意事项

  • 由于在额定整流电流下器件功耗接近几瓦,建议在 PCB 设计中预留较大铜箔面积或增加散热片 / 对流散热,保证结温低于 150 ℃。
  • 在高环境温度或封装限制的场合,应考虑对整流电流进行降额处理(derating),以延长寿命并提高可靠性。
  • 反向漏电流随温度上升而增大,高温条件下要留有余量并评估系统电流容忍度。

五、典型应用场景

  • 高压整流电源(实验室电源、HV 传感器供电)
  • 工业电源模块中的整流与整流保护
  • 仪器仪表与计量设备(低漏电高阻断需求)
  • 小功率开关电源输入整流、备用电源与电池充电(中等电流)
  • 对浪涌有一定要求的电源(结合抑制元件使用)

六、使用与保护建议

  • 对于含有大电容的输入滤波器或需承受较大浪涌的应用,建议在输入端加入限流电阻、NTC 启动电阻或软启动电路以限制 Ifsm。
  • 在高压侧使用时,留有足够的边缘间隙与爬电距离,确保耐压与绝缘安全。
  • 若系统对反向漏电极其敏感,应在实际温度条件下验证漏电水平,并考虑冗余或后备测量/检测电路。
  • 对于长期运行的设计,建议将工作电流控制在额定值以下,参照供应商资料做电流降额。

七、封装与焊接提示

  • MBF 封装适合 PCB 插装,焊接时注意焊接温度与时间,避免对封装和内部焊点造成热损伤。
  • PCB 布局应保证桥输出端与散热铜箔良好连接,并根据实际功耗设计足够的铜面与通孔散热路径。
  • 为保证长期可靠性,推荐按照行业焊接与清洗规范进行生产工艺控制。

八、可靠性与测试建议

  • 在产品开发阶段,开展热循环测试、耐压测试(Hi-Pot)、浪涌测试(Ifsm)、湿热与盐雾等可靠性验证,确认在目标应用环境下性能满足要求。
  • 对批量采购,建议抽检反向漏电、正向压降与耐压一致性,确保器件批次稳定。

九、选型建议

若应用需要高耐压(≥1000 V)、低漏电且中等整流电流(≤800 mA),MB10F 是合适的选择。对于更高持续电流或更低正向压降的需求,可考虑更大封装或肖特基器件,但需权衡漏电与耐压指标。最终选型应结合实际工作温度、浪涌条件、功耗散热方案以及系统安全裕度综合评估。

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.
