MB10F 产品概述

一、产品简介

MB10F 是友台半导体(UMW)提供的一款单相整流桥,采用 SOP-4 封装,面向体积受限且需高耐压的小功率直流电源应用。器件直流反向耐压达 1kV,整流电流额定 800mA,反向电流仅 5µA,能够满足工业、通信及白色家电中对高耐压与低漏电的要求。

二、关键电气参数

  • 直流反向耐压 (Vr):1 kV,适合高压输入或高压浪涌场合。
  • 整流电流:800 mA(连续),适用于小型电源或辅助供电。
  • 反向电流 (Ir):5 µA(典型/最大),在高温下仍保持较低泄漏。
  • 非重复峰值浪涌电流 (Ifsm):30 A(单次浪涌),能承受开机或短时冲击电流。
  • 工作结温范围:-55 ℃ ~ +150 ℃,适应工业级温度环境。
  • 类型:单相整流桥,封装:SOP-4。

三、结构与封装

SOP-4 小型塑封四引脚设计,便于表面贴装(SMT)生产。封装占板面积小,适合紧凑型电路板布局。封装内含四只硅二极管组成桥式整流结构,常见引脚为两引脚接交流输入,另两引脚为正负直流输出(具体管脚请参考厂方数据手册)。

四、性能与优势

  • 高耐压:1kV 的反向耐压使器件在高压线路或有较大瞬态电压的环境中更可靠。
  • 低泄漏:5µA 的低反向电流有利于降低空载功耗和改善高阻抗电路的稳定性。
  • 宽温域:-55~+150 ℃ 的结温范围提升了可靠性与适应性,适合工业级应用。
  • 体积小:SOP-4 表贴封装便于自动化贴装,适合大批量生产。

五、典型应用场景

  • 小功率开关电源的辅助整流或次级整流。
  • 家用电器与仪表的低功率直流供电。
  • 工业控制、传感器前端的整流或极性保护。
  • LED 驱动、充电器、测试设备和高压脉冲电路(需注意浪涌和功耗匹配)。

六、设计与使用建议

  • 散热与功率损耗:按实际电流和二极管正向压降估算功耗(桥式整流通常为两只二极管串联导通,正向压降约为两倍单只 Vf),在连续 800 mA 工作时需评估 PCB 散热能力并留足铜箔面积。
  • 冲击与浪涌:Ifsm=30A 能承受短时浪涌,但在频繁大浪涌或雷击环境中,应配合浪涌抑制器(TVS)或限流器使用。
  • 布局注意:尽量缩短交流输入到桥的走线,增大正负输出走线宽度以降低压降与发热。输入侧建议并联电容作滤波,但注意电容耐压等级与极性。
  • 引脚与封装:根据实际 PCB 图与原厂数据手册确认引脚定义,避免接错导致损伤。表面贴装推荐遵循厂方回流焊温度曲线以防封装应力。

七、可靠性与存储

  • 存储时避免潮湿、高温环境,若长期存放建议采用防潮包装并在贴装前进行烘烤除湿(依据湿敏等级)。
  • 推荐在 ESD 管理的环境中处理与装配,以降低静电损伤风险。
  • 在高温或高电压边界工作时,应做适当降额设计以延长器件寿命。

八、选型提示

若应用需要更高连续电流能力或更强浪涌承受能力,可考虑更大电流额定的桥式整流器;若对低压降有较高要求,可优先选用肖特基整流桥。最终选型应以完整数据手册中正向压降、结温系数及封装热阻等参数为准,并结合系统实际工况进行验证。

如需 MB10F 的原厂数据手册、引脚图或典型应用电路,可进一步提供型号要求与应用场景,以便给出更精确的选型与布板建议。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
