MB10S单相整流桥产品概述

一、产品基本定位与封装形式

MB10S是一款单相桥式整流器,由DOWO(东沃)电子推出,采用MBS(Miniature Bridge Rectifier Surface Mount)表面贴装封装。该封装体积小巧(适配标准SMT引脚布局),既支持自动化贴装生产线,又具备良好的散热与机械稳定性,适合对空间紧凑性要求较高的电子设备设计。产品定位为小功率高压整流通用器件,核心功能是将交流输入(AC)高效转换为直流输出(DC),覆盖多场景基础电源需求。

二、核心电气性能参数解析

MB10S的参数经过优化,兼顾性能与可靠性,关键指标可支撑多种应用场景:

  • 正向压降(Vf):1.05V@400mA(典型值)。低压降是核心优势——相比同类1kV耐压整流桥,可降低整流损耗约10%-15%,减少整机发热,提升电源转换效率;
  • 直流反向耐压(Vr):1000V(连续工作电压)。满足高压AC输入(如220V/380V市电,需考虑峰值裕量)的反向阻断需求,避免器件击穿;
  • 最大整流电流(If):800mA(连续值)。稳定承载0.8A直流输出,适配10W-20W小功率电源的前端整流;
  • 反向漏电流(Ir):10μA@1kV(典型值)。漏电流极小,反向工作时无明显功率损耗,长期运行稳定性佳;
  • 非重复峰值浪涌电流(Ifsm):30A(8.3ms半波脉冲)。能承受开机瞬间或负载突变的大电流冲击,提升设备抗干扰能力;
  • 工作结温范围:-55℃至+150℃。宽温度覆盖适配工业级、极端环境(如低温户外、高温密闭机箱)应用,无需额外降额设计。

三、典型应用场景

MB10S因参数均衡,广泛落地于以下领域:

  1. 家电控制板:微波炉、电磁炉、空调的电源模块,实现220V AC到低压DC的整流;
  2. 小功率电源适配器:手机充电器、LED驱动电源的前端AC-DC转换(适配10W-20W功率段);
  3. 工业控制模块:小型PLC、传感器节点、继电器驱动板的电源单元(支持1kV以下高压输入);
  4. 照明设备:LED路灯、室内LED照明的驱动电源整流部分(满足低损耗、高可靠性要求)。

四、可靠性与环境适应性特点

  • 宽温耐受:-55℃至+150℃结温范围,可在北方户外低温、密闭机箱高温等场景稳定工作;
  • 抗浪涌能力:30A非重复浪涌电流符合IEC 61000-4-5电磁兼容标准,避免开机冲击损坏;
  • 封装可靠性:MBS封装采用环氧树脂灌封,防潮、防振动性能优异,兼容回流焊/波峰焊工艺;
  • 低损耗设计:低正向压降+低漏电流结合,长期工作发热小,延长器件与整机寿命。

五、品牌与品质保障

DOWO(东沃)作为国内整流器件专业厂商,MB10S通过严格品质管控:

  • 符合RoHS 2.0环保标准,无铅封装;
  • 批量前经高低温循环、湿热老化等可靠性测试;
  • 批次一致性高,参数离散性小,适配自动化生产;
  • 提供完整datasheet与技术支持,满足客户设计验证需求。

MB10S以“小体积、高压耐、低损耗”为核心竞争力,是小功率高压整流场景的高性价比选择。

Sourcing availability signal

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
