MB10S 产品概述

一、产品简介

MB10S 是 TWGMC(台湾迪嘉)提供的一款单相整流桥,面向需要高反向耐压与低正向压降的小功率整流场合。该器件在高电压条件下具有极低的反向漏电(5µA@1kV),并在中小电流工作点表现出较低的正向压降(1V@400mA),适合高压微功率直流电源与隔离供电电路使用。

二、主要性能参数

  • 类型:单相整流桥
  • 工作结温范围:-55℃ ~ +150℃
  • 直流整流电流:800mA(标称)
  • 正向压降 (Vf):1V @ 400mA
  • 非重复峰值浪涌电流 (Ifsm):30A(短时浪涌能力)
  • 直流反向耐压 (Vr):1kV
  • 反向电流 (Ir):5µA @ 1kV
  • 封装:MBS
    以上参数为器件典型与标称值,具体使用时请参照厂家完整数据手册以确认测试条件与限值。

三、封装与引脚

MB10S 采用 MBS 塑封桥式封装,结构紧凑、四引脚布局,便于直接插装或表面贴装焊接到 PCB。该封装利于批量生产与自动化装配,适用于空间受限的电路板设计。具体引脚排列与外形尺寸请参照厂家机械图纸。

四、适用场景

  • 高压小电流整流:需要 1kV 反向耐压、低漏电的高压电源模块。
  • 测试与测量设备:高压偏置、传感器供电、示波器前端等。
  • 工业与仪表:隔离电源、低功率控制电路。
  • 消费电子:小型充电器、驱动电路以及某些 LED 驱动应用(需考虑功率与热管理)。

五、使用与热管理建议

  • 整流电流 800mA 为器件的连续标称值,但实际可用性受 PCB 散热、环境温度与通风影响。高结温会造成正向压降与反向漏电增加,应尽量控制结温在安全范围内。
  • 遇到高浪涌或频繁充放电的场合,考虑外加浪涌抑制(NTC、限流电阻或软启动电路)以保护整流桥。
  • 反向漏电随温度显著上升,在高温或高反向电压下应验证漏电是否满足系统要求。

六、典型电路与保护措施

  • 常见用法为单相桥式整流:交流输入接桥的两个交流端,桥正负输出经过滤波电容及后级稳压处理得到直流。
  • 推荐在交流输入侧加熔断器或自恢复保险丝,以及 TVS 或 MOV 做瞬态抑制,以应对雷击或浪涌。
  • 对于电解电容直充场合,应限制初始充电电流,避免超过器件 Ifsm 规定值(30A),延长器件寿命。

七、品质与采购信息

MB10S(TWGMC 台湾迪嘉)适合在需要长期稳定工作的工业级应用中使用,-55℃~+150℃ 的结温范围指示其在苛刻环境下的可靠性。采购时请确认产品为原厂或授权代理供应,并索取最新规格书和质量合格证明。

八、注意事项与检验建议

  • 设计工程师须根据实际工作环境(温度、散热条件、最大反向电压、浪涌频率等)进行热仿真与应力验证。
  • 在高压应用中,布局要保证足够爬电距离与绝缘强度;测试时按不同温度点测量反向漏电以确认安全裕量。
  • 焊接与回流工艺请遵循厂家推荐曲线,避免过热导致器件损伤。

总结:MB10S 以其高达 1kV 的反向耐压、低反向漏电与较低正向压降,适用于高压低功率整流场合。合理的热管理与浪涌保护是保证器件长期可靠工作的关键。

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
