KBPC5010(MDD)产品概述

一、产品简介

KBPC5010 是由 MDD 提供的一款单相整流桥,采用 KBPC 塑封金属外壳封装,面向工业级高电压、大电流整流场合设计。器件具有高峰值浪涌能力、低反向漏电流和宽工作结温范围,适合对可靠性和散热有较高要求的电源整流、逆变与工业设备。

二、主要电气参数

  • 型号:KBPC5010(品牌:MDD,封装:KBPC)
  • 直流反向耐压 Vr:1000 V
  • 整流电流(平均):50 A
  • 正向压降 Vf:1.1 V(测试点:25 A,单只二极管)
  • 非重复峰值浪涌电流 Ifsm:400 A(典型 8.3 ms 半波冲击条件)
  • 反向电流 Ir:10 μA @ 1 kV
  • 工作结温范围 Tj:-65 ℃ ~ +150 ℃
  • 类型:单相桥式整流

三、关键特性与优势

  • 高电压耐受:1000 V 的反向耐压适用于高压整流和高电压隔离电源。
  • 大电流能力:50 A 的平均整流能力配合 400 A 的浪涌承受能力,能应对启动浪涌和短时过载。
  • 低漏电流:10 μA @1 kV 的低反向电流有利于高阻接地或高压测量系统,降低静态损耗。
  • 宽温区稳定性:-65 ℃ 至 +150 ℃ 的结温范围满足极端环境与工业级应用要求。
  • 散热友好封装:KBPC 金属顶盖带安装孔,便于直接安装到散热片上,提高热阻管理效率。

四、热管理与安装建议

  • 封装导热性良好,但在 50 A 等效工作电流下损耗显著(单只二极管 25 A 时 Vf≈1.1 V,桥式导通时输出端通常有两只二极管导通);务必使用足够面积和接触良好的散热片,并考虑空气流动或强制风冷。
  • 建议在实际设计中进行热仿真并对整流电流进行降额处理,保证结温远低于上限以延长寿命。
  • 安装时使用合适的绝缘垫圈或薄片(如需电气隔离)并保证螺丝力矩均匀以获得良好热接触。
  • 对于开关电源或含有高频脉冲的系统,建议在输入端并联适当的保险和浪涌抑制器(NTC、TVS 或 RC 吸收网)以保护整流桥免受重复冲击。

五、典型应用场景

  • 交流到直流电源(线性或开关电源)的大功率整流。
  • 电池充电机与电源备份(UPS)系统的主整流或再整流环节。
  • 工业电机驱动、焊机、感应加热及变频器等含高浪涌或高电压的场合。
  • 高压测试设备与测量仪器中需要低漏电流的整流模块。

六、选型与注意事项

  • 若系统连续工作电流接近或超过额定值,应选择更高额定电流或并联多片整流桥,并注意电流均分问题。
  • Vf 给出的是在 25 A 下的典型值,实际在更高电流与更高温度下将增大,需计算额定损耗并设计足够散热。
  • Ifsm 为非重复峰值浪涌能力,非长期承受,频繁的冲击会缩短器件寿命。
  • 在高压应用中,注意端子与周边元件的爬电距离及绝缘等级,防止放电和击穿。

七、结论

MDD 的 KBPC5010 是一款适合高压、大电流、工业级应用的单相整流桥。凭借 1000 V 的耐压、50 A 的整流电流、低漏电流与良好的浪涌承受能力,适用于多种高可靠性电源场合。设计时应重视热管理与浪涌保护,以发挥其最佳性能并保证长期可靠运行。若需更详细的机械尺寸、封装图或温升数据,建议参考厂商完整数据手册或联系供应商索取。

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
