GBU4K-BP 产品概述

一、主要参数

GBU4K-BP 为单相整流桥,出自 MCC(美微科),适用于中低功率交流到直流整流场合。关键参数如下:

  • 典型正向压降 Vf = 1.0V @ 2A
  • 直流反向耐压 Vr = 800V
  • 最大整流电流(平均)Io = 4A
  • 反向漏电流 Ir = 5µA @ 800V
  • 非重复峰值浪涌电流 Ifsm = 320A
  • 工作结温范围 Tj = -55°C ~ +150°C
  • 封装形式:GBU(桥式整流封装)

二、产品特性

  • 低正向压降:在 2A 条件下 Vf ≈ 1V,有利于降低整流损耗与发热。
  • 高耐压能力:800V 反向耐压,适合高压输入或跨国电网应用。
  • 小漏电流:5µA@800V 显示出较好的反向绝缘性能,利于减少高压下的待机损耗。
  • 强浪涌承受力:320A 的峰值浪涌电流能够承受较大的开机冲击电流或负载突变。
  • 宽温度范围:-55°C 到 +150°C,适应严苛环境与长寿命工作要求。

三、典型应用

  • 开关电源输入整流(中低功率)
  • LED 驱动电源与照明设备整流模块
  • 小型工业电源、家用电器(电源适配器、充电器)
  • 功率因数校正电路(前端整流)与滤波电路

四、设计与使用注意事项

  • 散热计算:额定平均整流电流 4A 工作时需关注正向压降带来的功耗(例如 2A 时功耗约 2W),长期满流或高频工作建议配合散热片或良好铜箔散热。
  • 浪涌保护:尽管 Ifsm 高达 320A,但在频繁的浪涌环境下仍建议加入限流、电阻或 NTC 抑制器以延长器件寿命。
  • 冷却环境:在高环境温度下应保证良好通风或加装散热结构,以避免结温超过额定范围。
  • 焊接工艺:遵循封装和焊接曲线,避免过热造成封装或引脚应力损伤。

五、封装与安装

GBU 封装为桥式整流常见外形,便于在 PCB 上直接安装与焊接,具有较好的机械强度与引脚布局。根据应用可选择单独安装或配合外部散热片、导热胶使用。

六、可靠性与选型建议

  • 若系统工作电流接近或超过 4A,应考虑留有安全裕量或选型更高电流型号。
  • 对于包含高浪涌或工业电网冲击的场合,优先考虑更高 Ifsm 或增加保护电路。
  • 对于高效率或低发热需求,可对比肖特基整流器件,但需平衡耐压与漏电流要求。

七、结论

GBU4K-BP 以其 800V 耐压、低漏电、较低正向压降和良好浪涌能力,适合中低功率、高压整流场景。选型时结合实际工作电流、散热条件与浪涌特性,可获得稳定可靠的整流解决方案。

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
