GBU2510 产品概述

一、产品简介

GBU2510 是东沃(DOWO)推出的一款单相整流桥二极管,封装为 GBU 系列,面向印刷电路板(PCB)安装的高可靠性整流应用。该器件提供高达 1kV 的直流反向耐压与 25A 的整流电流能力,适用于交流整流、滤波与直流供电模块中对高电压和中高电流的需求场景。

二、主要参数

  • 型号:GBU2510(品牌:DOWO / 东沃)
  • 正向压降 Vf:1.1V @ 12.5A
  • 直流反向耐压 Vr:1000V
  • 整流电流(平均):25A
  • 反向电流 Ir:10µA(典型)
  • 非重复峰值浪涌电流 Ifsm:240A
  • 工作结温范围:-55℃ ~ +150℃
  • 类型:单相整流桥
  • 封装:GBU(PCB 安装)

三、关键特性

  • PCB 贴装设计,便于自动化装配与高密度布局。
  • 外壳塑料材料符合 UL 94V-0 阻燃认证,提升整机安全性。
  • 内置印刷电路板支撑结构,增强机械稳定性与焊接可靠性。
  • 高外壳介电强度,利于高压隔离应用。
  • 端子和封装经过高温焊接可靠性保证:在 5 lbs(约 2.3 kg)拉力下可耐 260℃/5s 的高温焊接工艺。

四、典型应用

  • 单相整流电源与桥式整流模块
  • 开关电源输入整流、滤波电路
  • 充电器、电池管理整流部分
  • 家用及工业电器的直流供电转换
  • LED 驱动与控制器的整流级

五、设计与散热建议

  • 在长期 25A 工作条件下,应考虑合理的 PCB 铜箔面积或外接散热器以降低结温,确保器件在额定结温内稳定工作。
  • 在进行浪涌(Ifsm)测算时,注意 240A 为非重复峰值,短路或过载情况下需配合熔断保护或限流设计。
  • 布线建议采用尽可能短而宽的走线,多层板可通过过孔连接大面积散热铜箔以提升散热能力。
  • 1kV 反压场合应留意爬电距离与空气间隙设计,配合外壳介电特性满足系统安全等级。

六、安装与可靠性

  • 推荐使用波峰/回流焊工艺,器件经过 260℃/5s 的焊接强度验证;在装配时仍应遵循厂商的焊接曲线与 PCB 处理规范。
  • 储存与回流前请保持干燥环境,防止吸湿导致焊接缺陷;长期储存应遵守湿度敏感等级(MSL)相关要求。
  • 工作温度范围宽(-55℃~+150℃),适用于工业级温度环境,但高温下反向漏电流会增加,应在热设计中予以控制。

七、使用注意事项

  • 设计时预留可靠的过流保护与过压抑制措施,避免重复过载缩短寿命。
  • 按照 PCB 布局最佳实践布置 AC 输入端与负载端,减少环路阻抗以降低 EMI 与功率损耗。
  • 对于对效率和发热敏感的应用,可并联多只器件或选用更低 Vf 的替代型号,但需均流设计。

GBU2510 结合高压耐受、较大整流能力与工业级可靠性,适合需要在有限 PCB 空间内实现稳健整流的电源与控制类产品。根据实际应用场景,配合适当的热管理与保护电路可获得长期稳定的工作表现。

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
