GBJ2510 产品概述

一、产品简介

GBJ2510 为 DOWO(东沃)推出的一款单相桥式整流器,采用 GBJ 封装,专为印刷电路板(PCB)安装设计。器件在高压、高电流工作条件下表现稳定,适合工业电源和商用电源整流应用。

二、主要参数

  • 正向压降(Vf):1.1V @ 12.5A
  • 直流反向耐压(Vr):1kV
  • 额定整流电流:20A
  • 非重复峰值浪涌电流(Ifsm):350A
  • 反向漏电流(Ir):10μA
  • 工作结温范围:-55℃ ~ +150℃
  • 类型:单相整流(桥式)
  • 品牌:DOWO(东沃)
  • 封装:GBJ

三、结构与封装特点

GBJ2510 采用标准 GBJ 桥式外壳,塑料材料达到 UL 94V-0 阻燃等级,外壳在电气绝缘及机械强度上经过优化。产品内置 PCB 支撑结构,方便 SMT/THD 混合组装时的定位与焊接可靠性。

四、电气性能亮点

本型号在 12.5A 工作点下具有较低的正向压降(1.1V),在高压环境下直流反向耐压可达 1kV,适合高压整流需求。反向漏电流控制在 10μA 级别,有利于降低待机功耗与系统热损失。350A 的峰值浪涌能力保证了对瞬态冲击的耐受性。

五、热性能与可靠性

器件允许的结温范围宽(-55℃ 至 +150℃),满足严苛环境下的长期运行。塑料外壳与内部封装材料均通过高温焊接测试:在 260℃ 下焊接 5 秒并能承受 5 磅(约 2.3 千克)拉力,确保焊点与引脚的机械可靠性。此外,外壳具有高介电强度,适合高压场景的安全隔离要求。

六、安装与焊接建议

GBJ2510 设计用于 PCB 固定安装,推荐在布局时预留相应的散热铜箔与通孔,改善散热路径。焊接过程中遵循回流/波峰温度曲线,避免超过规定的热循环次数与峰值温度。利用器件自带的 PCB 支撑位置可提高贴装一致性与焊接强度。

七、典型应用场景

  • 开关电源与线性电源整流单元
  • 工业控制与驱动电源(伺服、变频)
  • 电池充电器与不间断电源(UPS)
  • LED 驱动与照明电源
  • 高压整流模块与电力设备

八、选型与注意事项

在选型时请确认实际工作电流与散热条件是否满足 20A 长期整流能力;若环境温度较高或散热条件受限,应适当 derating(降额)使用。高压应用时注意 PCB 流程间距与绝缘措施,以符合安全规范。如需更高浪涌能力或更低正向压降,可联系供应商索取同系列其它型号参数表。

如需样品、详细原理图封装尺寸或进一步的可靠性试验数据,可向 DOWO(东沃)或授权代理咨询。

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
