2W10 单相整流桥(DIP-4)产品概述

一、产品简介

2W10 是 DOWO(东沃)提供的一款单相整流桥,采用四脚直插式(DIP-4)封装,额定整流电流为 2A,直流反向耐压高达 1000V,适用于中高压、小功率的交流—直流整流场合。器件工作结温范围宽,能在-55℃至+150℃温度区间稳定工作,适应工业级应用环境。

二、主要技术参数

  • 整流电流(IF(AV)):2A(连续)
  • 非重复峰值浪涌电流(IFSM):30A(典型按 8.3ms 半正弦波)
  • 直流反向耐压(VR):1000V(1kV)
  • 正向压降(Vf):1.1V @ 2A(单只二极管)
  • 反向电流(IR):≤10µA(典型在 25℃ 下)
  • 工作结温:-55℃ ~ +150℃
  • 封装:DIP-4,四引脚直插型
  • 类型:单相桥式整流

三、特性与优点

  • 高耐压:1kV 的反向耐压使其适合用于较高电压的整流场景。
  • 稳定的整流能力:2A 连续整流适合中小功率电源与偏压电路。
  • 良好的浪涌承受能力:30A 的非重复峰值浪涌电流保证器件在启动或短时冲击电流下有一定裕量。
  • 宽工作温度范围:工业级温度范围满足严苛环境要求。
  • 直插封装易于手工装配和维护,便于快速打样和小批量生产。

四、热量与功耗评估

在 2A 连续工作条件下,单只二极管正向压降约为 1.1V,则单个二极管耗散约 2.2W,桥式整流时同时有两只二极管导通,总耗散约 4.4W。该热量对封装和 PCB 散热要求较高,建议通过增大 PCB 铜箔面积、合理布局以及必要时加入散热片或风冷以保证结温在安全范围内。实际使用时应参考厂方的电流-温度降额曲线进行降额设计。

五、典型应用场景

  • 工业电源与控制设备中的中高压整流模块
  • 仪器仪表、检测设备的高压偏置电源
  • 开关电源辅助电路、整流与滤波前端
  • 继电器驱动、电磁阀供电等需耐受浪涌的应用
  • 电子教具、原型开发与小批量产品中常用的直插整流器

六、选型与使用建议

  • 若工作电流长期接近 2A,应考虑降额使用或改善散热以延长寿命。
  • 对于频繁出现大电流冲击的场合,确认 IFSM 的规格与实际浪涌波形(常用 8.3ms 半正弦波)一致,必要时选择更高浪涌能力的型号或并联器件(并联需注意电流均流)。
  • 反向电流 IR 会随温度上升显著增加,长期高温环境下需评估漏电对系统的影响。
  • 由于正向压降较大(每只约 1.1V),在高效率要求场合考虑低 Vf 或同步整流方案。

七、封装与焊接注意事项

DIP-4 直插封装便于穿孔安装与手工焊接。焊接时遵循常规波峰/手工焊工艺,避免过长高温暴露,防止封装材料劣化。推荐在 PCB 上为整流桥预留足够的铜面积以利散热,并避免与温度敏感元件紧邻布置。具体引脚定义及焊接温度上限请参照 DOWO 的官方数据手册。

八、可靠性与质量控制

建议在设计验证阶段进行温升与寿命测试,包含高温/高湿、温度循环及浪涌耐受测试。对关键应用可要求厂方提供批次质量保证与相关检验报告。长期可靠性与低故障率依赖于合理的热管理与符合规范的电气降额设计。

九、采购与资料

品牌:DOWO(东沃);封装:DIP-4;型号:2W10。欲获取完整电气特性曲线、引脚图与降额曲线,请向供应商索取最新数据手册与样片进行验证。若需替代型号或更高性能规格,可在保证电压、电流及包装适配性的前提下比较 Vf、IFSM 与热阻等参数进行选型。

以上为 2W10 的简要概述与工程应用建议,供设计与选型参考。若需具体的电气曲线、封装图或降额曲线,可提供后续资料获取渠道或直接联系供应商索取原厂数据手册。

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.
