ER3J_R1_00001 产品概述

一、产品简介

ER3J_R1_00001 是强茂(PANJIT)推出的一款通用整流二极管,采用 DO-214AB(SMC)表面贴装封装,面向中等功率整流与浪涌保护场合设计。器件具有较高的反向耐压、较低的正向压降和优良的浪涌承受能力,适用于开关电源、适配器及一般整流电路中的整流或保护用途。

二、主要电气参数

该型号的关键电气指标如下(以制造商标注为准):

  • 型号:ER3J_R1_00001
  • 品牌:PANJIT(强茂)
  • 封装:DO-214AB(SMC,表面贴装)
  • 正向压降 Vf:1.7 V @ IF = 3 A
  • 直流反向耐压 Vr:600 V
  • 额定整流电流(平均):3 A
  • 反向电流 Ir:1 µA(在额定耐压条件下的典型/最大量级)
  • 非重复峰值浪涌电流 Ifsm:100 A(在制造商规定的浪涌条件下测定)
  • 工作结温范围:-55 ℃ ~ +150 ℃

以上参数用于器件的基本选型与可靠性评估,实际电路中应参考制造商完整数据手册的测试条件与曲线。

三、封装与机械特性

  • DO-214AB(SMC)为标准化的表面贴装整流二极管封装,便于自动贴装与回流焊工艺。
  • 封装尺寸和引脚布局适合常见的 PCB 足迹,可通过适当的铜箔面积实现散热。
  • 适合批量生产的贴片工艺,减少手工焊接造成的一致性问题。

四、性能与优势

  • 高耐压:600V 的反向耐压使其可应用于高电压整流场合,如离线开关电源的二次或一次侧整流。
  • 中等电流能力:3A 的整流电流满足中功率应用的持续整流需求。
  • 低正向压降:Vf=1.7V(3A)在降低导通损耗和系统发热方面具有一定优势。
  • 优良的浪涌承受力:100A 的峰值浪涌能力可承受启动或短时冲击电流(需按制造商浪涌曲线确认实际测试条件)。
  • 宽工作温度:-55℃~+150℃ 的结温范围适应工业级环境。

五、典型应用场景

  • 开关电源整流(一次侧/二次侧,视电压等级而定)
  • 电池充电器与适配器输出整流
  • 工业电源模块、功率模块的二极管整流与保护
  • 电机驱动、继电器线圈等感性负载的续流或钳位保护(需注意恢复特性)
  • 浪涌吸收、输入整流与反向保护电路

六、使用与散热建议

  • PCB布线:为降低结温,建议在二极管焊盘下及周围布置适量的敷铜/散热铜箔,并在必要时采用多层铜通孔连接散热层。
  • 环境与散热:连续工作时应关注周围温度与功率耗散,必要时进行电流或温度降额处理以保证长期可靠性。
  • 浪涌管理:虽然器件具备较高浪涌能力,但对于频繁或持续的大浪涌环境,应采取限流、电流吸收或使用更高规格浪涌器件的措施。
  • 并联使用:若需并联提升电流能力,应通过电阻或热均衡设计保证电流均分,直接并联一般不推荐。

七、选型与替代参考

  • 若系统电压、纹波或浪涌更高,应向上选择更高耐压或更大平均/脉冲电流能力的器件。
  • 对于要求更低正向压降或更快恢复时间的场合,可考虑肖特基二极管或快速恢复二极管,但需权衡耐压和反向漏电流特性。
  • 选型时注意查看完整的数据手册,确认测试条件(如温度、浪涌脉冲波形、测量点等)与系统需求一致。

八、可靠性与测试要点

  • 常规应进行焊接工艺兼容性验证(回流曲线、焊盘设计)。
  • 对长期可靠性关注结温循环、热冲击与高温储存性能。
  • 在关键应用中应做浪涌、反向恢复及热应力测试,并按照实际负载工况验证温升和寿命。

九、订购与注意事项

  • 型号全称:ER3J_R1_00001,品牌 PANJIT(强茂),封装 DO-214AB(SMC)。
  • 购买时确认批次与数据手册版本,必要时向供应商索取样品与可靠性文档。
  • 在设计资料或生产中引用参数时,推荐以制造商最新版规格书为准,保证测试条件和应用一致。

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.
