E1J 产品概述

一、产品简介

E1J 是 GOODWORK(固得沃克)推出的一款独立式快恢复/高效率二极管,采用 SOD-123FL 小型表面贴装封装,面向需要高电压阻断和中等开关速度的电源及功率转换应用。器件额定直流整流电流 1A,反向耐压高达 600V,结合较低的反向漏电和短的反向恢复时间,适合用于中高压开关电源、续流整流和保护电路等场合。

二、主要性能特点

  • 高电压阻断:直流反向耐压 Vr = 600 V,适合 400V/600V 级别电源和逆变器使用。
  • 中等正向压降:正向压降 Vf = 1.7 V(@1 A),在保证高压等级的同时实现较高效率的整流。
  • 低漏电流:反向电流 Ir = 5 μA(@600 V),在高压工作下能有效降低空载或待机损耗。
  • 快恢复特性:反向恢复时间 Trr = 35 ns,能在中高频开关场合减小开关损耗和过冲。
  • 抗浪涌能力:非重复峰值浪涌电流 Ifsm = 30 A(单脉冲),可承受短时突发电流冲击。
  • 宽温度范围:工作结温范围 Tj = -65 ℃ 至 +150 ℃,适应严苛环境和温度变化大的应用。
  • 小型封装:SOD-123FL,适合高密度 PCB 布局与自动化贴片加工。

三、电气与热性能要点

  • 正向功耗估算:在额定整流电流 1 A 条件下,器件正向压降约 1.7 V,对应正向功耗约 1.7 W(不包含寄生与环境影响)。在设计时需预留足够的散热路径以避免结温超标。
  • 反向恢复与开关损耗:Trr = 35 ns 属于快恢复二极管范畴,对中等开关频率(几 kHz 到数百 kHz,取决于电路拓扑)有良好适配性;在极高频(MHz 级)应用上可能被更快的器件(如快速肖特基)替代。
  • 浪涌处理:Ifsm=30 A 表示可承受短时峰值冲击(如整流桥的浪涌或启动冲击),但不宜作为长期重复过载使用,需按实际浪涌波形与能量进行评估。
  • 温度与电流降额:在高结温下器件额定电流需相应降额,推荐根据具体 PCB 铜箔面积与热阻进行热设计与电流能力验证。

四、典型应用场景

  • 开关电源(SMPS)中的整流与续流二极管。
  • 电机驱动与逆变器中的快恢复整流与保护回路。
  • 功率因数校正(PFC)电路的中压整流单元。
  • 家电与工业电源的高压整流、反向防护及浪涌抑制。
  • 需要高阻断电压但又要求快恢复、高效率整流的混合应用场合。

五、封装与装配建议

  • SOD-123FL 为低剖面 SMD 封装,适合自动贴装与回流焊工艺。回流温度曲线应按封装和无铅工艺规范控制,避免长时间高温超出器件热限。
  • 布局建议:二极管的走线尽量短且粗,降低寄生电感;在高频开关回路中,二极管附近地回流路径应尽量短且完整,以减少电压尖峰和 EMI。
  • 散热建议:为保证长期可靠性,在 PCB 上为二极管负载端增加铜箔面积或使用散热过孔;在高负载或高环境温度下进行热仿真或实测验证。

六、可靠性与使用注意事项

  • 避免在超过额定结温范围下长期工作,长期过热会降低寿命并可能导致参数漂移。
  • 虽具备 30 A 非重复峰值浪涌能力,但不应将其作为频繁过载工作的替代方案;对于反复浪涌场合应选择更高浪涌能力或并联/限制电路。
  • 在高频开关场合如出现明显振铃或过电压,应配合 RC 缓冲、共模/差模电感或 TVS 等抑制措施以保护二极管和系统其它元件。

七、订购信息与替代选择

  • 型号:E1J,品牌:GOODWORK(固得沃克),封装:SOD-123FL。该器件为面向高压快恢复整流的标准产品,适用于需要 600 V 阻断与 1 A 整流能力的应用。
  • 替代选择:在需更低正向压降的场合可考虑高压肖特基(但高压肖特基在 600 V 级别选择有限);在需更短恢复时间的高频场合可考虑更高速的快恢复二极管或专用同步整流方案。选择替代产品时请对比 Vr、Vf、Trr、Ir 和 Ifsm 等关键参数并做热/电仿真验证。

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.
