ES3J快恢复二极管产品概述

ES3J是江苏长电(CJ)推出的独立式快恢复/高效率二极管,针对中小功率高频整流、续流场景优化设计,具备低正向压降、快速反向恢复、宽温适应等核心优势,广泛应用于电源、LED驱动、逆变器等领域。

一、产品核心定位与类别

ES3J属于快恢复二极管(FRD)范畴,兼具高效率特性——区别于普通整流二极管的慢恢复特性,其35ns反向恢复时间可显著降低高频开关损耗,提升电路效率。作为单管独立式设计,无需并联/串联即可满足3A持续整流需求,适配中小功率系统的紧凑布局要求。

二、关键电气参数详解

ES3J的参数平衡了功率容量与开关性能,核心参数如下:

  1. 正向特性:正向压降(Vf)为1.7V@3A,相比传统硅管在3A持续电流下保持低损耗,减少发热;
  2. 反向耐压:直流反向耐压(Vr)达600V,覆盖220V AC整流(峰值≈311V)及部分380V AC降压整流场景;
  3. 电流能力:持续整流电流(IF)3A,非重复峰值浪涌电流(Ifsm)100A,可承受开机瞬间或负载突变的脉冲冲击;
  4. 开关性能:反向恢复时间(Trr)仅35ns,反向漏电流(Ir)10uA,静态损耗低,适合100kHz以下高频电路;
  5. 温度特性:工作结温范围-55℃~+150℃,适应工业环境宽温变化(如户外LED驱动、车载辅助电源)。

三、封装形式与物理特性

ES3J采用SMBG封装(表面贴装型玻璃钝化封装),具备以下特点:

  • 尺寸紧凑:符合贴片标准,便于自动化贴装,节省PCB空间;
  • 热稳定性:玻璃钝化工艺提升抗潮湿、抗静电能力,适合批量生产与长期使用;
  • 焊接可靠性:适配标准SMD焊盘,无引脚氧化风险,兼容无铅焊接。

四、典型应用场景

ES3J的参数特性适配多类中小功率高频电路:

  1. 开关电源:AC-DC适配器(笔记本、手机快充辅助整流)、DC-DC转换器续流二极管;
  2. LED驱动:户外路灯、室内面板灯的整流/续流,宽温特性适应户外温差;
  3. 逆变器:小型太阳能逆变器、UPS功率回路整流,快恢复降低开关损耗;
  4. 工业控制:PLC模块、传感器电源低功耗整流,浪涌能力抗工业干扰;
  5. 家电:电磁炉、微波炉电源整流,满足小功率高频需求。

五、品牌与可靠性保障

ES3J由江苏长电(CJ)生产,长电作为国内半导体龙头,具备完善品质管控:

  • 符合RoHS、REACH环保标准,无铅焊接兼容;
  • 经过高低温循环、浪涌冲击等可靠性测试,满足工业级要求;
  • 批量供货稳定,封装一致性好,适合量产。

六、选型与使用注意事项

  1. 参数限制:持续电流≤3A,反向电压≤600V,避免过流/过压;
  2. 散热设计:结温上限150℃,需根据负载设计散热(如增加PCB铜箔);
  3. 焊接要求:回流焊温度≤260℃,避免热应力损伤;
  4. 存储防护:存储温度-55℃~+150℃,湿度≤60%RH,需ESD防护。

总结:ES3J以3A/600V、35ns恢复时间为核心优势,结合SMBG封装的紧凑性与长电可靠性,是电源、LED驱动等领域的高性价比选型。

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
