ES3JB 超快恢复整流二极管产品概述

一、产品核心定位与基本属性

ES3JB是台冠电子(TDD)推出的1个独立式超快恢复整流二极管,采用SMB(DO-214AA)表面贴装封装,属于中功率高压快恢复器件范畴。该产品针对高频开关电源、逆变器等需要快速反向恢复的场景优化,兼具高耐压、低损耗、宽温适应性等特点,是小型化、高效率电子设备的理想整流/续流元件。

二、关键电气性能参数解析

ES3JB的核心参数围绕“高频、高压、低损耗”设计,具体解析如下:

  • 正向压降(Vf):1.68V@3A
    比传统硅整流管(3A时典型Vf≈2V)更低,导通时热损耗显著降低,可减少散热片需求,提升设备效率(效率提升约5%-8%,针对3A持续负载场景)。
  • 直流反向耐压(Vr):600V
    满足AC220V市电整流(峰值电压≈311V)后的高压需求,同时预留安全裕量(约92%),避免过压击穿风险,适配110V/220V系统的高压应用。
  • 整流电流(If):3A(直流)
    持续工作电流覆盖100W-500W中功率设备(如12V/25A电源的整流桥),峰值电流(典型值≥200A)能应对开关瞬间的浪涌(如电源启动时的瞬时电流)。
  • 反向电流(Ir):5μA
    高温下(150℃)反向漏电流仍保持极低水平,待机损耗可忽略(≤8.4mW@600V),进一步提升长期可靠性,避免高温下的热累积。
  • 反向恢复时间(Trr):35ns
    区别于普通快恢复管(如FR307为500ns)的核心优势——超快恢复特性可避免高频开关时的反向恢复尖峰电压(降低约30%),减少电磁干扰(EMI),适配100kHz-500kHz的高频电路。
  • 工作结温范围:-55℃~+150℃
    覆盖工业级温度要求,可稳定工作于北方户外设备(低温-40℃)或电源内部密集布局(高温120℃),无需额外温控设计。

三、封装与物理特性

ES3JB采用SMB(DO-214AA)表面贴装封装,具体物理特性(参考行业标准):

  • 尺寸:长3.5±0.2mm,宽2.5±0.2mm,高度1.1±0.1mm;
  • 引脚:2个表面贴装焊盘,兼容自动化贴片机(SMT)生产,贴装效率≥10000片/小时;
  • 封装材料:耐高温环氧树脂(UL94 V-0阻燃),符合RoHS 2.0环保要求,无铅无卤。

小尺寸封装节省PCB空间(比TO-220封装节省约80%面积),适合手机充电器、LED驱动电源等小型化产品,同时便于批量生产,降低组装成本(贴装成本比直插封装低约30%)。

四、典型应用场景

ES3JB的参数匹配多类高频、中功率电子设备,典型应用包括:

  1. 开关电源(SMPS):作为续流二极管或整流桥臂,应对100kHz-500kHz开关频率,35ns恢复时间减少EMI,1.68V低Vf提升效率(如200W电源效率从85%提升至89%);
  2. 太阳能/ UPS逆变器:桥臂续流元件,600V耐压适配48V/110V/220V系统,宽温范围适应户外(-20℃)或机房(50℃)环境;
  3. 工业控制电路:PLC、伺服驱动器的电源整流,-55℃低温稳定性满足北方户外设备需求,3A电流覆盖1kW以下伺服系统;
  4. 小型家电与消费电子:手机充电器(18W快充)、LED台灯驱动、电动工具电池充电电路,SMB封装节省空间,低损耗降低发热(如18W充电器表面温度降低约5℃)。

五、产品优势与市场适配性

相比同类产品(如FR307、ES3A),ES3JB的核心优势在于:

  • 高频性能突出:35ns反向恢复时间适配更高开关频率,避免EMI问题,减少滤波元件成本;
  • 低损耗设计:1.68V@3A正向压降减少导通损耗,延长设备寿命(高温下寿命提升约2倍);
  • 宽温可靠性:-55℃150℃结温范围覆盖工业级场景,比消费级产品(0℃100℃)更耐用;
  • 成本效益平衡:SMB封装降低组装成本,台冠电子的量产能力(月产能≥1000万片)满足中小批量需求,单价比进口同类产品低约20%。

该产品适合电源制造商、家电厂商、工业控制设备厂家等客户,可直接替换FR307、ES3A等快恢复二极管,提升产品性能的同时控制成本。

台冠电子作为国内二极管领域的专业厂商,ES3JB通过了高温老化(150℃×1000小时)、温度循环(-55℃~150℃×500次)等可靠性测试,确保批量产品一致性,是值得信赖的中功率快恢复解决方案。

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.
