ES2J(SMB封装)超快恢复整流二极管产品概述

ES2J是台冠电子(TDD)推出的单管独立式超快恢复整流二极管,采用SMB(DO-214AA)表面贴装封装,针对中小功率高频开关电路的低损耗、快速响应需求优化设计,核心参数覆盖2A连续整流电流、600V反向耐压及35ns反向恢复时间,适用于开关电源、LED驱动等场景。

一、产品核心定位与应用场景

ES2J定位于中小功率高频整流场景,解决普通整流管反向恢复时间长、损耗高的问题,主要应用于:

  • 开关电源次级整流(如手机充电器、笔记本适配器);
  • LED恒流驱动电源(反激/升压拓扑);
  • 低压逆变器(如太阳能微型逆变器);
  • 通信基站电源模块;
  • 工业控制电源(宽温环境需求)。

其宽温范围(-55℃~+150℃)与小体积封装,可适配小型化、恶劣环境的设备设计。

二、关键电气参数深度解析

1. 整流能力与正向损耗

  • 连续整流电流(If):2A(直流),满足中小功率负载需求,峰值电流支持[email protected](占空比≤1%);
  • 正向压降(Vf):1.68V@2A(25℃),属于同规格快恢复二极管的低损耗水平,2A负载下功率损耗仅3.36W,可有效提升电源效率。

2. 反向耐压与漏电流

  • 直流反向耐压(Vr):600V,覆盖AC220V输入整流后的高压范围(峰值约310V),留有充足安全余量;
  • 反向漏电流(Ir):5uA(25℃、Vr=600V),高温下(125℃)漏电流仍低至100uA以内,反向截止时损耗可忽略,提升电路可靠性。

3. 反向恢复特性

  • 反向恢复时间(Trr):35ns,远优于普通硅整流管(如1N4007的Trr≈300ns),可降低高频开关时的反向浪涌与损耗,支持50kHz以上的开关频率。

4. 温度特性

  • 工作结温范围:-55℃~+150℃,符合工业级标准,可适应户外(如太阳能逆变器)、车载等温度波动大的场景;
  • 参数稳定性:Vf随温度升高略有增加(约0.1%/℃),Trr随温度升高略有延长,但150℃时仍保持在100ns以内,不影响高频性能。

三、封装与可靠性设计

ES2J采用SMB(DO-214AA)表面贴装封装,尺寸为2.4mm×3.2mm×1.6mm,具有以下优势:

  • 小型化:适合高密度PCB设计,减少设备体积;
  • 焊接可靠性:引脚采用镀锡工艺,兼容回流焊、波峰焊,焊接强度符合IPC标准;
  • 环保合规:符合RoHS 2.0与REACH标准,无铅无卤,满足欧盟市场要求;
  • 热设计:封装内部采用低热阻结构(结到壳热阻Rth(jc)≈15℃/W),配合PCB铜箔散热,可有效控制结温。

四、选型与替换注意事项

  1. 参数匹配原则:替换时需满足「Vr≥600V、If≥2A、Trr≤35ns、封装SMB」,同规格替代型号包括US2J(安森美)、RS2J(罗姆)等;
  2. 散热设计:实际应用中需控制结温在125℃以下(安全余量),建议在SMB封装引脚处增加10mm²以上铜箔,或配合小型散热片;
  3. 避免过应力:反向电压需低于600V(峰值),连续电流不超过2A,脉冲电流需控制在规格书范围内。

五、总结

ES2J作为台冠电子的中小功率超快恢复二极管,以低损耗、快恢复、宽温范围为核心优势,适配高频开关电路的效率与可靠性需求,SMB封装适合小型化设备设计,是开关电源、LED驱动等场景的高性价比选择。

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
