ES2D 产品概述
一、产品简介
ES2D 是江苏长电（CJ/长晶）推出的一款独立式快恢复、高效率整流二极管（封装：SMAG）。该器件在2A工作电流下正向压降典型为0.95V，直流反向耐压200V，反向电流仅5µA（Vr=200V），反向恢复时间Trr约35ns，非重复峰值浪涌电流Ifsm可达50A，结温工作范围宽（Tj = -55℃ ~ +150℃）。总体定位为中功率开关电源与整流场合的高效率快恢复二极管。
二、主要参数要点
- 封装：SMAG（SMA 型玻封/玻封类似封装，便于波峰/回流焊接与自动贴装）。
- 正向压降 Vf：0.95V @ If = 2A（低 Vf 有利于降低导通损耗）。
- 额定整流电流 If(AV)：2A。
- 反向耐压 Vr：200V（适用于中高压整流与开关电源次级整流）。
- 反向电流 Ir：5µA @ 200V（低漏电，有利于提高待机效率）。
- 反向恢复时间 Trr：35ns（属于快恢复类型，适配高频开关，但非超快恢复或肖特基级别）。
- 峰值浪涌 Ifsm：50A（短时冲击吸收能力良好）。
- 工作结温：-55℃ ~ +150℃。
三、性能优势与设计意义
- 低正向压降（0.95V）直接降低导通损耗：在2A连续工作时器件自身耗散约1.9W（Pd≈Vf×If），需按实际散热条件计算并做好热设计。
- 35ns 的快恢复特性在典型SMPS二极管整流、反并联回收或钳位回路中，可有效减少反向恢复引起的开关损耗与电磁干扰（EMI）。
- 低漏电流与宽工作温区提升系统待机效率与可靠性，适合消费类电源、适配器和LED驱动等应用。
四、典型应用场景
- 开关电源（SMPS）次级整流或整流桥替代件。
- AC/DC 适配器、电池充电器、LED 驱动电源。
- 电机驱动与逆变器的自由轮回路（中频场合）。
- PFC 折返、钳位/吸收电路以及一般功率整流。
五、使用与布局建议
- 热管理：连续2A条件下需关注器件导热至焊盘与PCB，建议增大铜箔面积或加散热铜箔/散热片以保证结温在安全范围内。
- 冲击与浪涌：若应用场合存在频繁或高能量浪涌，应评估Ifsm与浪涌持续时间，并配合熔断/限流元件保护。
- 并联注意：不建议直接并联多只二极管以提高电流，因正向压降存在差异；若必须并联，应加均流电阻或采用专用并联方案。
- 开关噪声：在高dv/dt或高速开关中，考虑配合RCD钳位或RC缓冲网络以抑制尖峰与降低EMI。
六、封装与采购提示
- 型号识别可标注为 CJ ES2D-SMAG（具体管脚与标记以厂家资料为准）。
- 量产选型时建议索取器件完整数据手册、典型曲线（Vf-T、Ir-T、Trr波形）及可靠性报告，以便进行热仿真与寿命评估。
总结：ES2D 以低正向压降、适中快恢复时间和较低漏电流，在SMAG封装中为中功率、高效率整流场合提供一个性价比较高的选择。设计时重点关注散热和开关浪涌管理，以充分发挥其快恢复与低损耗优势。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
