ES3JBG 产品概述
一、产品简介
ES3JBG 是 SHIKUES（时科）推出的一款独立式快恢复、高效率整流二极管，封装为 SMB。凭借低正向压降与较短的反向恢复时间，适用于开关电源、整流和浪涌吸收等中高压功率场合。器件设计兼顾电流承载与热稳定性，适配工业级温度范围。
二、主要电气参数
- 二极管配置：独立式（Discrete）
- 正向压降（Vf）：1.68 V @ IF = 3 A
- 直流整流电流：3 A
- 直流反向耐压（Vr）：600 V
- 反向电流（Ir）：5 μA @ Vr = 600 V
- 反向恢复时间（Trr）：35 ns
- 结温工作范围（Tj）：-55 ℃ ~ +150 ℃
- 封装：SMB
三、主要特性与优势
- 低正向压降：1.68 V@3 A 有助于降低导通损耗，提高整机效率。
- 快恢复特性：35 ns 的反向恢复时间减小开关损耗与电磁干扰（EMI），适合中高速开关电路。
- 高耐压能力：600 V 的反向耐压适合大多数中高压开关电源与整流场景。
- 宽温度范围：-55 ℃ 至 150 ℃ 满足工业级环境工作要求。
- 低反向漏电：5 μA 在高压下保持较低漏电，利于提高系统待机效率。
四、典型应用场景
- 开关电源（SMPS）输出整流与续流回路
- 电池充电器与适配器整流部分
- 逆变器与太阳能光伏发电系统的整流/自由轮回路
- 电机驱动的再生制动与吸收电路
- 工业电源、LED 驱动与电源滤波回路
五、封装与散热建议
SMB 封装适合自动化贴装与手工焊接。在高功率工作点应注意散热设计：
- 保持良好PCB铜箔面积以增大散热面积；
- 若长时间大电流工作，建议加热沉或增强散热路径；
- 注意焊接工艺，避免过热影响结温。
六、设计与使用注意事项
- 工作电压不应超过额定 Vr（600 V），并考虑浪涌与瞬态过压的裕量；
- 在高频开关场合需评估反向恢复带来的电压尖峰，必要时配合软恢复或阻尼网络；
- 根据实际环境对结温进行降额设计，确保长期可靠性。
七、选型与采购建议
在选型时，结合负载电流、开关频率及系统耐压需求评估 ES3JBG 是否满足要求。需要更高浪涌能力或更低正向压降时，可联系供应商获取完整数据表及样品。SHIKUES（时科）品牌提供的独立器件适合需要可替换性与维修性的工业应用。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
