ES3G —— 快恢复/高效率独立二极管产品概述
一、产品简介
ES3G 是扬杰（YANGJIE）品牌的一款独立式快恢复二极管，封装为 SMC，面向中功率开关电源与整流应用。其主要电气参数包括：正向压降 Vf = 1.3V @ 3A、直流反向耐压 Vr = 400V、整流电流 IF(AV) = 3A、反向电流 Ir = 5 μA @ 400V、反向恢复时间 Trr = 35 ns、非重复峰值浪涌电流 Ifsm = 100A，工作结温范围 Tj = -55℃ ~ +150℃。该器件兼顾低导通损耗与快速恢复特性，适合提高系统效率并降低电磁干扰。
二、主要特性
- 低正向压降：1.3V @ 3A，减少导通损耗，适合长时间整流应用。
- 快恢复速度：Trr = 35 ns，有利于降低开关过渡期的反向恢复峰值电流和功率损耗。
- 高反向耐压：Vr = 400V，可满足多数离线开关电源与适配器的电压要求。
- 低漏泄电流：Ir = 5 μA @ 400V，利于空载能耗控制与高温下的可靠性表现。
- 良好浪涌承受力：Ifsm = 100A，增强对启动或短时过流冲击的鲁棒性。
- 宽工作温度：Tj 可达 +150℃，适应高温工作环境。
三、典型应用场景
- 开关电源（SMPS）输出整流与整流桥。
- 离线适配器、充电器的整流与续流保护。
- DC-DC 转换器中的二极管整流/续流。
- 家电与照明电源中的高压整流场合。
- 需要抗浪涌和低漏泄的工业电源。
四、使用与热设计要点
- 持续整流电流为 3A，长期工作时应关注封装的散热路径，建议使用较宽的 PCB 散热铜箔或外加散热片。
- 在高频开关环境中，尽管 Trr = 35 ns 已属快恢复，但仍需优化布局以降低寄生电感，减小反向恢复产生的电压尖峰。
- 在并联使用以提高电流能力时，应注意正向压降匹配与热均衡，推荐在相同 PCB 环境下严格器件一致性控制。
- 工作温度接近上限时应考虑降容使用或加强散热以延长寿命并降低漏电。
五、选型与可靠性建议
- 若系统开关频率较高或对 EMI 要求严格，可优先选用更短 Trr 或肖特基器件；但 ES3G 在效率与耐压间提供了良好平衡，适合多数 400V 级别应用。
- 关注数据表中额定值与热阻参数（请参阅扬杰正式资料），在不清晰时进行实测验证。
- 存储与焊接遵循常规无铅工艺温度曲线，避免长期在高湿高温环境下保存，以防性能劣化。
总结：ES3G（SMC 封装）是一款面向中功率整流与续流用途的快恢复二极管，凭借 400V 耐压、1.3V@3A 的低压降、35ns 的恢复时间和 100A 的浪涌能力，为开关电源与工控电源提供了可靠且高效的整流解决方案。选择与设计时请结合具体电路频率、散热条件与浪涌要求进行综合评估。

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.
