ES2G 快恢复/高效率二极管 — 产品概述
一、产品概述
ES2G 是扬杰（YANGJIE）推出的一款独立式快恢复/高效率整流二极管，采用 SMB（DO-214AA）封装，面向开关电源、适配器、逆变器及各种中高压整流场合。器件在 2A 连续整流条件下具有低正向压降与较短的反向恢复时间，可在提高转换效率的同时抑制开关损耗与杂散电磁干扰。
二、主要特性
- 独立式封装：SMB（DO-214AA），便于贴装与散热处理。
- 正向压降：Vf = 1.3V @ If = 2A，体现出较低的导通损耗。
- 额定整流电流：2A（连续）。
- 非重复峰值浪涌电流：Ifsm = 50A，具备良好的浪涌承受能力。
- 直流反向耐压：Vr = 400V，适用于中高压整流。
- 反向漏电流：Ir = 5μA @ 400V，漏电小，有利于降低静态损耗。
- 反向恢复时间：Trr = 35ns，开关过程中恢复较快，减少能量回收与 EMI。
三、电气与温度范围
- 工作结温范围：Tj = -55℃ ~ +150℃，（器件允许的极限结温）。
- 在实际应用中应按温度－电流降额曲线考虑长期可靠性与散热设计，避免在高结温下长期满载运行。
四、典型应用场景
- 开关电源（SMPS）的输出与回收整流。
- 电源适配器、充电器、LED 驱动电源。
- 电机驱动与逆变器的自由轮回路（中低频至中高频）。
- 工业电源、电视与显示电源的整流/稳压环节。
五、设计与使用建议
- 对于高频开关应用，Trr=35ns 表现为“快恢复”级别，能显著降低开关损耗，但仍建议配合适当的缓冲网络（RC 或 RCD 回路）来抑制尖峰与振铃。
- 布局时应尽量减小二极管与开关器件间的回流回路面积，增加散热铜箔面积以降低结壳温升。
- 连续电流 2A 为器件额定值，实际设计中需根据工作温度进行降额使用，并参考完整数据手册中的热阻与降额曲线。
- 浪涌能力 Ifsm=50A 表示器件对瞬态冲击有良好承受力，但长期反复浪涌仍会影响可靠性，应在必要时加装限流或软启动。
六、封装与可靠性注意事项
- SMB（DO-214AA）封装适合手工与波峰/回流焊装配，焊接时应遵循制造商的温度曲线与时长限制，避免超温导致性能退化。
- 储存与使用环境应避免潮湿与腐蚀性气氛，必要时按湿度敏感器件（MSD）处理。
- 建议在设计评估阶段进行热仿真与实测，以验证在目标工况下的结温和寿命预估。
总结：ES2G 以其 400V 耐压、1.3V@2A 的低压降、50A 浪涌能力及 35ns 的快恢复特性，适合用于各类中高压整流与中高频开关电源场合，是兼顾效率与可靠性的实用整流选择。购买与详细参数请以扬杰官方数据手册为准。

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.
