ES2JA 产品概述
一、产品简介
ES2JA 是扬杰（YANGJIE）推出的一款快恢复、高效能独立式整流二极管，封装为 SMA。该器件在高压环境下具备良好的开关性能与较低的漏电，典型应用于电源整流、开关电源钳位、续流及功率转换电路。
■ 主要参数一览：
- 正向压降 Vf = 1.7V @ IF = 2A
- 直流反向耐压 Vr = 600V
- 最大整流电流 IF(AV) = 2A
- 反向电流 Ir = 5 μA @ 600V
- 反向恢复时间 Trr = 35 ns
- 工作结温范围 Tj = -55℃ ~ +150℃
二、核心特性
- 快恢复特性：Trr 约 35ns，相比传统慢恢复整流器降低开关损耗与电磁干扰，适合中高频开关电源。
- 高耐压：600V 额定，可用于高压整流、反向保护及高压开关场合。
- 低反向漏电：在 600V 时 Ir 仅 5μA，有利于高压低功耗系统稳定性。
- 紧凑封装：SMA 体积小，便于表面贴装生产与热管理方案的优化。
三、推荐应用场景
- 开关电源（SMPS）输出整流与钳位
- 功率因数校正（PFC）二极管与续流路径
- 适配器、LED 驱动、电视与显示器电源
- 电机驱动与逆变器中高压整流与保护
四、热管理与使用建议
- 额定 2A 为器件热极限下的整流能力，实际使用中应根据 PCB 散热能力和环境温度进行降额设计；高环境温度下建议降低工作电流以保证结温不超过 150℃。
- SMA 封装热阻相对较高，推荐在铜箔较大、散热良好的 PCB 区域焊接，并可并联多只或配合散热片使用以提升连续功率处理能力。
- 焊接时遵循器件制造商的回流曲线，避免长时间过高温度以防破坏封装或内部结构。
五、典型电路与注意事项
- 在桥式整流、续流二极管等场合，注意开关瞬态电压和反向恢复导致的浪涌电流；必要时串联限流或在并联电阻/RC 吸收回路来抑制尖峰。
- 反向恢复特征（35ns）虽属快恢复范畴，但在超高频或高 dv/dt 场合可能产生较大反向恢复电流，应评估对开关器件（如 MOSFET）的冲击并采取缓冲措施。
- 在高压电路中注意爬电距离与绝缘，避免表面污染导致泄漏或闪络。
六、选型对比与替代建议
与低压肖特基二极管相比，ES2JA 的 Vf 较高（1.7V @2A），但提供了更高的反向耐压（600V）和更低的反向漏电，适合高压整流场合；若需更低正向压降可考虑低压大电流肖特基，但耐压通常受限。若需更快恢复时间（<20ns），可选超快恢复系列，但可能在反向漏电或成本上有权衡。
七、结语
ES2JA 在高压快恢复整流应用中体现出良好的性价比与可靠性。设计时应关注散热与反向恢复引起的瞬态问题，通过合理的 PCB 布局与电路抑制措施，可获得稳定的长期运行表现。若需详细封装图、热阻或回流规范，建议参考扬杰官方数据手册。

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.
