ES1J 产品概述
一、产品简介
ES1J 为 DIOTEC（德欧泰克）出品的 Superfast 整流二极管，封装为 SMA（DO-214AC），面向开关电源、功率整流及高速开关保护等应用。该器件在 600V 反向耐压下能提供 1A 连续整流电流，具备较低的正向压降与较快的反向恢复特性，适合中功率、高频率整流场合。
二、主要性能参数
- 工作结温范围：-50℃ ~ +150℃
- 正向压降 Vf：1.7V @ 1A
- 直流反向耐压 Vr：600V
- 反向电流 Ir：5 μA（在额定条件）
- 反向恢复时间 Trr：35 ns
- 连续整流电流：1 A
- 封装：SMA (DO-214AC)
三、特性与优势
- 高耐压：600V 额定可满足大多数中高压整流与阻断要求。
- 超快恢复：Trr 约 35ns，能有效减少开关损耗与反向恢复引起的额外损耗，适用于中频率开关电源与高频整流。
- 稳定的正向表现：1A 工作点下 ~1.7V 的正向压降，在中等功率范围内兼顾损耗与热量控制。
- 宽温区可靠性：-50℃ 到 +150℃ 的结温范围支持工业级环境与高温运行场景。
四、典型应用场景
- 开关电源（SMPS）整流与续流二极管
- 电机驱动与功率电子中的自由轮二极管
- 充电设备与整流桥（需并联或选型注意电流分配）
- 逆变器与太阳能逆变器辅助整流
- 保护电路（反接保护、肖特基替代场合视损耗要求）
五、设计与布局注意事项
- 反向恢复导致的浪涌和振铃：尽管 Trr 较快，快速开关中仍可能产生电压尖峰和 EMI，建议根据系统开关速度配合 RC 缓冲或 TVS 限压器。
- 热设计：Vf 导致的功耗 P ≈ Vf × IF，在 1A 连续工作时约 1.7W，需评估 PCB 散热路径与封装热阻，必要时在布局处增加铜箔面积或采用散热器。
- 并联使用：若需提升电流，应确保每只二极管的分流一致，可采用小电阻平衡或热耦合设计，避免单只过流。
- 焊接与装配：SMA 封装适配回流与波峰焊，请遵循制造商推荐的焊接工艺以防损伤，避免过热造成性能下降。
六、可靠性与选型提示
- 在高频、高 dv/dt 场合，评估反向恢复引起的额外损耗与电磁干扰，必要时考虑采用更低 Trr 或软恢复特性的器件。
- 若运行电流长期接近 1A，应进行适当的功率与温升余量设计，确保结温不超过 150℃。
- 对于要求极低正向压降的应用（如极高效率电源），可对比肖特基二极管或更低 Vf 的器件；对极低反向恢复要求的应用，则考虑超快速或无恢复（soft-recovery）器件。
总结：ES1J（DIOTEC，SMA 封装）为一款在中高压、1A 级别应用中兼顾速度与耐压的 Superfast 整流二极管，适合多数工业级开关与整流场合。合理的热管理与布线配合能发挥其性能优势并保证长期可靠性。

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.
