ES2JA 产品概述
一、产品简介
ES2JA 是 FUXINSEMI（富芯森美）推出的独立式快恢复/高效率二极管，封装为 SMA (DO-214AC)。额定直流整流电流 2A，最高反向耐压 600V，正向压降典型值 Vf = 1.7V（@2A），反向电流 Ir ≈ 6µA，反向恢复时间 Trr = 35ns，非重复峰值浪涌电流 Ifsm = 50A，工作结温范围 -55℃ ～ +150℃。该器件面向开关电源和高压整流场合，兼顾低损耗与快速恢复性能。
二、主要特性
- 600V 高反向耐压，适用于离线大电压场景。
- Vf 1.7V@2A，导通损耗较低，有利于提高效率。
- 快恢复时间 35ns，减少开关损耗与复位相关能量。
- 低静态漏电 6µA（典型），利于高阻断电压下的低功耗设计。
- SMA 小封装，适配紧凑 PCB 布局；Ifsm 50A 能承受启动/浪涌脉冲。
三、典型应用
- 开关电源（SMPS）输出整流与续流二极管
- 离线适配器、LED 驱动电源、功率因数校正（PFC）电路
- 电池充电器、工业电源、逆变器／驱动电路的高压整流与保护
- 作为快速恢复或高效率替代的一般整流元件
四、设计与使用要点
- Vf×If 在持续导通时会产生显著功耗（例：1.7V×2A≈3.4W），在 SMA 封装下需通过加大铜箔和散热铺铜来管理结温，必要时考虑并联或选择更大封装。
- 快恢复特性有助于降低开关损耗，但在高速开关时仍可能引起 EMI，建议与 RC 缓冲/吸收电路或适当的放电网络配合使用。
- 布局上应缩短高电流回路的走线、减小环路面积，SMA 焊盘应按厂商推荐过孔和铜箔面积设计以利散热。
- 考虑环境温度与长期可靠性时，应按厂商数据手册进行温升与降额设计。
五、封装与可靠性
SMA (DO-214AC) 封装体积小、便于自动贴装和回流焊接，适合批量生产与紧凑设计。工作结温范围宽（-55℃ 至 +150℃），强调在合理散热条件下可稳定工作。非重复峰值浪涌电流 50A 能应对短时浪涌，但不宜作为长期过载手段。
六、选型建议
在要求长期 2A 输出且散热条件受限的应用，应评估热阻并考虑更大封装或并联器件；对 EMI 敏感的系统，应验证 35ns 的恢复行为是否满足系统 EMC 要求并做适当抑制。更多电气特性、热阻曲线和封装尺寸请参阅厂家数据手册或联系 FUXINSEMI 技术支持获取详细资料和参考封装库。

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.
