ES2JB 产品概述
一、产品简介
ES2JB 是 FOSAN（富信）推出的一款快恢复、高效率整流二极管，SMB 表面贴装封装，面向中高压开关电源与电力电子应用。器件兼顾低正向压降与快速反向恢复，适合对效率与开关性能有要求的场合。
二、主要参数
- 正向压降 (Vf)：1.7V @ IF=2A
- 直流反向耐压 (Vr)：600V
- 最大整流电流：2A
- 反向电流 (Ir)：5μA @ 600V
- 反向恢复时间 (Trr)：35ns
- 工作结温：-65℃ ~ +150℃
- 封装：SMB（DO-214AA）
三、关键特性
- 低正向压降（1.7V@2A）：在高电流工况下降低导通损耗，有助于提高整机效率并减少散热需求。
- 快恢复（Trr≈35ns）：在开关频率较高的电源中可显著减少开关损耗与电磁干扰（EMI）。
- 高耐压与低漏电：600V 反压等级配合 5μA 的低反向电流，适用于高压整流与续流场合。
- 宽温度范围：-65℃~150℃ 的工作结温提高了在恶劣环境下的可靠性与寿命。
四、典型应用
- 开关电源（SMPS）输出整流或续流二极管
- 电池充电器、LED 驱动器与适配器
- 功率因数校正（PFC）电路的整流件
- 电机驱动、逆变器与离线电源的高压整流场景
五、封装与可靠性
SMB 封装支持波峰/回流焊工艺，具有良好热性能与稳固的焊接强度，便于自动化贴装与批量生产。器件工作结温范围宽，适合长期可靠运行；建议按厂商回流曲线焊接并在设计中预留合适的散热路径。
六、使用建议
- 在高频开关电路中注意与缓冲网络（RC、吸收器）配合，以降低尖峰电压。
- 如需并联器件以增加电流能力，应选配匹配器件并考虑均流措施。
- PCB 布局上尽量缩短高电流回路走线并增大焊盘/铜面积以利散热。
- 订购型号：ES2JB，品牌：FOSAN（富信）。
总体而言，ES2JB 以其 600V 耐压、快恢复特性和低漏电优势，适合对效率和开关性能有较高要求的中高压功率应用。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
