ES3J是江苏长电(CJ)推出的独立式快恢复/高效率二极管,针对中小功率高频整流、续流场景优化设计,具备低正向压降、快速反向恢复、宽温适应等核心优势,广泛应用于电源、LED驱动、逆变器等领域。
ES3J属于快恢复二极管(FRD)范畴,兼具高效率特性——区别于普通整流二极管的慢恢复特性,其35ns反向恢复时间可显著降低高频开关损耗,提升电路效率。作为单管独立式设计,无需并联/串联即可满足3A持续整流需求,适配中小功率系统的紧凑布局要求。
ES3J的参数平衡了功率容量与开关性能,核心参数如下:
ES3J采用SMBG封装(表面贴装型玻璃钝化封装),具备以下特点:
ES3J的参数特性适配多类中小功率高频电路:
ES3J由江苏长电(CJ)生产,长电作为国内半导体龙头,具备完善品质管控:
总结:ES3J以3A/600V、35ns恢复时间为核心优势,结合SMBG封装的紧凑性与长电可靠性,是电源、LED驱动等领域的高性价比选型。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
