ES3JB是台冠电子(TDD)推出的1个独立式超快恢复整流二极管,采用SMB(DO-214AA)表面贴装封装,属于中功率高压快恢复器件范畴。该产品针对高频开关电源、逆变器等需要快速反向恢复的场景优化,兼具高耐压、低损耗、宽温适应性等特点,是小型化、高效率电子设备的理想整流/续流元件。
ES3JB的核心参数围绕“高频、高压、低损耗”设计,具体解析如下:
ES3JB采用SMB(DO-214AA)表面贴装封装,具体物理特性(参考行业标准):
小尺寸封装节省PCB空间(比TO-220封装节省约80%面积),适合手机充电器、LED驱动电源等小型化产品,同时便于批量生产,降低组装成本(贴装成本比直插封装低约30%)。
ES3JB的参数匹配多类高频、中功率电子设备,典型应用包括:
相比同类产品(如FR307、ES3A),ES3JB的核心优势在于:
该产品适合电源制造商、家电厂商、工业控制设备厂家等客户,可直接替换FR307、ES3A等快恢复二极管,提升产品性能的同时控制成本。
台冠电子作为国内二极管领域的专业厂商,ES3JB通过了高温老化(150℃×1000小时)、温度循环(-55℃~150℃×500次)等可靠性测试,确保批量产品一致性,是值得信赖的中功率快恢复解决方案。

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.
