ES3GB 是扬杰(YANGJIE)推出的一款独立式快恢复/高效率二极管,封装为 SMB。该器件为 3A 额定整流电流、400V 反向耐压的整流二极管,典型正向压降为 1.3V(在 3A 时),反向恢复时间 Trr 约 35ns,适用于开关电源、电源适配器、功率因数校正(PFC)、逆变器及马达驱动等需要较低开关损耗与快速恢复特性的场合。
这些参数表明 ES3GB 在中等电流与中高压应用中能提供较低的导通压降与较快的恢复速度,从而降低导通与开关损耗,提升系统效率。
SMB 封装使器件具有中等散热能力,实际使用中应注意PCB散热设计:
适用场景包括开关电源整流、续流二极管、PFC 电路、逆变输出整流、LED 驱动器等。设计时需注意:
ES3GB 适合追求中等电流、高效率与快速开关性能的设计。若需更低正向压降或更高电流能力,可考虑更大封装或肖特基二极管(但需权衡反向耐压与漏电流);若系统对反向恢复特性要求极高,可查询更短 Trr 或专用快恢复系列。选型时优先确认最大工作电压、峰值浪涌电流及热设计余量。
总结:ES3GB 以 400V/3A 的电气规格、1.3V 的低正向压降与 35ns 的快速恢复特性,在中高压开关电源与整流场景中提供可靠的高效率整流解决方案。

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.
