ES3GB 产品概述

一、产品简介

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。

二、主要电气参数

  • 二极管配置:独立式(非共阴或共阳组合封装)
  • 正向压降(Vf):1.3V @ If = 3A
  • 直流反向耐压(Vr):400V
  • 额定整流电流:3A(Io)
  • 反向漏电流(Ir):10µA @ Vr = 400V
  • 反向恢复时间(Trr):35ns(典型)
  • 工作结温范围(Tj):-55℃ 至 +150℃

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。

三、主要优点与特性

  • 低正向压降:在 3A 工作点时 Vf 约 1.3V,可显著降低导通损耗与发热。
  • 快速恢复:Trr ≈ 35ns,有利于缩短开关瞬态时间,减少开关能量损耗与 EMI 产生。
  • 低漏电流:在 400V 反向时仅 10µA,适合高压直流侧整流应用。
  • 宽工作温度:-55℃ 至 +150℃ 的结温范围,适应工业级温度要求。
  • SMB 封装:便于手工与自动贴装,兼顾散热与机械强度。

四、封装与散热建议

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:

  • 在二极管下方与引脚附近增加铜箔面积以降低结-壳-板热阻;
  • 必要时在焊盘下布置热通孔(thermal vias)将热量引到多层板内或背面散热层;
  • 保证良好的焊接热接触和合理的回流工艺以避免焊点虚焊。

五、应用场景与设计注意事项

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:

  • 反向恢复虽然快,但在高 dv/dt 条件下仍会产生瞬态电流,必要时并联缓冲或采用 RC 吸收网络减少峰值应力;
  • 在高温或长时间大电流工作时应考虑额定电流的热降额(derating);
  • 并联多只二极管以提高电流能力时需注意电流共享问题,建议并联前进行匹配或加限流措施;
  • PCB 布局应尽量缩短信号与电流回路环路面积以降低 EMI。

六、选型建议与替代参考

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。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
