ES2GA 产品概述

一、产品简介

ES2GA 为 YANGJIE(扬杰)推出的一款独立式快恢复/高效率整流二极管,封装为 SMA(表面贴装)。器件在 2A 工作电流下正向压降仅为 1.3V,反向耐压达到 400V,同时具备短反向恢复时间(Trr = 35ns)和低反向泄漏电流(Ir = 5µA@400V)。广泛适用于开关电源、适配器、充电器以及各种需要高压整流与快速恢复性能的电路。

二、主要参数

  • 器件类型:独立式(Discrete)二极管
  • 正向压降(Vf):1.3V @ IF = 2A
  • 直流反向耐压(Vr):400V
  • 额定整流电流:2A(DC)
  • 反向电流(Ir):5µA @ VR = 400V
  • 反向恢复时间(Trr):35ns
  • 工作结温范围:-55℃ ~ +150℃(Tj)
  • 封装形式:SMA(表面贴装)

三、主要特性与优势

  • 高耐压:400V 反向耐压适配市电整流和中高压开关电源设计,能够承受较大的脉冲与反向应力。
  • 低正向压降:在 2A 条件下 Vf = 1.3V,有助于降低整流损耗,提高整体转换效率。
  • 快恢复特性:Trr = 35ns,比普通整流二极管恢复快,减少反向恢复电流对开关器件和电路的干扰,适合中高频开关场合。
  • 低漏电流:在高压下反向漏电小(5µA@400V),利于降低待机功耗和系统静态损耗。
  • 宽温度适应性:-55℃ 至 +150℃ 的结温范围保证在苛刻环境下仍具可靠性。

四、典型应用场景

  • 开关电源(SMPS)次级整流与原边回灌回路
  • 交流-直流适配器、手机/笔记本充电器整流
  • 电机驱动与逆变器的续流/钳位保护
  • 功率因数校正(PFC)电路中的整流与保护
  • 工控、电源模块及一般高压整流场景

五、使用与选型建议

  • 频率与恢复特性:ES2GA 的 Trr = 35ns 适合中高频开关电源(几百 kHz 以下或相近频段)。若系统工作在更高频率或要求更小开关损耗,可考虑超快恢复或肖特基二极管作为替代,注意肖特基器件在高压下的耐压限制。
  • 散热与封装:SMA 为表面贴装封装,散热能力有限。2A 连续整流时需在 PCB 设计上增大散热铜箔面积和通过孔,避免长期高结温导致性能退化。
  • 环境与可靠性:在高温或高湿环境下使用时,建议进行热仿真与寿命评估,并留意器件的结温升高对正向压降与漏电的影响。
  • 波峰电流与浪涌:若电路可能出现较大的浪涌电流或瞬态冲击,请参考完整数据手册中的峰值整流电流和浪涌能力参数,必要时并联或选用更高额定电流的器件。

六、包装与焊接注意

  • 封装为 SMA(表面贴装),适配标准 SMT 贴片工艺。
  • 焊接建议参考厂商提供的回流曲线与焊接工艺规程,以避免因温度超限导致的器件应力或性能变化。
  • 储存与防潮:建议按电子元件一般防潮要求保存,必要时在贴片前进行回流前的烘烤处理。

总结:ES2GA 以其 400V 的高耐压、2A 的整流能力、较低的正向压降和快速恢复特性,在需要兼顾效率与可靠性的中高压整流应用中具有良好性价比。具体设计应结合系统频率、散热条件以及浪涌要求,参考完整 datasheet 作最终选型与布局。

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
