ES1D (SMA) 产品概述

ES1D 是 DOWO(东沃)推出的一款通用快速恢复整流二极管,SMA 封装,额定整流电流 1A、反向耐压 200V。凭借低正向压降、较小反向漏电和快速恢复特性,适用于开关电源、整流、反向保护及浪涌钳位等多种电路场合。

一、主要参数

  • 型号:ES1D(SMA)
  • 品牌:DOWO(东沃)
  • 封装:SMA(表面贴装)
  • 额定整流电流:1A(连续)
  • 直流反向耐压 Vr:200V
  • 正向压降 Vf:1.3V @ 1A
  • 反向电流 Ir:5 μA(常温)
  • 反向恢复时间 Trr:35 ns
  • 结温工作范围:-55 ℃ ~ +150 ℃

二、产品特点

  • 低正向压降:1.3V(1A)有助于降低整流损耗,提高效率,适合中小功率应用。
  • 低反向泄漏:5 μA(常温)在高阻抗或待机电路中能有效控制漏电导致的功耗与误动作。
  • 快速恢复:Trr ≈ 35 ns,响应快,适合频率较高的开关电源和脉冲应用(注意非超快恢复类别)。
  • 宽温度范围:结温 -55~150 ℃,可靠性高,适应工业环境。

三、典型应用

  • 开关电源(整流/续流二极管)
  • 单相桥式整流电路
  • 电池充放电保护与反向保护
  • 输入浪涌和过压钳位
  • 家电、照明驱动及工业控制模块

四、封装与装配建议

SMA 表面贴装封装,便于自动贴片和回流焊装配。推荐遵循制造商提供的回流温度曲线,避免长时间高温回流以保护结温和引线连接。PCB 布局时注意散热路径:在二极管引脚附近增加铜箔或散热过孔,有助于提升长期电流承载能力。

五、使用与可靠性注意事项

  • 连续工作电流接近额定值时应考虑散热条件与环境温度,必要时降额使用以延长寿命。
  • 在高频高应力场合,若对反向恢复时间和电磁干扰有更严格要求,可考虑超快恢复或肖特基方案。
  • 存储时避免潮湿,封装开封后按 SMD 焊接规范处理以防潮。

六、选型建议

ES1D 适合追求性价比的通用整流场景;若需更低 Vf(如对效率极为敏感)或更短 Trr(高频开关、更低 EMI),可比较肖特基二极管或超快恢复型号。购买和备货时请核对封装(SMA)、电压等级和实测 Vf 曲线以符合实际应用需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
