ES1JA 产品概述 — DOWO(东沃)

一、产品简介

ES1JA 是 DOWO(东沃)推出的一款高压超快恢复整流二极管,单片封装为 SMA,属独立式元件。器件采用玻璃钝化结芯片,具有超快恢复时间和高效率特性,内置应力消除结构,适合自动贴装生产,符合 RoHS 标准且无卤素。

二、主要电气参数

  • 正向压降 (Vf):典型 1.7V @ 1A
  • 直流反向耐压 (Vr):600V
  • 整流电流:1A(平均整流电流)
  • 反向电流 (Ir):5µA(典型/最大值阶)
  • 反向恢复时间 (Trr):35ns(超快恢复)
  • 工作结温范围:-55℃ ~ +150℃

三、关键特性

  • 玻璃钝化结芯片,提升可靠性与抗湿热性能;
  • 超快恢复(Trr≈35ns),在开关电源和高频整流场景中可显著降低开关损耗与电磁干扰;
  • 低反向漏电(Ir≈5µA),适用于高压低漏电要求的电路;
  • 内置应力消除设计,提高焊接和热循环下的机械可靠性;
  • SMA 封装,适合自动贴片(SMT)工艺,节省 PCB 空间;
  • 符合 RoHS 与无卤标准,利于环保与法规合规。

四、典型应用场景

  • 开关电源(SMPS)输出整流与续流;
  • 反激/正激变换器的续流或回收整流;
  • 功率因数校正电路(PFC)与高压整流应用;
  • 太阳能逆变器、适配器、充电器等高压开关场合;
  • 需要高频率开关兼顾高压耐受与低反向漏电的工业及消费电子设备。

五、封装与可靠性

SMA 小型封装便于自动贴装与波峰/回流焊接。玻璃钝化工艺与应力消除结构提高了焊接热循环、振动及长期运行的可靠性。工作结温可达 +150℃,适应宽温度工况。

六、选型与使用建议

  • 当应用电压接近或不超过 600V 且工作电流在 1A 范围内时,ES1JA 为优选整流器件;
  • 高频开关电源中,超快恢复性能有助于减少功耗与 EMI,应配合合适的缓冲与屏蔽设计;
  • 设计时预留足够散热路径与铜箔面积以控制结温;焊接工艺按厂家推荐回流曲线执行以避免热应力损伤。

ES1JA 凭借高压耐受、超快恢复与小型封装,是需要高频、高压整流与可靠焊接的电子产品的理想选择。若需完整数据手册(包括典型波形、热阻、最大脉冲电流等参数),建议联系 DOWO 或查询官方技术资料以获得详尽规格与应用注意事项。

Electronic component sourcing availability dashboard with ESD-protected samples

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
