ER304_AY_10001 产品概述

一、产品简介

ER304_AY_10001 为 PANJIT(强茂)出品的一款独立式快恢复/高效率整流二极管,采用 DO-201AD 轴向封装。器件针对中功率开关和整流应用设计,具备低正向压降与快速反向恢复特性,可在高频切换场合有效降低导通与开关损耗,提升系统效率与可靠性。

二、主要参数一览

  • 二极管类型:独立式、快恢复/高效率整流二极管
  • 正向压降 (Vf):1.25V @ If = 3A
  • 直流反向耐压 (Vr):400V
  • 额定整流电流:3A(持续)
  • 反向电流 (Ir):1µA @ Vr = 400V
  • 反向恢复时间 (Trr):35ns(典型)
  • 非重复峰值浪涌电流 (Ifsm):125A
  • 工作结温:-55℃ ~ +150℃
  • 封装:DO-201AD(轴向)
  • 品牌:PANJIT(强茂)

三、性能亮点

  • 低正向压降(1.25V@3A)降低导通损耗,适合整流与功率传输场景。
  • 快速反向恢复(Trr≈35ns)减小开关损耗与反向恢复电流,抑制开关时产生的浪涌与电磁干扰。
  • 低反向漏电(1µA@400V)有利于高阻断电压时维持低损耗与高稳定性。
  • 高浪涌承受能力(Ifsm=125A)适用于开机冲击与瞬态过电流情况,提升抗冲击能力。
  • 宽工作结温范围(-55℃~+150℃),适应工业级和恶劣环境使用。

四、典型应用场景

  • 开关电源(SMPS)中的输出整流或中间总线整流
  • 功率因数校正(PFC)电路及前端整流
  • 逆变器和UPS 系统中的整流/续流元件
  • 充电器、电机驱动及家用电器控制电路
  • 高频开关场合需要低损耗与快速恢复的整流应用

五、封装与安装注意

DO-201AD 轴向封装提供良好的导热路径和机械强度,便于波峰焊或手工焊接。为获得最佳散热性能,建议:

  • 保证焊点良好并避免过度加热元件体(遵循推荐焊接曲线)。
  • 必要时在散热器或铜箔上增加热阻散布,或者采用并联降额方式提升热稳定性。
  • 在高频或高浪涌应用中,可通过合适的回路布局与抑制网络降低应力。

六、可靠性与使用建议

  • 在长期工作条件下,应对结温进行监控并留有足够的热余量;在高环境温度下对额定电流进行降额处理。
  • 反向恢复可能引起的振荡或电压尖峰,建议在必要场合配合阻容吸收(RC)或缓冲网络。
  • 并联使用时需注意匹配正向压降与散热条件,防止热点与不均流。
  • 选型时若对反向恢复时间、导通损耗或浪涌能力有更严格要求,建议与厂家确认详细曲线与测试条件。

七、采购与替代

ER304_AY_10001 由 PANJIT(强茂)提供,封装为 DO-201AD,适合需兼顾导通损耗与开关性能的中功率整流场合。采购时请确认完整的规格表和出厂测试报告以满足特定应用需求;如需替代件或更高规格型号,可联系供应商获取同类快恢复系列器件建议。

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
