ER504_AY_10001 产品概述

ER504_AY_10001 是 PANJIT(强茂)出品的一款快恢复、高效率整流二极管,额定直流整流电流 5A、重复反向耐压 400V,适用于中高压开关电源与整流场合。典型正向压降 1.25V(IF=5A),反向泄漏电流仅 1μA(VR=400V),反向恢复时间 Trr≈35ns,工作结温范围宽(-55℃ ~ +150℃),封装为 DO-201AD(T/B)。

一、主要性能与优势

  • 低正向压降(1.25V@5A):减少导通损耗,提高整机效率,尤其在输出整流与高电流路径上有明显优势。
  • 快速恢复(Trr≈35ns):在开关频率较高的电源中显著降低开关损耗和交越恢复相关的发热与 EMI。
  • 低反向泄漏(1μA@400V):在高压工况下保持低静态损耗,适合高压整流与保护应用。
  • 宽工作结温(-55℃~+150℃):适应严苛环境与高温运行需求,可靠性高。

二、电气参数要点

  • 正向压降 Vf:1.25V(典型值,IF=5A),请按应用留有余量进行热设计。
  • 反向耐压 Vr:400V,适用于 200V~400V 直流母线或整流链路。
  • 直流整流电流 IF:5A 连续,适合中等功率的整流与自由轮回场合。
  • 反向电流 Ir:1μA@400V(典型),在高阻态下泄漏小,利于提高空载或待机效率。
  • 反向恢复时间 Trr:≈35ns,适应较高开关频率(相较传统慢恢复整流二极管有明显提升)。

三、封装与热管理

  • 封装:DO-201AD(轴向引线),适合通孔安装,机械强度好,便于散热与维修更换。
  • 热管理建议:尽量保证良好散热路径,增加导线/铜箔散热面积或强制风冷;在高温或接近额定电流的场合推荐适当降额(留余量),以延长器件寿命。
  • 并联注意:若需并联提升电流,须考虑电流均流措施(如小阻值串联或热耦合),否则易产生不均流导致过热。

四、典型应用场景

  • 开关电源(SMPS)输出整流与续流二极管
  • 输入整流与功率因数校正(PFC)电路中高压整流
  • 逆变器与电机驱动的自由轮回路径
  • 充电器、适配器、UPS 等中高功率电源系统
  • 保护电路、极性保护与高压整流模块

五、设计与使用建议

  • 在高频切换场合充分利用其快恢复特性,可减小二次开关损耗与 EMI。
  • 正向压降随电流与温度变化,请在电源效率计算中采用典型与最大值进行裕量设计。
  • 长期可靠性考虑:避免常态长期在最高结温下运行,建议留有热裕度并遵循 PCB 布局的散热优化原则。
  • 安装与焊接:遵循厂商的焊接/温度曲线和清洁度要求,保持引脚与焊盘良好接触。

六、选型与采购提示

ER504_AY_10001 以其 400V 耐压、5A 电流、低 Vf 与快恢复特性,适合在追求效率与可靠性的中高压整流应用中替代传统慢恢复二极管。订购时请确认包装(DO-201AD T/B)与出厂测试资料,必要时索取产品特性曲线(Vf–If、Ir–Vr、Trr 曲线)以便在具体电路中进行精准热与电性能评估。

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
