MUR460_AY_00101 产品概述
一、产品简介
MUR460_AY_00101 是 PANJIT（强茂）生产的一款快恢复/高效率二极管，600V 额定反向耐压、额定整流电流 4A，采用 DO-201AD 轴向封装。该器件针对高频开关应用进行了优化，在保持较低正向压降的同时具备较快的反向恢复特性，适合开关电源、功率因数校正、反激/正激拓扑和各种整流/吸收场合。
二、主要规格参数
- 正向压降 (Vf)：1.28V @ 4A
- 直流反向耐压 (Vr)：600V
- 整流电流：4A
- 反向电流 (Ir)：5μA @ 600V
- 反向恢复时间 (Trr)：50ns
- 工作结温范围：-55℃ ~ +150℃
- 非重复峰值浪涌电流 (Ifsm)：125A（单次脉冲）
- 封装：DO-201AD（轴向）
三、关键特性与优势
- 低正向压降：1.28V 在 4A 工作点时，有助于降低导通损耗，提高系统效率。
- 快恢复时间：50ns 的反向恢复减少开关损耗与电磁干扰，适合高频整流与自由轮回路。
- 低反向泄漏：600V 时仅 5μA，有利于高压回路的静态漏电控制。
- 良好的浪涌能力：125A 峰值浪涌允许短时承受启动或故障电流冲击。
四、典型应用
- 开关电源（SMPS）整流与续流
- 功率因数校正（PFC）电路
- 逆变器与电机驱动中的快恢复整流
- 电池充电器、适配器及工业电源模块
五、封装与热管理建议
DO-201AD 轴向封装便于通孔安装与手工/波峰焊接。注意 Vf×I 在额定整流电流下产生显著耗散（约 5.12W），需：
- 扩大 PCB 铜箔面积并设计热铺铜与热过孔；
- 在必要时使用夹持式散热或热沉；
- 确保工作结温不超过 +150℃，并在高温环境下进行适当降额。
六、使用注意事项
- 非重复峰值浪涌 Ifsm 为单次脉冲能力，重复冲击请按厂方曲线降额。
- 高 dv/dt 场合下虽然恢复快，但仍建议对关键节点采取 RC 吸收或缓冲来抑制尖峰。
- 存储与焊接时遵循封装耐温与清洁要求，避免机械应力损伤引脚。
总结：MUR460_AY_00101 在高压、高频电源场合兼顾低导通损耗与快速恢复特性，是要求效率与开关性能平衡的可靠选择。在设计中注意热管理与浪涌降额，可充分发挥其性能优势。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
