1N5401 产品概述
一、产品简介
1N5401 是 DIOTEC（德欧泰克）提供的一款通用整流二极管，封装为 DO-201 轴向引线形式。该器件面向中功率整流场合，具有可靠的导通和耐压特性，适合工业电源、充电器及一般功率整流应用。
二、主要电气参数
- 正向压降（Vf）：1.2V @ IF = 3A
- 直流反向耐压（Vr）：100V（最高反向电压）
- 额定整流电流：3A（连续）
- 反向漏电流（Ir）：5µA @ VR = 100V
这些参数表明器件在中等电流与中等电压工况下有良好表现，反向漏电小，适合直流整流与开关整流的常规用途。
三、封装与机械特性
DO-201 为轴向引线玻璃钝化或金属化封装，结构坚固、耐热性好，便于手工焊接或波峰焊。该封装利于通过引线向外散热，但在高功率应用中仍需注意散热设计与空气流动。
四、典型应用场景
- 开关电源与线性电源的整流输出
- 充电器与电池管理的整流与保护回路
- 电机驱动的回馈/续流二极管（需注意脉冲能力）
- 工业电源、家电及照明驱动等中功率整流场合
五、热管理与使用注意事项
1N5401 在 3A 连续工作时正向压降约为 1.2V，会产生显著功耗（P = Vf × IF）。设计时应评估器件结温并提供良好通风或散热路径；在脉冲或浪涌工况下，应参考厂家数据手册中的峰值脉冲电流与重复率限制。长期在高温、高电压下工作会增加漏电与失效率，布局时保持适当间距并避免过度焊接热负荷。
六、选型建议与替代型号
若需更高耐压，可考虑同系列更高 Vr 的型号；若要更低正向压降或更小功耗，可优先选用石英（Schottky）肖特基二极管，但需注意肖特基的反向耐压通常较低。购买与设计前，建议下载 DIOTEC 官方数据手册，确认脉冲峰值、结温范围及包装尺寸以满足实际工况与可靠性要求。
七、结论
DIOTEC 的 1N5401（DO-201）是一款可靠、易用的通用整流二极管，适合多数中等功率整流应用。合理的热设计和参考厂家数据手册的极限参数，是确保长期稳定运行的关键。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
