1N5819HW 产品概述
一、产品简介
1N5819HW 是 GOODWORK（固得沃克）推出的一款独立式肖特基整流二极管，采用小型 SOD-123 封装，额定整流电流 1A、直流反向耐压 40V。该器件针对低压高速整流和反向保护场合设计，具有较低的正向压降和良好的浪涌承受能力，适用于便携式设备、电源模块及信号保护电路。
二、主要参数
- 封装：SOD-123（小封装、表面贴装）
- 工作结温范围：-65℃ ~ +125℃
- 额定整流电流：1A（连续）
- 非重复峰值浪涌电流 Ifsm：9A
- 直流反向耐压 Vr：40V
- 正向压降 Vf：580mV @ 1A
- 反向电流 Ir：50µA @ 40V（常温）
三、主要特性与优势
- 低正向压降：在 1A 流过时 Vf≈580mV，减少整流损耗，提高效率。
- 肖特基结构：无恢复时间或恢复极短，适合高频开关和快速脉冲场合。
- 良好的浪涌能力：9A 非重复峰值浪涌，能承受启动或短时冲击电流。
- 宽温度范围：-65℃ 至 +125℃，在较严苛环境下仍能稳定工作。
- 小型封装：SOD-123 占板面积小，利于高密度 PCB 布局和自动化贴装。
四、典型应用场景
- 开关电源二次侧整流与续流二极管
- DC-DC 转换器与降压模块输出整流
- 反向电源保护与二极管 OR-ing 应用
- 便携式与消费电子产品（充电器、移动电源）
- 信号线或接口的浪涌/反向保护
五、使用建议与可靠性注意事项
- 热管理：尽管额定电流为 1A，但在连续工作或高环境温下应进行降额设计并通过铜箔散热或布大焊盘降低结温。
- 反向漏流随温度显著上升，设计时应考虑高温工况下 Ir 的影响，特别是在高阻输入或待机电路中。
- 浪涌保护：Ifsm 为非重复峰值，避免在电路中频繁出现超过额定浪涌的情况，以免缩短寿命。
- 焊接工艺：遵循 SOD-123 的回流温度曲线，避免过热影响可靠性。建议在元件数据手册中查阅焊接和储存条件。
六、封装与订购
该型号采用 SOD-123 小型表贴封装，适配常用贴装和回流工艺。GOODWORK 提供散装和卷带（Tape & Reel）包装，便于量产采购与自动化贴装。订购与技术支持请联系 GOODWORK 或其授权分销商，获取完整规格书和 PCB 封装建议图。
总结：1N5819HW 在低压、高频和空间受限的应用中表现出色，兼具低压降、快速响应和良好的浪涌承受能力，是小功率整流与保护电路的可靠选择。

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.
