1N5819W 产品概述（GOODWORK 固得沃克）
一、概述
1N5819W 是 GOODWORK（固得沃克）推出的一款独立式肖特基整流二极管，采用 SOD-123 小封装，面向开关电源、续流和整流等高效率整流场合。该器件具有低正向压降和快速恢复特性，适合在低压大电流和脉冲条件下工作。
二、主要电气参数
- 整流电流（Io）：1A（连续）
- 正向压降（Vf）：0.58V @ 1A
- 直流反向耐压（Vr）：40V
- 反向电流（Ir）：50μA @ 40V
- 非重复峰值浪涌电流（Ifsm）：9A
- 工作结温范围：-65℃ ~ +125℃
- 封装：SOD-123，独立式器件
三、产品特点
- 低正向压降：在大电流下减小导通损耗，提高整流效率，利于散热管理。
- 快速恢复／肖特基特性：在开关转换时损耗和反向恢复时间小，降低开关损耗和电磁干扰。
- 小体积封装：SOD-123 便于高密度贴片装配，适合空间受限的电路板设计。
- 宽温度范围：可在-65℃至+125℃的环境下工作，可靠性高。
四、典型应用场景
- 开关电源（SMPS）二次侧整流
- DC-DC 转换器续流二极管
- 反向保护与极性保护电路
- 低压大电流整流场合，如便携设备、通信设备电源
五、热设计与降额建议
在连续1A工作时需关注封装热阻和PCB散热。建议：
- 在铜箔上留出散热垫并增加过孔，改善热传导；
- 若工作环境温度较高或占空比/脉冲较重，应按结温限制降额使用，或并联器件分担电流；
- 评估焊盘与周围金属散热面积以保证结温不超过125℃。
六、封装与焊接注意事项
SOD-123 为表贴封装，推荐按厂家给出的焊盘尺寸与回流曲线进行贴装与回流焊。避免过热长时间停留，防止封装变形或内部应力。储存与使用中注意防潮包装，必要时回潮焙烘处理。
七、可靠性与测试
器件适用工业级温度范围，建议在最终产品中进行功耗、热测和冲击电流测试（Ifsm 情形下短时脉冲），确认在实际工况下的温升与反向漏电是否满足设计要求。
八、采购与型号识别
型号：1N5819W；品牌：GOODWORK（固得沃克）；封装：SOD-123。订购时请注明完整型号与封装，以确保拿到与样片一致的参数与封装版本。
如需参考封装尺寸图、典型特性曲线或公司器件的详细数据手册（Datasheet），可向 GOODWORK 厂家或授权分销商索取以便进行更精确的热设计与电气仿真。

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.
