1N5819WS 产品概述
一、产品简介
1N5819WS（DOWO 东沃）是一款小型肖特基势垒二极管，封装为 SOD-323。该器件以低正向压降和良好的开关特性著称，适合低电压、高频环境下的整流、续流与极性保护等应用。体积小、响应快，便于在空间受限的表面贴装电路中使用。
二、主要参数
- 品牌：DOWO（东沃）
- 型号：1N5819WS
- 封装：SOD-323（表面贴装）
- 正向压降（Vf）：约 0.9 V @ 3 A
- 直流反向耐压（Vr）：40 V
- 额定整流电流：1 A（直流）
- 反向漏电流（Ir）：1 mA @ 40 V
- 非重复峰值浪涌电流（Ifsm）：9 A
三、关键特性与优势
- 低正向压降：在导通时降低功耗与发热，有利于提升系统效率。
- 快速切换：肖特基结构带来较小的反向恢复，使其在高频开关环境中表现良好。
- 良好浪涌承受力：9 A 峰值浪涌电流能够应对短时大电流脉冲。
- 小型化封装：SOD-323 适合高密度贴片设计，便于自动化生产与成本控制。
四、典型应用
- 低压开关电源输出整流与续流二极管
- DC-DC 变换器、逆变器（低电压、高频场合）
- 电池与电源的极性保护、防反接电路
- 便携设备与消费电子的电源管理模块
五、封装与可靠性
SOD-323 小封装在热阻及功率散逸方面受限，设计时需注意焊盘与散热路径的优化。DOWO 的产品通常符合表贴生产与回流焊流程要求，建议参考厂商数据手册进行回流温度曲线与可靠性筛选。
六、使用建议
- 在接近额定电流工作时，应评估实际结温和散热能力，必要时采用更大封装或并联方案。
- 关注反向漏电流对待机功耗的影响，尤其在高阻或高电压蓄电场合。
- 对于频繁大电流冲击场合，检查浪涌能量与器件寿命匹配。

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.
