K1N5819HWS-7-F 产品概述
一、概述
K1N5819HWS-7-F 是 KUU 品牌的一款独立式肖特基整流二极管，封装为 SOD-323，额定直流反向耐压 40V，整流电流 1A，非重复峰值浪涌电流 Ifsm 10A。该器件在高电流条件下表现出较低的正向压降（示例规格为 900mV@3A），适用于体积受限且对正向压降有一定要求的低压整流与保护场景。
二、主要电气参数
- 正向压降：约 0.9V @ 3A（在较低电流时压降显著降低）
- 直流反向耐压 Vr：40V
- 最大整流电流：1A（连续）
- 反向漏电流 Ir：1mA @ 40V（反向电压接近最大值时漏电较明显）
- 峰值浪涌电流 Ifsm：10A（单脉冲）
- 封装：SOD-323（小型贴片）
三、典型应用场景
- 低压电源整流、二次侧整流
- 反向极性保护、续流二极管（freewheeling）
- 电池供电设备、便携式电子产品中的低压整流与保护
- 开关电源辅助整流、降压模块保护
四、设计与热管理建议
- SOD-323 为小型封装，热阻较大，靠近额定电流工作时须注意结温与散热。示例计算：若按 1A 且 Vf≈0.9V，功耗约 0.9W，单颗器件在无额外散热时难以长期承受，建议减小平均电流或在 PCB 上扩展散热铜箔（尤其是阴极/焊盘区域）。
- 对于脉冲性浪涌（Ifsm），器件能承受短时高峰，但应严格遵循脉冲宽度和频率的限制。
- 在高反向电压工作时漏电流会增加（规格给出 1mA@40V），若系统对漏电敏感，应选取更大耐压或低漏电型号。
五、封装与可靠性注意
- 封装 SOD-323，适合高密度贴片。焊接时建议按通用回流工艺（请参考厂家具体回流曲线，避免超过峰值温度限制）。
- 存储与工作温度范围请参照完整规格书（常见肖特基范围为 -55℃ ~ +150℃，但以厂方数据为准）。
- 在选型时注意器件的反向漏电、工作温度对参数的影响，必要时做实际电路测量以确定可靠性余量。
六、选型建议与结论
K1N5819HWS-7-F 适合用于 40V 以下、峰值不常超过额定值且空间受限的整流与保护场合。若系统需长期 1A 以上连续电流或对反向漏电严格限制，应考虑更大封装或额定更高的型号。最终选型请结合实际工作电流、结温及 PCB 散热能力，并参照 KUU 提供的完整数据手册进行验证。

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.
