K14 肖特基二极管（DOWO/东沃）产品概述
一、产品简介
K14 为 DOWO（东沃）出品的独立式肖特基整流二极管，SOD-123 小型表贴封装。其典型正向压降为 0.7V（700mV）@1A，最大反向耐压 40V，直流反向电流为 10mA@40V，额定整流电流 1A。器件针对中低压、需要低正向压降与快速恢复特性的场合设计，适合空间受限的消费电子与电源模块应用。
二、主要特性
- 正向压降：700mV @ 1A，降低整流损耗，有助于提高效率与节省电能。
- 反向耐压：40V，满足常见 12V/24V 系统的保护与整流需求。
- 反向漏电：10mA @ 40V，介于一般肖特基器件范围内；在高阻电路中需注意漏电影响。
- 封装：SOD-123，体积小、便于自动化贴装，适合高密度 PCB 布局。
- 独立式器件，便于单点替换与模块化设计。
三、典型应用场景
- 电源整流与续流：开关电源次级整流、低压整流回路。
- 反接保护/防反充：用于电池供电系统、防止反向电流损坏电路。
- 电源选择与隔离：在多路电源切换或 OR-ing 电路中作为低压降整流元件。
- 消费类电子：便携设备、充电器、车载电子等体积受限且要求效率的场合。
四、封装与热管理建议
SOD-123 为小型表贴封装，散热能力受限。建议在 PCB 设计中：
- 增加器件下方与引脚处的铜箔面积及过孔，以降低结温。
- 在连续 1A 工作条件下关注结温上升，必要时考虑散热片或更大铜箔。
- 按照常见 SMT 工艺进行回流焊，遵循元件湿热敏等级与厂方回流曲线（详见原厂 datasheet）。
五、使用注意事项
- 反向漏电较大时（10mA@40V），不适合对漏电敏感的高阻输入端或计量电路。
- 尽量避免长期超额定电流与过高结温以延长可靠性；设计时留有余量并考虑浪涌电流。
- 观察极性标识（SOD-123 封装上有极性标记），贴装时防止反位导致损坏。
- 储存运输按常规半导体湿敏元件处理，避免潮湿与静电损伤。
六、型号与采购信息
型号：K14
品牌：DOWO（东沃）
封装：SOD-123
应用：低压整流、反接保护、便携电源等场合。
建议在设计前参照完整 datasheet 获取浪涌电流、最大结温、热阻、封装尺寸及回流曲线等详细参数，以确保设计可靠性与符合生产工艺。

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.
