SS14L（KUU）产品概述
一、概述
SS14L 为 KUU 推出的 SOD-123FL 封装肖特基整流二极管，采用金属硅结工艺，属于多数载流子传导器件。器件具有低正向压降、快速恢复特性和较高浪涌能力，特别适合低压、高频电源与保护电路的整流与续流应用。
二、主要参数
- 型号：SS14L（品牌：KUU）
- 正向压降：Vf = 0.55 V @ 1 A
- 直流反向耐压：Vr = 40 V
- 连续整流电流：IF = 1 A
- 反向漏电流：Ir = 300 μA @ 40 V
- 非重复峰值浪涌电流：Ifsm = 25 A
- 工作结温范围：-55 ℃ ~ +125 ℃
- 封装：SOD-123FL（表面贴装）
三、产品特点
- 低正向压降：0.55 V@1 A，有助于降低导通损耗和发热，提高整机效率。
- 肖特基特性：多数载流子传导，反向恢复时间极短，适合高频开关场景。
- 高浪涌能力：Ifsm = 25 A，能承受短时启动或过载冲击。
- 小体积表贴：SOD-123FL 适合密集装板和自动化贴装，利于体积受限产品设计。
- 宽温区间：-55 ℃ 至 +125 ℃，能在工业类环境中稳定工作。
四、典型应用
- 开关电源（低压次级整流）
- DC-DC 变换器、升降压模块
- 高频逆变器与续流二极管
- 极性/反接保护、输入保护电路
- 便携式电源、充电器及消费类电子
五、封装与安装建议
- 采用 SOD-123FL 表贴封装，建议在 PCB 设计时保持走线最短以降低寄生电感。
- 为保证散热与可靠性，可在焊盘下方或周围适当增加铜箔面积并与散热层连接。
- 焊接时遵循标准无铅回流焊工艺，避免长时间过高温度导致器件应力。
- 贴装时注意极性标识，避免反向安装造成器件损坏。
六、可靠性与注意事项
- 反向漏电随温度上升会增加，长期在高温高压下工作需留有安全裕度。
- 虽具有较高浪涌能力，但应避免超出 Ifsm 指定的瞬态应力以延长寿命。
- 在设计中考虑浪涌抑制与合理的散热措施，可提高系统稳定性与可靠性。
以上为 SS14L（KUU）在常见应用中的性能与使用要点概述，适用于需要低压降、高频整流与保护的电子设计参考。

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.
