KPTVS12VS1UR 产品概述
一、产品简介
KPTVS12VS1UR 是 KUU 推出的一款单向 TVS（瞬态电压抑制）二极管，封装为 SOD-123FL（SMF 系列兼容型）。该器件针对静电放电（ESD）和电源浪涌（浪涌/浪涌电流）提供快速钳位保护，适用于板级、端口和线路的过电压保护，尤其适合 12V 工况的电子系统。
二、主要电气参数
- 极性：单向
- 反向截止电压 Vrwm：12 V
- 击穿电压 Vbr：13.3 V
- 钳位电压 Vc（Ipp）：19.9 V
- 峰值脉冲电流 Ipp：10.1 A
- 峰值脉冲功率 Ppp：200 W（典型脉冲测试条件下）
- 反向漏电流 Ir：2.5 μA（常温）
- 通道数：单路
- 工作温度范围：-55 ℃ ～ +150 ℃
三、主要特性与优势
- 针对 12V 系统优化的偏置与钳位性能，能在较低的触发电压下提供有效保护。
- 钳位电压约 19.9V，能够在浪涌事件中将被保护节点的电压限制在安全范围内，降低对下游器件的应力。
- 200 W 峰值脉冲功率与 10.1 A 的瞬时承受电流能力，适合中小功率浪涌场景（如汽车辅助电路、工业接口电源、通信端口）。
- SOD-123FL 小外形便于高密度 PCB 布局，兼顾散热与占板面积。
- 低漏电流特性有利于低功耗应用与静态电流敏感电路。
四、典型应用场景
- 汽车 12V 辅助电路及车载电子（需注意汽车级认证与具体规范）。
- 通信接口与数据线保护（串行接口、电源输入端）。
- 工业控制与传感器接口的浪涌/ESD 保护。
- 消费电子中的电源保护、连接器和模块防护。
五、封装与机械特性
采用 SOD-123FL（SMF 兼容）表面贴装封装，适合自动贴装与回流焊工艺。封装尺寸小，安装时应尽量靠近被保护引脚或连接器放置以减少走线感应与串扰。
六、布局与使用建议
- 器件应尽量靠近需要保护的引脚或连接器安放，走线尽可能短且宽，以降低寄生电感与阻抗。
- 对于较大能量的浪涌，配合合理的接地面和散热路径（如地铜层和过孔）可提升能量分散能力。
- 在高频或差分信号线路上使用时注意避免影响信号完整性，推荐预留最小走线距离并评估串扰。
- 回流焊温度应符合封装的工艺规范，避免超过器件最高允许温度。
七、可靠性与环境适用
器件工作温度范围宽（-55 ℃ 至 +150 ℃），适用于多种严苛环境。对于关键应用建议结合加速寿命试验与实际环境测试（温度循环、湿热、振动等）验证稳定性。
八、选型要点
选择时关注是否需要单向或双向保护、最大钳位电压是否满足下游器件耐压、峰值脉冲功率与实际浪涌能量匹配，以及封装亮点（安装空间与散热需求）。KPTVS12VS1UR 适合 12V 级别且对钳位电压与响应速度有要求的场合。

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.
