KPESD3V3S1UL 产品概述
一、产品简介
KPESD3V3S1UL 是 KUU 品牌的一款单向瞬态电压抑制（ESD）保护器件，采用 DFN1006 超小封装，专为高速数据线与敏感引脚提供低电容、高可靠性的静电与脉冲浪涌保护。器件工作电压 Vrwm 为 3.3V，击穿电压 Vbr 4.2V，具有快速响应与稳定的钳位能力，适合移动设备、通信接口与消费电子等场景。
二、主要参数（关键电气特性）
- 极性：单向
- 反向截止电压 Vrwm：3.3 V
- 击穿电压 Vbr：4.2 V
- 钳位电压（典型）：14 V
- 峰值脉冲电流 Ipp：4 A（单次 IEC 标准脉冲）
- 峰值脉冲功率 Ppp：56 W
- 反向电流 Ir：100 nA（在 Vrwm 条件下）
- 结电容 Cj：0.4 pF（低容，适合高速信号）
- 通道数：单路
- 工作温度范围：-55 ℃ ~ +125 ℃ (Tj)
- 防护等级：符合 IEC 61000-4-4（电快速脉冲）和 IEC 61000-4-2（ESD）标准
三、产品特点与优势
- 超小封装（DFN1006），占板面积小，便于移动终端与密集 PCB 布局。
- 低结电容（0.4 pF），对高速差分或单端信号影响极小，适配 USB、HDMI、MIPI、SDA/SCL 等高速接口。
- 单向结构适用于带地参考的信号线，响应迅速，能在静电事件或瞬态过电压下将峰值能量钳制至安全范围。
- 低反向漏电（100 nA），在待机或低功耗场景下对系统影响小。
- 宽温工作范围与高脉冲承受能力（56W），保证工业级与消费级产品的长期可靠性。
四、典型应用
- 智能手机与平板的 I/O 引脚保护（触摸、按键、通信口）
- USB/串口、相机模组、传感器接口保护
- 工业控制与物联网终端的端口防护
- 任何需要在 3.3V 电源域内保护单端信号线的场合
五、封装与布局建议
器件采用 DFN1006（小型无引脚封装），建议将器件尽可能靠近被保护引脚布局，地线短且粗以降低回路阻抗；单向器件的阴极连接至待保护线，阳极接地。推荐在 PCB 布局中避免将敏感信号环路穿过器件旁边，以获得最佳抗干扰效果。
六、可靠性与合规
KPESD3V3S1UL 经过 IEC 61000-4-2 和 IEC 61000-4-4 级别测试验证，能够满足常见静电放电与电快速脉冲干扰的防护要求，适配工业与消费电子环境的电磁兼容设计需求。

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.
