PESD15VS2UT 静电放电防护器件产品概述
一、产品基本定位
PESD15VS2UT是东沃（DOWO）品牌推出的双向单路静电放电（ESD）防护器件，属于瞬态电压抑制（TVS）二极管范畴。产品专为电子电路中的瞬态干扰防护设计，可有效抑制ESD、电快速瞬变脉冲群（EFT）及浪涌等电磁干扰，保障敏感电子元件（如MCU、传感器）稳定运行。采用SOT-23小型封装，适配各类小型化、高密度电子设备。
二、核心性能参数解析
该器件平衡“防护有效性”与“电路兼容性”，核心参数如下：
- 电压与击穿特性：
- 反向截止电压（Vrwm）=36V：正常工作时反向偏置不导通，不影响电路信号传输；
- 击穿电压（Vbr）=38V：脉冲干扰到来时快速击穿导通，实现电压钳位；
- 钳位电压（Vc）=56V：脉冲峰值电流下的最高电压，可有效限制后级电路过压风险。
- 脉冲耐受能力：
峰值脉冲电流（Ipp）=8A，峰值脉冲功率（Ppp）=450W，可承受较强瞬态冲击。 - 电学兼容性：
- 反向漏电流（Ir）=500nA：低漏电流避免器件自身功耗影响电路；
- 结电容（Cj）=90pF：适配10MHz以下信号（如低速数字信号、模拟传感器信号），对高频信号衰减影响小。
- 环境与通道特性：
单路通道设计，适合单信号线路精准防护；工作温度范围-55℃~+125℃，宽温适配工业/车载环境。
三、防护标准与能力
严格遵循国际电磁兼容（EMC）标准，覆盖三类核心瞬态干扰：
- ESD防护：符合IEC 61000-4-2，应对接触放电（±8kV）、空气放电（±15kV）；
- EFT防护：满足IEC 61000-4-4，抑制1MHz以上重复脉冲群干扰；
- 浪涌防护：符合IEC 61000-4-5，承受雷击感应、电源开关浪涌冲击。
四、典型应用场景
- 消费电子：手机/平板的USB、音频接口，笔记本摄像头模组防护；
- 工业控制：PLC I/O端口、RS485/232通信接口、传感器信号线路防护；
- 通信设备：路由器/交换机以太网端口、基站射频接口防护；
- 汽车电子：车载显示屏、CAN总线、车载摄像头接口防护（宽温适配车载环境）。
五、封装与可靠性优势
- SOT-23封装：体积小巧（2.9×1.6×1.1mm），适配贴片自动化生产，降低设备体积与成本；
- 高可靠性：宽温范围满足工业/车载严苛环境，器件一致性好，批量应用性能稳定。
六、品牌与市场价值
东沃（DOWO）作为国内防护器件专业制造商，PESD15VS2UT具备高性价比、替代进口优势：性能符合国际标准，易采购、易焊接，适合中小批量至大规模生产，为客户提供高效电路防护解决方案。
该器件通过精准的参数设计与封装优化，可广泛适配各类电子设备的瞬态干扰防护需求，是工业、消费、汽车电子领域的实用选择。

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.
