CESD15VD5 产品概述
一、主要参数与标称值
CESD15VD5（品牌：CJ/长晶，封装：SOD-523）是一颗单路、单向TVS二极管，面向对抗瞬态过压和静电放电的保护场景。关键电气参数如下：钳位电压 Vc = 34V；击穿电压 Vbr ≈ 16.7V；反向截止电压（稳态电压） Vrwm = 15V；峰值脉冲功率 Ppp = 323W；峰值脉冲电流 Ipp = 9.5A；反向漏电流 Ir = 1µA；结电容 Cj = 48pF；符合 IEC 61000-4-2 静电放电防护等级。
二、工作原理与极性说明
作为单向TVS，CESD15VD5 在正常工作时以 Vrwm = 15V 的反向偏置工作；当输入电压超过击穿电压（约16.7V）并在浪涌发生时，器件进入雪崩导通，将瞬态能量钳位到约34V，从而把危害能量导入地线，保护下游电路。器件单向极性适合直流电源或单极数据/通信线保护；若需双向保护，应选用双向型TVS。
三、性能亮点与优势
- 高脉冲能量吸收：Ppp = 323W，可承受较大瞬态能量与高幅值脉冲。
- 高峰值冲击能力：Ipp = 9.5A，适用于常见的浪涌与ESD事件缓冲。
- 低漏电流：Ir = 1µA，在稳态下对系统功耗影响极小，适合电池供电设备。
- 小封装：SOD-523 封装体积小，适合空间受限的便携类或高密度PCB布局。
- 通过 IEC 61000-4-2 标准认证，具备良好的静电放电防护能力。
四、典型应用场景
- USB、串口、GPIO、SIM 卡、摄像头等外部引脚的ESD/浪涌保护（特别是单向供电/信号线）。
- 手机、平板、可穿戴设备等受限空间的保护电路。
- 工业控制与仪表输入保护、消费电子接口保护等需要低漏电和小封装的场合。
五、使用建议与布局注意事项
- 布局：将 CESD15VD5 尽可能靠近被保护的外部连接器或接口放置，焊盘到器件引脚间走线要尽量短且粗，以缩短浪涌回路，降低钳位电压。
- 与地的连接要低阻抗，若可能为器件附近提供充足的地回流路径（多层板接地掏空/过孔）。
- 对高速信号线而言，48pF 的结电容可能引起信号完整性影响；用于高速差分对或射频链路前应慎重评估或选型低电容版本。
- 若用于双向或交流保护，需改用双向TVS；若需更高脉冲能量，可并联或选更大封装的器件，注意热耗及共享电流不均问题。
- 选型时核对测试条件（脉冲波形、脉冲宽度等）以确保 Ppp/Ipp 数据与实际浪涌类型相符。
六、封装与选型要点
SOD-523 小型封装适用于表面贴装自动化生产和高密度电路板。但其散热和功率承载能力受限，长时间或重复的大能量冲击可能需要更大封装或额外的热管理措施。总体而言，CESD15VD5 在要求小尺寸、低漏电、高ESD耐受的单路保护场合具有较好的性价比与实用性。

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.
