14D680K 产品概述
一、产品简介
14D680K 是一款基于氧化锌（ZnO）压敏电阻（MOV），由 RUILON（瑞隆源）生产，采用插件式封装（引脚间距 P = 7.5mm）。该器件专为电源口过压与雷击浪涌防护设计，能在瞬态过电压发生时快速钳位，保护下游设备与电路元件免受高能冲击损害。
二、主要参数
- 压敏电压（V1mA）：76 V
- 钳位电压（峰值 Vc）：135 V（对应峰值浪涌电流条件）
- 工作电压（直流）：56 V
- 工作电压（交流）：40 V
- 峰值浪涌电流（Ipk）：1 kA
- 能量吸收：21 J
- 静态电容：4.7 nF @ 1 kHz
- 静态功率（最大耗散）：100 mW
- 封装形式：插件（径向引脚），P = 7.5 mm
三、产品特性与优势
- 快速响应：ZnO 材料具有非常快的非线性电压-电流特性，可在短时间内将过电压钳制到安全水平；
- 高能量吸收：单脉冲能量吸收能力达 21J，配合 1kA 峰值浪涌电流，可有效处理常见雷击和开关瞬变；
- 低漏泄及功耗控制：静态功率 100 mW，适合长期并联在线路上工作；
- 插件封装便于替换与维修，引脚间距 7.5mm 兼容多数通孔 PCB 布局；
- 静态电容 4.7nF 对某些对高频敏感的电路会有影响，适合电源类接口而非高速信号线直接并联使用。
四、典型应用
- 交流/直流电源输入保护（工控电源、通信电源、充电设备等）；
- 电源模块和适配器的端口浪涌抑制；
- 建筑物和工业设备的线路防雷辅助防护；
- 与熔断器、TVS 管或气体放电管等协同构成多级防护体系。
五、使用建议与布局注意
- 建议将 14D680K 直接并联安装于电源输入端，靠近被保护设备的电源引入点，以缩短保护路径和降低接地阻抗；
- 为避免连续过热和累积损伤，在高能量环境下应与熔断器或自恢复保险丝配合使用，防止 MOV 在多次浪涌后失效引发安全隐患；
- 由于静态电容较大，不建议在对信号完整性要求高的接口（如高频数据线）直接并联；
- 插件安装时注意焊接温度及时间，避免对压敏体造成热应力；保持良好通风或采用散热结构，以利于热量散逸。
六、可靠性与安全注意事项
- MOV 在经历多次大幅度浪涌后会降额，建议进行合理的选型余量和周期性检查；
- 若用于户外或高雷击风险环境，考虑与气体放电管等器件配合，形成多级钳位以降低单器件承受的能量；
- 设计时遵循相关电气安全规范，必要时选择通过相应认证的器件并在最终设备中加入过温、过流保护措施。
总结：14D680K 以其 76V 压敏电压、135V 钳位电压及 1kA/21J 的浪涌能力，适合用于各种直流/交流电源口的浪涌和雷击防护。合理的布局与配套保护措施能显著提升系统的抗浪涌可靠性与使用寿命。

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.
