LC05CI 产品概述
一、产品简介
LC05CI 是 Leiditech（雷卯电子）推出的一款小体积双向 TVS（瞬态电压抑制器），适用于 5V 等级的信号/电源保护。器件采用 SOD-323 封装，专为对抗瞬态过压、静电放电（ESD）和浪涌（Surge）干扰设计，符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 等抗扰标准。
二、主要电气参数
- 类型：双向 TVS（单路）
- 反向截止电压 Vrwm：5V
- 击穿电压 Vbr(min)：6V
- 钳位电压（典型）：25V（在规定测试电流下）
- 峰值脉冲功率 Ppp：450W @ 8/20μs
- 峰值脉冲电流 Ipp：18A（常见规格标注 10/1000μs 或 10/1000μs 条件下）
- 反向电流 Ir：500nA（在 Vrwm 条件下）
- 结电容 Cj：约 2pF（便于高速信号应用）
- 封装：SOD-323
三、核心特性与优势
- 小体积封装（SOD-323），便于高密度 PCB 布局与自动贴装生产。
- 双向设计，适合对称差分或无极性的信号/电源线路保护，无需关注极性安装。
- 低结电容（约 2pF），对 USB、串口、音频等高速信号影响小，信号完整性好。
- 满足 IEC 61000-4-2/4/5 标准，具备良好的 ESD、EFT 与浪涌防护能力。
- 低漏电流（500nA），对低功耗设备影响微小。
四、典型应用场景
- USB、TTL/串口等 5V 信号接口的防护
- 智能终端、移动设备、便携式仪器的外接接口保护
- 工业控制与楼宇自控中对抗电磁干扰与浪涌的输入端保护
- 通信设备、传感器节点和差分信号线的防护
五、布局与使用建议
- 尽量靠近被保护的接口或电路放置器件，缩短走线并减小环路电感，以提高钳位效率。
- 对地连接应采用宽短铜箔，保证低阻抗接地路径；若是浮地系统，按系统拓扑选择合适接地策略。
- TVS 为瞬态保护器件，不宜作为持续电流承载元件；长期超过 Vrwm 的偏压会导致热耗损和性能下降。
- 在对高速信号使用时，可结合阻抗匹配措施（如串联阻抗）以兼顾保护与信号完整性。
- 注意钳位电压为瞬态下的最大保护电压，仍需在系统设计中留有裕量，避免对下游器件造成损伤。
六、注意事项
- 在选择器件前确认测试条件（Pp、Ipp 的脉冲波形与持续时间），并基于系统可能出现的最大浪涌进行裕量设计。
- SOD-323 封装散热能力有限，连续或反复高能脉冲会影响寿命，应在系统层面做热和应力评估。
- 若用于差分线对（如 USB 两线保护），建议将一只器件并联到两线与地的结构或采用差分配置的保护方案。
LC05CI 以其小型化、低电容与符合多项 IEC 标准的抗扰能力，是 5V 等级接口与敏感信号线路进行瞬态抑制的可靠选择。若需更详细的典型电路、波形测试或封装引脚图，请告知具体应用场景以便提供针对性建议。

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.
