LC05CI 产品概述

一、产品简介

LC05CI 是 TECH PUBLIC(台舟电子)出品的一款单路瞬态电压抑制器(TVS)器件,针对 5V 级信号/电源线的浪涌和静电放电保护进行优化。器件采用 SOD-323 小型贴片封装,适合空间受限的消费电子与工业接口防护场合。

二、主要参数及其意义

  • 钳位电压(Vc):16 V(在 8/20 μs 波形下测得的峰值钳位电压),表示器件在吸收脉冲能量时对被保护节点的最高限制电压。
  • 击穿电压(Vbr):6 V,表示器件开始进入雪崩导通的阈值。
  • 反向截止电压(Vrwm):5 V,器件在正常工作状态下允许的最大反向工作电压,适配 5 V 级电路。
  • 峰值脉冲功率(Ppp):300 W @ 8/20 μs,表明器件对短时大能量脉冲(如雷击感应或浪涌)的吸收能力。
  • 结电容(Cj):典型 1 pF,极低的并联电容使其适用于高速数据线(如 USB、串行总线等),对信号完整性影响小。
  • 反向电流(Ir):200 nA,表明在 Vrwm 下的泄漏电流很小,有利于低功耗与精密电路的稳定性。
  • 通道数:单路(单通道保护)。
  • 防护等级:符合 IEC 61000-4-2(静电放电)、IEC 61000-4-4(闪络/快速瞬变)标准,满足常见工业与消费类电磁脉冲抗扰度要求。
  • 封装:SOD-323,适合自动贴装与紧凑 PCB 布局。

三、典型应用场景

  • USB、GPIO、UART 等 5V/低电容高速信号线的静电与浪涌保护。
  • 5V 电源总线的瞬态抑制,保护后端电源管理 IC、MCU 或传感器。
  • 工业现场接口与板级输入端口(如传感器引脚、继电器驱动前端)的过压保护。
  • 消费电子(移动设备、外设)、通信设备与测试仪器的 ESD/EFT 防护。

四、设计与使用建议

  • 连接方式:器件建议以单向 TVS 方式使用(通常将器件阴极接被保护线路,阳极接地),在正向浪涌时实现快速钳位导通。
  • 布局:将 LC05CI 放置于外部连接器和被保护芯片之间,且尽量靠近输入端/连接器,走线尽量短且宽,地线采用单点或灌铜接地并加短回流路径。
  • 热与能量处理:300 W@8/20µs 为短时能量吸收能力,若预期更长或更频繁的大能量冲击,应在系统级考虑更高功率器件或并联/级联保护策略。
  • 信号完整性:1 pF 的低结电容可最大限度降低对高速信号的影响,但在差分高速接口应评估对眼图/延迟的实际影响。
  • 泄漏与偏置:200 nA 的反向电流适合低功耗应用,但在超低泄漏要求的精密测量路径仍需评估。

五、封装与可靠性认证

LC05CI 采用 SOD-323 表面贴装封装,便于自动化贴装与回流焊工艺。产品通过 IEC 61000-4-2 / IEC 61000-4-4 等抗扰度标准测试,适配工业与消费环境的 ESD/EFT 抗扰要求。

六、选型注意事项与总结

  • 若保护对象为 5 V 工作电压的数字或电源线,LC05CI 的 Vrwm=5 V 与 Vbr≈6 V 匹配良好;但需确认钳位电压 16 V 是否被下游电路所能承受。
  • 对更严格的钳位要求或更高的能量吸收需求,可考虑更大功率或更低钳位的 TVS 器件。
  • 若保护双向信号(交流/差分)或无需恒定极性,应选择双向 TVS 型号。

总结:LC05CI 为一款面向 5V 级接口的低电容、低泄漏、具有良好瞬态吸收能力的单路 TVS 器件,适用于对空间、信号完整性和抗 ESD/EFT 有综合要求的应用场景。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
