GBLC05CI-LF-T7 产品概述

一、产品简介

GBLC05CI-LF-T7 是友台半导体(UMW)推出的一款超低电容瞬态电压抑制器(TVS)阵列,专为便携式电子产品与智能手机等对信号完整性与抗静电要求高的应用设计。器件提供单向与双向配置选择,能够在 8/20μs 波形下提供高达 250W 的浪涌吸收能力。SOD-323 小型封装便于在空间受限的移动设备上实现可靠防护。

二、主要特性

  • 极性:双向(Bidirectional),适用于双向信号线及数据总线保护。
  • 反向截止电压(Vrwm):5V,适配 5V 工作电压系统。
  • 击穿电压(VBR):6V(典型),启动钳位前的稳态特性良好。
  • 钳位电压(Vc):9.8V(典型),在浪涌时限制电压峰值保护下游器件。
  • 反向漏电流(Ir):5μA(典型),满足移动设备对低静态功耗的要求。
  • 结电容(Cj):0.6pF,超低电容设计对高速信号影响极小。
  • 防护等级:符合 IEC 61000-4-2(静电放电)与 IEC 61000-4-4(电快速瞬变)测试要求。
  • 额定能量:8/20μs 波形下 250W 峰值能力。
  • 封装:SOD-323,适合贴片自动化生产与小型化布局。

三、典型应用

  • 智能手机、平板及便携式多媒体终端的外部接口(耳机、充电口、数据口)保护。
  • 高速数据线(USB、MIPI、LVDS 等)与信号接口的瞬态抑制,特别适合对电容敏感的差分/单端高速线路。
  • 可穿戴设备、蓝牙模块和物联网终端的静电与浪涌防护。

四、电气参数与性能(要点)

  • Vrwm = 5V,适配 5V 总线及信号。
  • VBR ≈ 6V,触发迅速。
  • Vc ≈ 9.8V(在规定电流下),有效限制故障时电压。
  • Ir ≤ 5μA,低漏电减少待机功耗。
  • Cj ≈ 0.6pF,保证信号带宽与眼图完整性。
  • 瞬态能量处理:8/20μs,250W 峰值。

五、封装与引脚

  • SOD-323 小封装,适用于 PCB 贴片装配。
  • 建议将器件尽量靠近需要保护的连接器或器件放置,缩短走线与回路面积以提高 ESD 耐受性。
  • 对于双向器件,两端对称连接至信号与地(或两线间),布局时保证可靠接地路径。

六、使用注意事项与选型建议

  • 对高速接口选择低电容 TVS(0.6pF)可最小化对信号完整性的影响;在差分线应保证匹配与对称布局。
  • 若系统有较高的静态电压或特殊浪涌要求,建议结合系统级滤波、电阻或共模滤波器共同防护。
  • 注意钳位电压与被保护器件的耐压要求,确保在浪涌工况下不会超过下游器件极限。
  • 在高温或多次冲击工况下关注可靠性与寿命,必要时进行系统级验证。

七、典型保护电路参考

常见接法:将 GBLC05CI-LF-T7 的两个端子并联于待保护信号线与地(针对单端)或并联于差分对两端(针对差分/双向),器件应靠近连接器端放置,并提供低阻抗接地回路。配合串联阻抗或共模滤波器使用,可进一步提高系统抗扰度与对后级器件的保护效果。

总结:GBLC05CI-LF-T7 以其超低结电容、5V 级工作电压匹配、250W 的瞬态处理能力及小型 SOD-323 封装,成为移动终端与高速数据信号线防护的实用选择。若需更详细的浪涌曲线、封装尺寸或应用示例图,请参考厂商数据手册或联系供应商技术支持。

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
