GBLC05C AC SOD-323 产品概述

一、产品简介

GBLC05C AC(MDD,SOD-323 封装)是一款小尺寸双向ESD保护二极管,面向便携设备和高速信号线的静电放电与瞬态浪涌保护。其典型参数:反向截止电压 Vrwm = 5V,击穿电压 Vbr = 6V,钳位电压 Vc ≈ 18.3V,峰值脉冲电流 Ipp = 8A(8/20µs),峰值脉冲功率 Ppp = 300W(8/20µs),反向漏电 Ir = 1µA,结电容 Cj ≈ 1pF,工作温度 -55℃ ~ +150℃。器件通过 IEC 61000-4-2 与 IEC 61000-4-4 抗扰度验证,适合对敏感接口提供低电容、快速响应的保护。

二、主要特性

  • 极性:双向(对称钳位,适合差分或未定义极性的信号线)
  • 低电容:Cj ≈ 1pF,适合高速数据线(如 USB2.0、HDMI 较低速通道、差分对)
  • 高能量吸收:Ppp = 300W(8/20µs),Ipp = 8A,能够承受典型浪涌与人体模型静电事件
  • 低漏电:Ir = 1µA,有利于电池供电系统的待机功耗控制
  • 宽温度范围:-55℃ ~ +150℃,工业级可靠性

三、典型应用场景

  • 手机与平板的外部接口(USB、耳机、充电口)
  • 数据通信线路的输入/输出保护(串口、I2C、SPI、差分对)
  • 工业控制模块的端口浪涌与静电防护
  • 需要低电容且不影响信号完整性的高速接口保护

四、使用与布局建议

  • 器件应尽可能靠近外部连接器放置,以缩短受保护节点与接地返回路径;焊盘与走线应尽量短且直。
  • 对于双向器件,无需方向标注;两端对称连接到需要保护的信号线上,再将共同端直接接地。
  • 为减少寄生电感与提高放电能力,建议在器件到地的回流路径上使用多短且宽的铜箔和足够数量的过孔。
  • 由于 Cj 仅 ~1pF,可并联在高速信号线上而对信号完整性影响最小,但在差分敏感应用中仍需做信号仿真验证。

五、热与可靠性注意事项

  • 峰值脉冲能量基于 8/20µs 波形评定,长期或重复高能脉冲会降低器件寿命,应按系统级浪涌标准做整机验证并采用限流/熔断等保护手段。
  • 工作温度范围 -55℃ ~ +150℃,高温时漏电流会增加,设计时需考虑温漂与热耗散。
  • 建议参考完整数据手册中的热阻、焊接条件与可靠性试验结果进行可靠性评估。

六、选型与注意事项

  • 若保护对象为严格 5V 电源或信号线,Vrwm = 5V 与 Vbr = 6V 的配对适合在保护阈值与正常工作之间提供足够余量。
  • 当系统需要更低钳位电压或更高浪涌吸收能力时,考虑并联限流元件或选择更大 Ppp 等级的 TVS 器件。
  • 采购填写型号示例:GBLC05C AC,封装 SOD-323,品牌 MDD。建议在量产前向厂商索取完整数据手册与推荐 PCB 尺寸及回流焊工艺规范。

如需该器件的等效电路图、典型钳位曲线或推荐封装焊盘图,可进一步提供数据手册链接或要求,我可协助解析并给出具体布局参数与仿真建议。

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
