GBLC05C 产品概述

GBLC05C 是 DOWO(东沃)推出的一款低电容、双向瞬态电压抑制(TVS)二极管,采用 SOD‑323 小型封装,针对高速信号线与低电压供电系统的静电放电(ESD)与浪涌干扰提供有效保护。器件在保持极低结电容的同时,提供高冲击吸收能力与宽工作温度范围,适合移动设备、通信接口、传感器及工业控制等对信号完整性与抗干扰能力要求较高的场景。

一、主要参数一览

  • 型号:GBLC05C(品牌:DOWO/东沃)
  • 类型:双向、单路 TVS(ESD 保护)
  • 反向工作电压 VRWM:5 V
  • 击穿电压 VBR(Min):6 V
  • 钳位电压 VC:30 V(典型值,在规定脉冲条件下测得)
  • 峰值脉冲电流 Ipp:20 A(8/20 µs 波形)
  • 峰值脉冲功率 Ppp:300 W(8/20 µs 标准波形)
  • 反向漏电流 Ir:≤ 1 µA(在 VRWM 下)
  • 结电容 Cj:≈ 0.8 pF(低电容设计,利于高速信号)
  • 通道数:单路,双向抑制(双向对称行为)
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 防护等级/认证:满足 IEC 61000‑4‑2(ESD)、IEC 61000‑4‑4(EFT)
  • 封装:SOD‑323(小尺寸、表面贴装)

二、产品特点

  • 低结电容(约 0.8 pF):对高速差分信号、USB、HDMI、SATA 等接口的影响最小,保证信号完整性。
  • 双向结构:可在正负极性瞬变下均能工作,适用于数据线、交流信号或未定义极性场合。
  • 高冲击吸收能力:单次 8/20 µs 脉冲下可承受 300 W 峰值功率及 20 A 峰值电流,有效钳制瞬态电压峰值。
  • 小型 SOD‑323 封装:占板面积小,便于自动贴装与大批量生产。
  • 宽温工作范围与可靠性认证:适应工业级应用环境,并满足常用的抗静电与抗脉冲标准。

三、典型应用场景

  • 移动终端与便携设备的 I/O 口(耳机、充电口、USB/OTG)保护。
  • 工业控制与传感器接口的浪涌与静电防护。
  • 通信设备的数据线与信号线(串口、I2C、SPI 等)保护。
  • 消费电子(电视机顶盒、机顶盒、路由器)与汽车电子的低压信号防护(在符合温度与可靠性要求的前提下)。
  • PCB 上靠近外部接入点的防护器件,与滤波器或阻尼元件配合使用以提高系统抗扰度。

四、设计与使用建议

  • 布局:将 GBLC05C 尽量靠近需保护的输入/输出引脚放置,最短的引线和最小回路面积可降低钳位电压上升与串联感性影响。
  • 串联阻抗:在需要额外钳制能力或防止瞬态回注的场合,可与小阻值串联电阻或共模电感配合使用。
  • 热与能量考虑:Ppp=300 W 为单次 8/20 µs 脉冲能力,连续或重复脉冲时需考虑能量累积和器件温升,必要时采用更高能量级器件或外部保护。
  • 极性注意:本器件为双向结构,可直接用于双向信号线;若系统为单向高精度保护,可选择单向型 TVS 以获得更低钳位电压效果。
  • 焊接与回流:遵循 SOD‑323 的回流焊工艺规范,避免过高温度和过长加热造成器件性能下降。

五、可靠性与包装

GBLC05C 满足常见的工业温度与耐受标准,经过 ESD 与脉冲冲击测试验证。产品提供适合集成电路装配的带装卷盘(reel)包装,便于 SMT 自动化贴装。存储与运输应防潮、防静电,遵守电子元器件一般存储规范(避免高湿、高温及长时间阳光直射)。

总结:GBLC05C 以其低电容、高能量吸收能力和小型封装,适合对信号完整性要求高且需要保护外部端口的电子系统。合理的 PCB 布局与配套防护策略能使其在实际应用中发挥最佳保护效果。若需更详细的电气曲线、典型钳位测试条件或封装引脚尺寸图,请告知以便提供数据手册或测试曲线。

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
