GBLC03C 瞬态抑制二极管（ESD 保护）产品概述
一、产品简介
GBLC03C 是东沃（DOWO）推出的一款单路单向瞬态抑制二极管（TVS），专为保护 3.3V 供电和高速信号线路免受静电放电（ESD）、电快速瞬变（EFT）及浪涌冲击而设计。器件采用 SOD-323 小封装，体积小、响应快，适合集成到空间受限的消费电子与工业接口电路中。
二、主要电气参数
- 工作电压 VRWM：3.3V
- 击穿电压 VBR(min)：4V
- 钳位电压 VC：19V（瞬态钳位）
- 峰值脉冲电流 Ipp：20A
- 峰值脉冲功率 Ppp：350W（在规定脉冲测试条件下）
- 反向电流 Ir：≤1 μA（常温）
- 结电容 Cj：约 1 pF（适合高速数据线）
- 通道数：单路，单向类型
- 工作温度：-55 ℃ ~ +150 ℃
三、主要特性
- 专为 3.3V 系统优化的钳位特性，能在高能瞬变时将电压限制在安全范围内；
- 超低结电容（≈1 pF），对高速信号干扰小，适合 USB、HDMI、LVDS、MIPI 等接口保护；
- 低反向漏电（1 μA），对低功耗系统影响小；
- 小封装 SOD-323，便于表面贴装与自动化生产；
- 满足 IEC 61000-4-2（ESD）、IEC 61000-4-4（EFT）及 IEC 61000-4-5（浪涌）等电磁兼容测试要求。
四、典型应用
- 3.3V 电源轨保护与去耦；
- 接口保护：以太网 PHY 外围、USB/HDMI/DisplayPort 等高速数据端口；
- 工业通讯接口、传感器输入、无线模块天线端口前端保护；
- 便携式设备、消费类电子及工业控制终端的输入输出保护。
五、封装与机械特性
- 封装：SOD-323（小型贴片封装），适配自动贴装与回流焊工艺；
- 封装适合空间受限的 PCB 布局，并便于并联或并排布置以增强保护能力。
六、应用与布板建议
- TVS 尽量靠近被保护接口或连接器放置，短而粗的输入引线以降低感抗；
- TVS 的接地焊盘应通过宽铜箔和多过孔连接至系统地，确保快速回流并散热；
- 对于高速差分线，选择单向 TVS 时注意方向与信号极性匹配；
- 在高能脉冲应用中，考虑器件热耗散及周边器件的耐压协调。
七、可靠性与合规
GBLC03C 在设计与测试上覆盖常见工业与消费级瞬态标准，适合在-55 ℃到 +150 ℃温度范围内长期工作。实际系统设计时建议参考厂商完整测试条件与浪涌曲线，以确保在目标脉冲波形下的可靠保护能力。
八、订购信息与使用注意
品牌：DOWO（东沃）；型号：GBLC03C；封装：SOD-323；类型：单路单向 TVS（ESD 保护）。在选型与采购时，请确认样片测试、封装版本与批次一致；贴片与回流焊时遵循封装的温度曲线与储存防潮规定。系统工程师应结合 PCB 结构、接地方案与实际能量级别，对保护方案进行完整验证。

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.
