GBLC03C-N 产品概述

一、产品简介

GBLC03C-N 是伯恩半导体(BORN)推出的一款单路、双向 ESD 保护二极管,采用紧凑的 SOD-323 封装,专为对高速信号线和低电压接口提供瞬态过压保护而设计。器件通过 IEC 61000-4-2 等级测试,具备优良的抗静电放电能力与快速钳位响应,适用于消费电子、通信设备和工业控制等需要高可靠性保护的场景。

二、主要参数一览

  • 类型:ESD 保护器件(双向)
  • 工作电压 Vrwm(反向截止电压):3.3 V(适配 3.3V 系统)
  • 击穿电压 Vbr:7.8 V(典型)
  • 钳位电压 Vcl:17 V(典型)
  • 峰值脉冲功率 Ppp:230 W @ 8/20 μs
  • 峰值脉冲电流 Ipp:14 A
  • 反向漏电流 Ir:200 nA(在 Vrwm 条件下为典型量级)
  • 结电容 Cj:1.4 pF(低电容,适合高速信号)
  • 通道数:单路(单通道)
  • 极性:双向(对正负极方向均能进行钳位)
  • 防护等级/标准:符合 IEC 61000-4-2 测试要求(产品测试显示空气放电可达 30 kA 的抗扰能力记录)
  • 封装:SOD-323(小型表面贴装)

三、关键特性与优势

  • 适配 3.3V 逻辑:Vrwm = 3.3 V,专为 3.3V 电源域与信号接口保护优化,避免在正常工作条件下触发。
  • 双向保护:在双向 ESD 事件(正/负极)下均能快速响应,保护差分或单端信号线。
  • 低结电容:1.4 pF 的低寄生电容对高速信号影响小,可用于高速数据线、时钟线等对带宽敏感的接口。
  • 高能量吸收:230 W@8/20 μs 和 14 A 峰值电流能力,能吸收常见 ESD、脉冲浪涌的高能量瞬态。
  • 小型化封装:SOD-323 有利于高密度 PCB 布局,适合紧凑型设备和便携终端。

四、典型应用场景

  • 3.3V 数字接口保护(GPIO、UART、SPI、I2C 等)
  • 移动设备与便携式终端的外部连接器防护(耳机插孔、按键、显示接口等)
  • 工业控制与测量设备的 I/O 端口保护
  • 网络与通信设备的信号线防护(对低速或中速差分信号线尤为适用)
  • 任何需要兼顾低电容与高抗 ESD 能力的场合

五、封装与机械信息

GBLC03C-N 使用 SOD-323 小型封装,适合自动化贴装和回流焊工艺。由于封装体积小,安装时需注意焊盘设计和回流参数,以保证焊点可靠性与热量分散。建议结合厂商提供的封装图纸和推荐 PCB 尺寸进行设计。

六、PCB 布局与使用建议

  • 放置位置:将器件尽可能靠近被保护的连接器或信号入口,减小未保护段的走线长度与环路面积。
  • 地线连接:对于单端保护,确保接地层或回流路径低阻可靠,采用多盲/过孔将器件地快速接入参考地。
  • 布线要求:保护器件到被保护信号之间用最短走线,避免在保护器与信号之间并联大电容或长走线。
  • 热管理:虽然 SOD-323 为被动器件,但在发生大能量脉冲时会产生热量,建议在 PCB 设计时预留散热路径并避免与热敏元件紧邻。
  • 串联阻抗:在某些应用中可配合小阻值串联电阻以吸收部分能量,降低钳位电压峰值对后端电路的冲击。

七、使用注意事项

  • 工作电压匹配:Vrwm 为 3.3 V,若用于更高电压系统(例如 5 V),需评估器件在正常电压下的漏电与稳定性,或选择更高 Vrwm 的型号。
  • 热稳定性与重复击穿:长时间或重复遭受高能脉冲可能影响器件寿命,应在系统级进行抗冲击能力评估。
  • 合规测试:产品在设计导入前,建议做系统级的 IEC 61000-4-2 / 4-4 / 4-5 等电磁兼容测试,验证整个产品在实际工作环境下的抗扰性能。

GBLC03C-N 以其低电容、双向保护与小型封装特点,特别适合对 3.3V 低压、高速信号线进行高效的 ESD 保护,是便携式电子、通信与工业终端等产品的理想选择。对于具体样片、封装图及更详细的电气曲线,请联系供应商或查阅伯恩半导体提供的器件数据手册。

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
