GBLC15C-N 产品概述

一、产品简介

GBLC15C-N 是伯恩半导体(BORN)推出的一款小型单路单向瞬态电压抑制器(TVS/ESD),专为静电放电(ESD)与浪涌(Surge/EFT)保护设计。器件采用 SOD-323 封装,体积小、引脚少,适合贴片安装,能在有限的 PCB 空间内对敏感电路提供可靠防护。其设计兼顾高能量吸收能力与极低结电容,适合对信号完整性要求较高的接口保护。

二、主要参数与电气特性

  • 保护类型:ESD / TVS(单路、单向)
  • 反向工作电压 Vrwm:15 V(反向截止电压)
  • 击穿电压 Vbr(典型):16.7 V
  • 钳位电压 Vc(@ Ipp):40 V(在 8/20 μs 波形下)
  • 峰值脉冲功率 Ppp:240 W @ 8/20 μs
  • 峰值脉冲电流 Ipp:6 A(与 Vc 40 V 对应)
  • 反向漏电流 Ir:典型 1 μA(在 Vrwm 条件下)
  • 结电容 Cj:约 1 pF(适合高速信号线)
  • 防护等级 / 标准:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)
  • 封装:SOD-323,表面贴装

说明:在标准 8/20 μs 浪涌波形下,器件能承受 6 A 峰值脉冲并将钳位电压控制在约 40 V,从而实现对下游电路的有效保护。

三、典型应用场景

  • USB、串口、I2C、SPI 等接口的防静电保护(对高速信号友好,低 Cj 有利于信号完整性)
  • 车载和工业系统中 12 V 级电源或控制线的浪涌/ESD 保护(Vrwm=15 V 适配 12 V 系统边界)
  • 消费电子设备的外部连接器(耳机、充电口)与前端防护
  • 通信设备、传感器接口和模块化板卡的局部浪涌防护

四、封装与 PCB 布局建议

  • 尽量将 GBLC15C-N 放置在需保护的连接器或信号源与 PCB 入口附近,减小保护点与被保护线之间的走线长度。
  • TVS 的接地端应有低阻抗回路,建议使用接地平面并尽量缩短接地走线与过孔数量,以提高吸收脉冲的能力。
  • 对于高速差分信号,应留意器件对阻抗的影响,1 pF 的低结电容有助于保持信号完整性,但仍应在布局时做信号完整性验证。
  • SOD-323 小封装热阻相对较大,在面对高重复脉冲或较高能量应用时注意热量累积,必要时采用散热铜箔或增加散热面积。

五、选型与使用注意事项

  • 确定 Vrwm(反向工作电压)与系统工作电压匹配,GBLC15C-N 的 Vrwm=15 V 适用于不超过 15 V 的工作电压环境,若长期直流承受接近 Vrwm 的电压会增加漏电与功耗,需评估余量。
  • 钳位电压 40 V 在 6 A 浪涌情况下能有效保护大多数器件,但对极为敏感的低压芯片仍可能超出耐受值,必要时可并联更低钳位的保护器件或采取前级滤波限流措施。
  • 虽然器件符合多项 IEC 抗扰度标准,但实际 PCB 系统的抗扰性能还依赖接地、走线和连接器设计,建议在系统级进行实际抗扰度测试。
  • 作为防护元件,TVS 不是连续工作器件,长期承受频繁高能脉冲会降低可靠性,应根据应用场景评估使用寿命和备用保护方案。

GBLC15C-N 以其小型封装、低结电容和良好瞬态吸收能力,适合对空间和信号完整性有要求的接口防护,适用于消费电子、工业与车载等多类应用。

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
