BTC102N 产品概述

一、产品简介

BTC102N 是 BORN(伯恩半导体)出品的一款表面贴装气体放电管(GDT),封装为常见的 1812(尺寸 4.5mm × 3.2mm × 2.7mm)。该器件为两端结构,专为电力浪涌和雷击等瞬态过电压提供高能量放电通道,用以保护通信设备、电源接口及其他敏感电子电路。

二、主要特性

  • 极数:2(双端/双极)
  • 直流击穿电压 Vdc:1 kV(典型)
  • 冲击击穿电压 Vimp:1.8 kV
  • 脉冲放电电流:1 kA(峰值,具体测试条件请参见厂方规范)
  • 极间电容:约 1 pF(对高速信号线影响小)
  • 精度(击穿电压公差):±30%
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:1812(SMD)

三、应用场景

适用于需要对高能瞬态浪涌实现直流/交流高压夹断与放电的场合,例如电话线与数据通信口防护、ADSL/FTTx 入口设备、配电箱接口、工业控制、安防摄像头电源入口等。由于极低的极间电容,也适合需要兼顾信号完整性的高速数据线路保护。

四、设计与选型建议

  • 放置位置:优先靠近线路入口或受保护设备的第一接触点,尽量缩短保护元件到被保护端的导线长度。
  • 配合使用:可与 TVS 二极管、熔断器或阻尼网络组成多级防护,TVS 负责低能量快速钳位,GDT 负责大能量放电。
  • 浪涌能力说明:标称 1 kA 脉冲放电电流为典型能力指标,具体能承受的能量和重复冲击寿命应参考厂方详细测试条件(如波形、持续时间)。
  • 焊接与可靠性:为保证可靠性,请遵循 BORN 官方的回流焊曲线与存储条件。放电后若出现异常击穿或参数漂移,应更换器件。

五、安装与维护要点

  • PCB 布局:GDT 两端焊盘尽量短而宽,减少串联电感与阻抗。
  • 机械应力:避免在回流或后续加工过程中对器件施加过大剪切力或弯曲力。
  • 替换策略:发生过大雷击或多次超过额定放电后,建议更换器件以确保保护性能。
  • 存储与防护:避免潮湿、高温环境,运输与装配过程中做好防静电与防机械冲击措施。

六、总结

BTC102N 为一款体积小巧、极间电容低、适合高速线路保护的 2 端气体放电管,直流击穿约 1 kV、冲击击穿 1.8 kV、峰值脉冲放电电流 1 kA,工作温度范围 -40 ℃ 至 +85 ℃。在需要面对中大能量浪涌场合时,可作为可靠的一级或二级过压防护元件选用。购买与使用时建议参照 BORN 提供的详细数据手册与焊接指南。

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.

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
