Brightking BK23000702 轴向引线放电管产品概述

一、核心性能参数总览

BK23000702是台湾君耀(Brightking)推出的轴向引线陶瓷放电管,核心参数聚焦过压保护的关键指标,适配中低压场景的浪涌防护需求,具体如下:

  • 击穿电压:140V(精度±30%),属于工业级常见保护阈值,适配12V/24V供电设备;
  • 绝缘电阻:100MΩ(标准测试条件下),满足基本电气绝缘要求,无明显漏电流;
  • 电容值:0.8pF(低电容特性),对高频信号传输干扰极小;
  • 浪涌耐受能力:1kA(峰值电流,典型8/20μs波形),可抑制单次雷击或电源浪涌;
  • 工作温度范围:-40℃~+85℃,覆盖工业与户外应用的环境温度区间;
  • 封装形式:轴向DIP封装,兼容传统通孔焊接工艺。

二、关键特性与应用价值

1. 低电容适配高频场景

0.8pF的小电容是该器件的核心优势——在射频通信、高速数据传输线路中,若并联电容过大,会导致信号反射、衰减或相位偏移。BK23000702的低电容特性使其可直接并联于ADSL、光纤收发器、无线AP等设备的信号端口,无需额外设计信号隔离电路,简化防护方案。

2. 宽温稳定可靠

-40℃~+85℃的工作温度范围,满足户外安防(如室外摄像头)、工业控制(如PLC传感器接口)等场景的环境要求。即使在低温严寒或高温暴晒下,器件击穿电压漂移控制在行业标准内,避免温度变化导致的保护失效或误触发。

3. 轴向封装易集成

轴向引线DIP封装适配传统PCB通孔焊接,安装工艺成熟,无需特殊贴装设备,适合批量生产。引脚机械强度适中,可耐受常规焊接应力,同时便于手工焊接调试,降低中小批量应用成本。

4. 浪涌防护匹配主流需求

1kA的峰值浪涌电流(8/20μs波形)覆盖多数民用与工业场景的浪涌冲击——例如家庭宽带设备雷击防护、小型工业设备电源端口防护,若需更高等级,可配合TVS管级联使用。

三、典型应用场景

1. 通信设备信号端口防护

  • 光纤收发器、ADSL调制解调器的RJ45/RJ11接口;
  • 无线基站1GHz以下射频信号输入端口(低电容不影响传输)。

2. 户外安防监控系统

  • 室外摄像头的电源与视频信号接口(宽温适应-20℃~+60℃户外环境);
  • 门禁读卡器接口(抑制雷电感应浪涌)。

3. 工业控制设备防护

  • PLC数字量输入输出端口;
  • 温度/压力传感器信号传输线(避免工业现场电磁干扰浪涌)。

4. 消费电子辅助防护

  • 智能家居网关网络接口;
  • 小型充电器输出端口(抑制静电放电与电源尖峰)。

四、安装与注意事项

  1. 焊接要求:手工焊接温度≤350℃,时间≤3秒;回流焊峰值温度≤260℃;
  2. 引脚处理:弯曲半径≥引脚直径2倍,避免内部电极断裂;
  3. 并联安装:需与被保护线路并联(一端接信号/电源,一端接地),确保浪涌快速泄放;
  4. 降额使用:实际工作电压≤击穿电压的80%(即≤112V),避免长期老化。

五、品牌与可靠性保障

Brightking(台湾君耀)专注过压保护器件研发20余年,产品通过UL、VDE等国际认证,广泛应用于通信、汽车、工业领域。BK23000702采用陶瓷封装与稳定气体放电技术,长期使用性能一致性高,适合对可靠性要求较高的批量应用。

该器件以“低电容+宽温+易安装”为核心优势,是中低压场景浪涌防护的经济高效选择。

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
