Brightking BK22001502 轴向引线放电管产品概述

BK22001502是台湾君耀(Brightking)推出的一款轴向引线封装放电管,核心用于电路过压防护,可有效抑制雷电浪涌、静电放电及电源异常过压对敏感电子元器件的损害。该产品凭借稳定的电气性能、紧凑的封装设计,适配通信、工业控制、消费电子等多领域的电路防护场景。

一、品牌与产品定位

Brightking(君耀)作为专注过压保护器件的专业厂商,其放电管系列以高可靠性、宽电压覆盖、低电容特性著称。BK22001502属于该品牌常规轴向引线放电管,定位为中低压电路基础防护器件,针对需兼顾高频信号传输与浪涌防护的场景优化设计,适合传统电路布局的集成需求。

二、核心电气参数详解

BK22001502的关键参数直接决定防护能力与适用范围,具体如下:

  1. 击穿电压:标称300V,为电路提供明确过压动作阈值——正常工作电压下不导通,过压时快速击穿导通,泄放浪涌能量;
  2. 绝缘电阻:100MΩ(25℃环境下),高绝缘性能保证正常工作时漏电流极小,不影响电路信号传输与电源效率;
  3. 电容值:0.8pF(低电容特性),适配高频电路(如射频、数据线)防护,不会对信号完整性造成明显衰减;
  4. 浪涌电流能力:1kA(8/20μs标准浪涌波形下峰值电流),可承受单次/多次雷电浪涌、电源浪涌冲击,有效保护后端敏感器件;
  5. 封装形式:轴向引线直插(DIP),镀锡铜线引脚便于通孔焊接与电路集成。

三、封装与物理特性

BK22001502采用轴向引线小型化封装,核心物理特性如下:

  • 封装尺寸:直径约2.2mm,长度约6mm(含引脚,具体以厂商 datasheet 为准);
  • 引脚特性:直径约0.5mm,长度约10mm,可按需裁剪,焊接兼容性强;
  • 外壳材质:陶瓷封装,耐高温(-40℃~+85℃)、耐腐蚀,适应工业环境温湿度变化。

四、典型应用领域

结合参数特性,BK22001502适用于以下场景:

  1. 通信设备:固定电话、调制解调器、光纤收发器的电源/信号线路防护,抑制雷电浪涌对通信芯片的损害;
  2. 工业控制:PLC、传感器、变频器的电源过压防护,避免工业现场浪涌干扰;
  3. 消费电子:机顶盒、路由器、智能家居设备的电源/数据接口防护,应对市电波动与静电放电;
  4. 安防监控:监控摄像头、硬盘录像机的电源/视频信号线防护,提升户外环境防雷能力;
  5. 低压电源:12V/24V低压电源系统的过压保护,防止电源异常升高损坏负载。

五、使用注意事项

为确保防护效果与可靠性,使用时需注意:

  1. 并联安装:需并联在被保护电路两端(电源端与地、信号端与地),不可串联;
  2. 电压匹配:电路正常工作电压需低于击穿电压的70%(即210V以下),避免误动作;
  3. 焊接要求:焊接温度≤260℃,焊接时间≤5秒,防止过热损坏内部结构;
  4. 多级防护:建议配合保险丝、TVS管组成多级防护——放电管泄放大能量浪涌,TVS管快速响应小能量瞬态过压;
  5. 环境适配:避免在极端高温、高湿环境下长期使用,工作温度范围为-40℃~+85℃。

BK22001502作为高性价比轴向引线放电管,在中低压电路防护中具有广泛应用价值,其低电容、高浪涌能力的特性满足多数电子设备的过压防护需求。

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
