Brightking 680KD07-P5Z2C3Z2T3.4Z2 压敏电阻产品概述

一、产品基本信息

本产品为台湾君耀电子(Brightking) 推出的氧化锌压敏电阻,型号全称680KD07-P5Z2C3Z2T3.4Z2。采用径向引线封装,元件直径7mm,引脚间距(P)为5.0mm,体积紧凑,适用于空间受限的电路设计场景。作为瞬态过压防护核心元件,其主要作用是吸收电路中的浪涌电压,保护后端敏感电子元件免受雷击、静电放电(ESD)、开关浪涌等瞬态冲击损坏。

二、关键电气参数解析

电气参数是压敏电阻选型的核心依据,本产品关键参数如下:

2.1 电压类核心参数

  • 压敏电压(V₁ₘₐ):68V ±10%,即元件在1mA测试电流下的电压值,是产品电压等级的核心标识,公差±10%确保批量一致性;
  • 工作电压(额定电压):直流(DC)56V、交流(AC)40V,为元件可长期稳定工作的电压上限,选型时需确保电路正常工作电压不超过此值,避免元件老化失效;
  • 钳位电压(V꜀):135V(典型值),指元件耐受峰值浪涌电流250A时的最高电压,直接决定对后端元件的保护能力——浪涌发生时,元件将电压钳位在135V以内,防止敏感元件被击穿。

2.2 浪涌耐受能力

  • 峰值浪涌电流(Iₚₚ):250A,为元件可承受的单次最大瞬态电流峰值;
  • 能量耐受(E):3.6J,对应浪涌电流的能量吸收能力,需与电路中可能出现的浪涌能量匹配(如开关浪涌通常在1J以内,本产品可覆盖多数低压场景)。

2.3 辅助参考参数

  • 静态电容:740pF@1kHz,电容值与频率相关,高频电路中需注意其对信号完整性的影响;
  • 静态功率:20mW,为元件在无浪涌状态下的功耗,对电路整体功耗影响极小。

三、封装与物理特性

本产品采用径向双引线封装,具体物理特性如下:

  • 元件直径:7mm(圆盘状结构,便于安装);
  • 引脚间距(P):5.0mm(PCB焊接时的中心距,适配常规焊盘设计);
  • 引脚材质:镀锡铜(良好的焊接性,适配回流焊、波峰焊等常规工艺);
  • 工作温度范围:-40℃~+85℃(满足多数工业及消费电子场景的环境需求);
  • 存储温度范围:-55℃~+125℃(便于仓储运输,长期存储性能稳定)。

四、典型应用场景

结合参数特性,本产品适用于低压小功率电路的瞬态防护,典型应用包括:

  1. 消费电子:手机充电器、蓝牙耳机充电盒、小型家电控制板(如加湿器、台灯)的电源端口过压保护;
  2. 通信辅助电路:路由器、调制解调器、智能音箱的电源及信号接口浪涌防护;
  3. LED驱动电源:低压LED灯带、小功率LED灯具的驱动电路防护;
  4. 工业控制辅助电路:小型传感器、PLC模块的低压供电端口防护。

五、产品核心优势

  1. 浪涌防护匹配性强:峰值250A、能量3.6J的耐受能力,可覆盖日常低压电路中常见的浪涌冲击(如开关浪涌、静电放电);
  2. 电压参数清晰:压敏电压公差±10%、工作电压明确,选型时可精准匹配电路需求,避免超压风险;
  3. 封装紧凑灵活:7mm直径+5mm引脚距,适配高密度PCB设计,尤其适合小型化产品;
  4. 品牌可靠性:Brightking君耀为专业压敏电阻厂商,产品一致性好,符合RoHS环保要求及相关安规标准(如UL、VDE等,需结合具体认证版本)。

六、选型与使用注意事项

  1. 工作电压降额:电路长期工作电压需低于DC56V/AC40V,避免元件因持续工作在接近额定电压下加速老化;
  2. 浪涌能量匹配:单次浪涌能量不超过3.6J,多次冲击需按君耀产品手册的降额曲线使用;
  3. 高频电路优化:740pF的静态电容在10MHz以上电路中可能影响信号,可结合小电容并联或TVS管优化防护方案;
  4. 焊接工艺要求:焊接温度不超过260℃(回流焊),焊接时间不超过10秒(波峰焊),避免损伤元件内部结构。

本产品凭借紧凑封装、明确的电压参数及可靠的浪涌耐受能力,成为低压小功率电路瞬态防护的优选元件,可满足多数消费电子及工业辅助电路的防护需求。

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.
