Brightking P6KE22A/B 瞬态抑制二极管(TVS)产品概述

Brightking(台湾君耀)作为专业过压防护器件制造商,其P6KE22A/B系列瞬态抑制二极管(TVS)凭借稳定的电气性能、宽温适应性及可靠防护能力,广泛应用于工业、汽车、通信等领域的电路过压防护场景。

一、产品定位与核心功能

P6KE22A/B属于轴向引线式TVS器件,核心功能是快速吸收电路中的瞬态浪涌或静电放电(ESD)能量,将电路电压钳位在安全范围内,避免后端敏感电子元件(如MCU、传感器、通信芯片)因过压损坏。
其中,P6KE22A为单向TVS(仅反向击穿导通),适用于单极性电源/信号电路;P6KE22B为双向TVS(正反向均击穿导通),兼容交流电路或双向信号防护,用户可根据电路极性选型。

二、关键电气参数详解

该系列参数围绕“防护效率”与“电路兼容性”设计,核心参数如下:

1. 电压类参数

  • 反向截止电压(Vrwm):18.8V
    电路正常工作时反向偏置不导通,需略高于电路最大工作电压(如12V/15V系统),确保静态下不影响电路功能,同时预留瞬态过压防护裕量。
  • 击穿电压(Vbr):20.9V
    典型击穿阈值,电压超过该值时TVS快速从截止态转为导通态,启动防护;参数一致性好,避免击穿电压波动影响可靠性。
  • 钳位电压(Vc):30.6V
    8/20μs标准浪涌脉冲下的钳位值,需低于后端器件最大耐受电压(如汽车功率器件耐压35V以上),是防护有效性的核心指标。

2. 功率与电流参数

  • 峰值脉冲功率(Ppp):600W
    8/20μs浪涌脉冲下的额定功率,可吸收单次最大600W瞬态能量,满足工业/汽车场景(如汽车抛负载浪涌)需求。
  • 峰值脉冲电流(Ipp):19.9A
    对应Ppp的最大脉冲电流,反映器件浪涌承载能力,电压钳位至30.6V时可通过的最大瞬态电流。
  • 反向漏电流(Ir):1uA
    Vrwm下反向漏电流仅1μA,适合低功耗电路(如电池供电设备、传感器节点),避免静态功耗增加。

3. 防护等级与兼容性

符合IEC 61000-4-2标准,支持静电放电(ESD)防护,可应对接触放电(8kV)、空气放电(15kV)场景,满足电磁兼容(EMC)要求。

三、机械与环境特性

  • 封装形式:DO-15(DO-204AC)
    轴向引线封装,尺寸小巧(直径2.3mm,长度5.2mm),适合通孔焊接,兼容多数PCB设计;引脚为镀锡铜线,焊接可靠性高。
  • 工作温度范围:-55℃~+175℃
    宽温覆盖工业级(-40℃+85℃)与汽车级(-40℃+125℃)标准,可满足极端环境(如高温工业设备)需求。
  • 品牌可靠性:Brightking
    经严格可靠性测试(温度循环、湿度老化、脉冲寿命),品质稳定,可替代进口同类器件。

四、典型应用场景

P6KE22A/B适配多领域防护需求,典型应用包括:

  1. 汽车电子:车载CAN/LIN总线、ECU电源端口、传感器(压力/温度)的浪涌/ESD防护;
  2. 工业控制:PLC输入输出模块、工业传感器(编码器/流量计)接口、低压直流电源过压钳位;
  3. 通信设备:以太网端口、串口(RS485/RS232)、无线模块(WiFi/Bluetooth)的ESD防护;
  4. 电源系统:12V/24V直流电源适配器、电池充电电路的浪涌防护;
  5. 消费电子:充电器接口、音频/视频接口的静电防护(需匹配电路电压)。

五、选型与使用注意事项

  1. 极性匹配:单极性电路选A系列,双向电路选B系列;
  2. 电压裕量:Vrwm≥电路最大工作电压,Vc<后端器件最大耐受电压;
  3. 安装建议:焊接温度≤260℃(持续≤10s),避免引脚过热损伤;
  4. 存储要求:温度-55℃~+150℃,湿度≤85%RH,避免潮湿环境长期存储。

P6KE22A/B系列TVS以高性价比、宽温适应性及可靠防护性能,成为工业、汽车等领域过压防护的常用选型,有效提升电路抗干扰能力与可靠性。

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.
