Brightking P6KE39A/B 瞬态抑制二极管(TVS)产品概述

Brightking(台湾君耀)推出的P6KE39A/B是一款单向瞬态抑制二极管(TVS),属于P6KE系列小功率TVS产品,专为电子电路中的瞬态过压保护设计。凭借宽温范围、高瞬态功率承受能力及通用封装,广泛应用于工业控制、汽车电子、通信设备等场景,是电路过压防护的主流选型之一。

一、产品基本属性与核心定位

P6KE39A/B为单向TVS,仅对反向过压触发保护,核心作用是:当电路出现浪涌、静电放电(ESD)等瞬态高压时,快速从截止态转为雪崩导通,将电压钳位在安全范围,避免后端敏感器件(如MCU、传感器、通信芯片)被击穿损坏。

二、核心电气参数详解

参数针对瞬态保护需求优化,关键指标如下:

1. 电压类参数(保护阈值)

  • 反向截止电压(V₍RWM₎):33.3V
    电路正常工作时TVS反向截止的最大电压(漏电流极小),需匹配电路正常电压(建议电路最大工作电压≤V₍RWM₎),避免误触发。
  • 击穿电压(V₍BR₎):37.1V
    反向过压达到此值时,TVS启动雪崩导通(典型值,实际范围33.4V~40.8V,符合器件公差),开始保护。
  • 钳位电压(V₍C₎):53.9V
    峰值脉冲电流(I₍PP₎=11.3A)下的最大电压,是后端器件能承受的电压上限(需确保后端耐压≥V₍C₎)。

2. 电流与功率参数(瞬态承受能力)

  • 峰值脉冲功率(P₍PP₎):600W
    器件能承受的最大瞬态脉冲功率(持续时间8/20μs或10/1000μs),是浪涌保护能力的核心指标,覆盖多数中小功率电路需求。
  • 峰值脉冲电流(I₍PP₎):11.3A
    对应P₍PP₎=600W的峰值电流,反映高电流瞬态下的导通能力。
  • 反向漏电流(I₍R₎):1μA(@V₍RWM₎)
    正常工作时漏电流极小,对电路功耗影响可忽略,提升系统效率。

三、封装与工作环境特性

1. 封装形式:DO-15(轴向引线)

  • 尺寸小巧(直径≈2.5mm,长度≈5.5mm),引脚为镀锡铜引线,焊接方便;
  • 适合PCB通孔安装,适配紧凑电路设计(如车载传感器、小型通信模块)。

2. 工作温度范围:-55℃~+175℃

  • 覆盖工业级(-40℃+85℃)、汽车级(-40℃+125℃),甚至高温工业场景(如冶金设备);
  • 极端温度下仍保持稳定的电气性能,可靠性高。

四、典型应用场景

P6KE39A/B的参数特性适配以下场景:

  1. 汽车电子:车载传感器(压力、温度)、ECU电源/信号接口,防护点火浪涌、ESD;
  2. 工业控制:PLC、伺服驱动器I/O接口,应对雷击感应、电机启停干扰;
  3. 通信设备:路由器、交换机以太网/电源端口,防护ESD及通信浪涌;
  4. 消费电子:高端电源适配器、智能家电电源电路,提升抗干扰能力。

五、选型与使用注意事项

  1. 极性匹配:单向TVS需阴极(带色环端)接高电位,阳极接低电位,接反则保护失效;
  2. 参数裕量:
    • V₍RWM₎≥电路正常电压的1.2~1.5倍(如30V电路适配33.3V V₍RWM₎);
    • V₍C₎≤后端器件最大耐压(如60V芯片适配53.9V V₍C₎);
  3. 焊接要求:焊接温度≤260℃(持续≤10s),避免高温损坏;
  4. 并联扩容:需提升功率时,可并联多个同型号器件(极性一致),但需确保参数一致性。

总结

Brightking P6KE39A/B是一款高性价比单向TVS,凭借600W峰值功率、宽温范围及DO-15通用封装,成为工业、汽车、通信等领域过压保护的主流选型。其ns级快速响应、低漏电流特性,可有效防护瞬态干扰,保障电路可靠性。

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.
