P6KE100A 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心应用场景

P6KE100A是东沃(DOWO)推出的轴向直插式单向TVS管,属于P6KE系列(600W峰值功率级),核心定位为中等功率电路的瞬态过压防护器件,可有效抑制雷击浪涌、静电放电(ESD)、开关瞬态等突发过压,保护后端敏感电子元件(如IC、MOS管、电容等)。

其典型应用场景包括:

  • 工业控制:PLC输入输出模块、伺服驱动器电源端;
  • 通信设备:基站RRU电源、路由器DC-DC转换模块;
  • 汽车电子:车载充电器、车身控制单元(BCM)电源回路;
  • 消费电子:大功率LED驱动电源、户外监控设备电源。

二、关键电气参数深度解析

TVS管的核心性能由电气参数决定,P6KE100A的关键参数(典型值)及意义如下:

1. 防护方向与基础电压参数

  • 极性:单向:仅对单方向过压(如电源正极→地)有效,适合直流电路或单极性脉冲防护;
  • 反向截止电压(Vrwm):85.5V:器件正常工作时可承受的最大反向直流电压,若电路正常电压≤80V,该参数可匹配;
  • 击穿电压(Vbr):105V:过压达到该值时,器件快速导通(纳秒级响应),将电压钳位至更低值,避免后端器件损坏。

2. 过压防护核心指标

  • 钳位电压(Vc):137V:10/1000μs脉冲波形下的最大钳位电压,是防护的关键——需确保Vc≤后端器件最大耐压(如IC耐压150V则可匹配);
  • 峰值脉冲功率(Ppp):600W@10/1000μs:器件可承受的单次浪涌功率(10μs前沿+1000μs半峰值波形),代表中等浪涌容量;
  • 峰值脉冲电流(Ipp):4.38A@10/1000μs:浪涌时的最大导通电流,与Ppp匹配(137V×4.38A≈600W)。

3. 静态损耗参数

  • 反向漏电流(Ir):1μA@Vrwm:正常工作时漏电流极小,不影响电路功耗(长时间工作无明显发热)。

三、机械与环境适应性

1. 封装与安装特性

  • 封装类型:DO-15:轴向直插式封装,体积小巧(φ2.7mm×L5.1mm),适合传统通孔焊接工艺,安装便捷;
  • 引线设计:镀锡铜引线:抗氧化、焊接性好,可适配普通PCB板。

2. 宽温工作能力

  • 工作温度范围:-55℃~+150℃:覆盖工业级与汽车级温度要求,可在极端环境(如北方低温、工业高温区)稳定工作,无性能衰减。

四、选型与应用注意事项

1. 选型匹配原则

  • Vrwm需略高于电路正常电压:如电路正常电压75V,选85.5V(预留10%余量),避免误触发;
  • Vc需低于后端器件耐压:若后端IC最大耐压140V,137V钳位电压可满足需求;
  • 浪涌容量匹配:实际浪涌功率≤600W(10/1000μs波形)时适用,更大浪涌需升级1.5KE系列(1500W)。

2. 安装技巧

  • 靠近被保护电路:焊接在被保护元件(如IC)附近,引线长度≤5mm,减少寄生电感对钳位效果的影响;
  • 极性确认:带色环的阴极接高压端(电源正极),阳极接低压端(地),极性接反会失去防护作用。

3. 典型电路应用

  • 电源端防护:并联在直流电源正极与地之间,抑制雷击浪涌;
  • 信号端防护:若信号电压≤85.5V,并联在信号线上抑制ESD。

总结

P6KE100A作为高性价比单向TVS管,凭借600W峰值功率、宽温范围、小体积DO-15封装等优势,可广泛应用于工业、通信、汽车等领域的中等功率电路过压防护,是替代进口同类产品的优质国产选择。

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.
