P6KE200A 产品概述

一、产品简介

P6KE200A 是一款单向 TVS(瞬态电压抑制二极管)保护器件,采用玻璃钝化芯片工艺,封装为 DO-204AC(俗称 DO-15)直插封装,由 DOWO(东沃)品牌生产。该器件专为抑制瞬态过电压(如雷击、开关反冲等)设计,能在瞬时高能脉冲到来时快速钳位电压,保护下游电子元器件免受损坏。器件符合 RoHS 要求,适用于工业电源、通信设备、电源适配器、家电及一般电子设备的浪涌保护。

二、主要电气参数

  • 极性:单向(单向单元可防止反向电压冲击)
  • 反向工作电压 Vrwm(稳态):171 V
  • 击穿电压 VBR:190 V(典型指定区间)
  • 钳位电压(Ipp 条件下):274 V
  • 峰值脉冲电流 Ipp:2.19 A(在标准测试波形下)
  • 峰值脉冲功率能力:600 W(测试波形 10/1000 μs,重复率 0.01%)
  • 反向漏电流 Ir:1 μA(常温、在 Vrwm 条件下)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:DO-204AC (DO-15)
  • 特性:玻璃钝化芯片、低泄漏、响应极快、优良钳位能力
  • 环保:符合 RoHS 标准

三、性能亮点

  • 玻璃钝化芯片:提高长期可靠性和热稳定性,适合在较宽温度范围内长期工作。
  • 高脉冲能量承受能力:在 10/1000 μs 波形下可承受 600 W 峰值脉冲功率,能够应对强烈的浪涌事件。
  • 低漏电流:典型 1 μA 漏电流,适合对待机功耗敏感或高阻抗电路的保护。
  • 快速响应:在瞬态出现时能迅速进入钳位状态,保护下游器件免受过压瞬变影响。
  • 单向结构:适合直流电源线、偏置线路等需要方向性保护的场合。

四、典型应用场景

  • 工业电源和控制系统的输入端浪涌保护
  • 开关电源(SMPS)输出/输入的瞬态抑制
  • 电源适配器、UPS、逆变器等电源设备
  • 通信设备和接口线路的过压保护(如中低速串行线、信号线)
  • 家用电器、电动工具等受雷击或开关瞬态影响的产品

五、选型与使用建议

  • 工作电压匹配:选择 TVS 时应保证 Vrwm(171 V)高于正常工作电压,但留有安全裕量;若被保护电路工作电压接近或高于 Vrwm,应选用更高 Vrwm 等级的型号。
  • 钳位电压要求:钳位电压 274 V 为在标准脉冲条件下的典型值,需确保此电压对被保护元件为可接受的峰值电压。
  • 峰值能量考量:600 W(10/1000 μs)表示器件在该测试波形下的瞬态处理能力。对重复或长时间高能脉冲,应考虑外加限流元件(熔断器、PTC、串联电阻等)以保护 TVS 本体。
  • 安装布局:将 TVS 尽可能靠近被保护端口或电源入口,减小连接导线的寄生电感,以达到最佳抑制效果。
  • 热管理与可靠性:尽量避免长时间在高温环境下工作;在高脉冲环境中应考虑散热与器件热应力,必要时采用并联或外加保护器件分担能量。
  • 单向/双向选择:若被保护线路为交流或双向脉冲,应选用相应的双向型号;本型号为单向,适合直流或有明显极性的线路。

六、封装与机械信息

P6KE200A 采用 DO-204AC(DO-15)轴向玻璃钝化封装,适合插装焊接。该封装具有良好的机械强度与散热路径,便于维修和替换。封装形式利于通过孔(THT)安装在 PCB 边缘或引出端,常用于电源输入端的浪涌保护模块。

七、应用注意事项与可靠性提示

  • 对于频繁发生的大能量冲击场合,建议在电路中增加外部限流/熔断手段,避免 TVS 本体在多次高能冲击下退化。
  • 在高湿、高腐蚀环境中使用时,注意封装焊点的防护和 PCB 防护处理,延长器件寿命。
  • 若对漏电流极度敏感,应在不同温度条件下评估实际漏电特性(Ir 随温度上升可能增加)。
  • 在选型时综合考虑 Vrwm、VBR、Vclamp 与被保护设备耐压,保证在最坏瞬态下系统仍在安全边界内。

总结:P6KE200A(DOWO)是一款面向中高压瞬态保护的单向 TVS 器件,玻璃钝化工艺、600 W 峰值脉冲能力、低漏电及良好的钳位性能,使其成为工业电源、通信设备及一般电子设备中可靠的过压保护选择。购买与设计使用时,请按照具体应用的工作电压、钳位要求与能量等级作出合适配置。

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.
