P6KE400A(DOWO/东沃)产品概述

一、产品简介

P6KE400A 为单向高能瞬态电压抑制二极管(TVS),由玻璃钝化芯片制成,封装为 DO-15 轴向引脚,适用于高压直流或需要单向钳位的保护场合。该型号在 10/1000μs 波形下具备 600W 峰值脉冲功率能力(占空比 0.01%),响应极快、泄漏电流低,符合 RoHS 要求。

二、主要电气参数

  • 极性:单向
  • 反向工作电压 Vrwm:342V
  • 击穿电压 VBR:约 380V(标称)
  • 钳位电压 Vc(Ipp):548V(在 Ipp=1.09A 时)
  • 峰值脉冲电流 Ipp:1.09A(对应 10/1000μs)
  • 峰值脉冲功率 Ppp:600W(10/1000μs,0.01% 占空比)
  • 反向静态电流 Ir:1μA(典型)
  • 工作温度范围:-55℃ ~ +150℃

三、特性亮点

  • 玻璃钝化芯片,稳定性和长期可靠性好;
  • 极低的反向泄漏电流,适合高阻抗、低噪声应用;
  • 极快响应时间,能在瞬态开始阶段导通,保护下游器件;
  • 出色的钳位能力,在规定脉冲下将过压限制在安全范围内;
  • 支持单向和双向单元(本型号为单向);
  • DO-15 轴向封装,便于通孔安装与散热。

四、典型应用场景

  • 高压直流供电保护(DC 总线、逆变器、光伏逆变器前端保护);
  • 工业控制与驱动电路的浪涌吸收;
  • 通讯设备高压回路保护;
  • 电源模块、变换器输入端过压保护;
  • 需要高能量瞬态吸收且工作电压较高的场合。

五、选型与使用建议

  • 确保 Vrwm(342V)≥ 系统最大工作电压,避免常态下进入击穿区;
  • 若用于交流或双向浪涌保护,优先考虑对应的双向型号;
  • 检查脉冲能量与实际浪涌波形(10/1000μs)是否匹配,若浪涌能量更大需选更高 Ppp 或并联多只(并联时注意均流);
  • 高温或长期工作时关注器件结温,合理设计散热与间距;
  • 焊接和安装遵循厂家工艺说明,避免超温或过长焊接时间以保护玻璃钝化层与封装完整性。

六、封装与可靠性

DO-15 轴向封装便于通孔焊接和替换,机械强度好,适配传统手工或波峰焊工艺。玻璃钝化芯片提高了耐湿热与长期稳定性,工作温度覆盖 -55℃ 至 +150℃,适合工业级环境。请参照 DOWO(东沃)提供的完整机械图和焊接曲线以保证可靠性。

七、采购与合规

品牌:DOWO(东沃)。该系列符合 RoHS 要求,适合需要环保认证的产品。选型时注意索取完整数据手册与原厂样片,确认具体批次的典型参数和测试条件,以便在实际设计中留有充分裕度。

总结:P6KE400A(DO-15)为高压单向 TVS 器件,凭借 600W 峰值能力、低泄漏和快速响应,适合工业、通信及电力电子等需要高能瞬态保护的场合。在应用中请以 Vrwm 与脉冲能量匹配为首要选型原则,并结合散热与安装工艺保证可靠性。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Replenishment inquiry Typical RFQ workflow
