P6KE75CA 瞬态抑制二极管(TVS)产品概述

P6KE75CA是东沃(DOWO)品牌推出的双向瞬态抑制二极管(TVS),采用DO-204AC(DO-15)轴向直插封装,专为电路中的瞬态过压防护设计,可有效抑制静电放电(ESD)、浪涌脉冲等干扰,保护敏感电子元器件免受损坏。其宽温范围、中功率防护能力适配工业、通信、汽车等多场景需求。

一、产品核心定位与适用场景

该器件属于中功率TVS系列,针对低压直流电路、工业接口、通信链路等场景的瞬态防护需求优化:

  • 双向极性设计无需区分安装方向,简化电路设计与生产工艺;
  • 宽工作温度(-55℃~+150℃)适配工业级、汽车级 harsh 环境;
  • 600W脉冲功率(10/1000μs波形)可应对常见浪涌冲击,满足多数民用/工业设备防护要求。

二、关键电性能参数详解

1. 防护阈值与截止特性

  • 反向截止电压(Vrwm):64.1V
    电路正常工作时,器件处于截止状态的最大反向直流电压,需确保电路正常电压不超过此值(如24V/48V系统完全适配)。
  • 击穿电压(Vbr):71.25V
    反向电压超过此值时,器件开始导通,进入钳位工作模式,是防护启动的关键阈值(一致性良好,减少防护盲区)。

2. 脉冲防护能力

  • 峰值脉冲功率(Ppp):600W(10/1000μs波形)
    符合IEC 61000-4-5浪涌标准,“10/1000μs”指脉冲上升时间10μs、半值下降时间1000μs,可覆盖常见浪涌场景。
  • 峰值脉冲电流(Ipp):5.83A
    同波形下的最大允许峰值电流(由Ppp=Vc×Ipp计算:600W÷103V≈5.83A),体现器件瞬时电流承载能力。
  • 钳位电压(Vc):103V
    峰值脉冲电流下的最大电压降,是被保护器件的最终限制电压(需低于其耐压值,如IC耐压120V时可安全防护)。

3. 静态可靠性指标

  • 反向漏电流(Ir):1μA
    Vrwm下的反向漏电流极小,不影响电路正常工作,体现器件绝缘特性与长期稳定性。

三、封装与物理特性

采用DO-204AC(DO-15)轴向直插封装,是工业领域经典小功率封装形式:

  • 尺寸紧凑(典型直径2.5mm、长度10mm),适合插件焊接工艺,无需特殊夹具;
  • 镀锡铜引脚耐焊接温度(≤260℃/10s),焊接可靠性高;
  • 玻璃钝化硅片外壳,抗机械冲击与环境腐蚀能力强,适配户外/工业环境。

四、典型应用场景

  1. 工业控制电路:PLC输入输出接口、温度/压力传感器的浪涌防护;
  2. 通信设备:以太网、RS485/232串行接口、无线模块天线端的ESD与浪涌抑制;
  3. 低压电源系统:24V/48V直流电源输出端、电池管理系统(BMS)的过压保护;
  4. 汽车电子:车载中控、传感器辅助电路的瞬态防护(适配-55℃~+150℃宽温);
  5. 消费电子:机顶盒、路由器、智能家居设备的接口防护。

五、应用注意事项

  1. 并联安装:TVS需并联在被保护电路两端(双向无需区分正负极);
  2. 参数匹配:
    • Vrwm≥电路正常工作电压(如60V系统选64.1V适配);
    • Vc≤被保护器件最大耐压(如120V IC用103V Vc安全);
  3. 焊接规范:避免超过260℃/10s的焊接温度,防止热损伤;
  4. 脉冲限制:虽可承受数千次脉冲冲击,但需避免连续kHz级高重复率脉冲(防功率累积损坏)。

P6KE75CA以其平衡的防护能力、宽温特性与易用性,成为工业、通信等领域中低压电路瞬态防护的高性价比选择。

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
