P4KE6.8CA双向瞬态抑制二极管(TVS)产品概述

P4KE6.8CA是一款双向瞬态抑制二极管(TVS),由DOWO(东沃)品牌推出,专为低电压电路的瞬态过压防护设计,凭借紧凑封装与可靠的脉冲耐受能力,广泛适用于消费电子、工业控制等场景。

一、产品定位与基础属性

作为小功率TVS器件,P4KE6.8CA核心定位是低成本、高可靠性的瞬态过压防护,可替代同类规格产品(如P4KE6.8CA系列)。其基础属性清晰:

  • 极性:双向导通(无需区分正负极,安装更灵活);
  • 封装:DO-204AL(即DO-41轴向引线封装),体积小巧(轴向插件式,适配常规PCB设计);
  • 品牌:DOWO(东沃),专注防护器件研发,符合国内电子行业标准。

二、核心电气参数详解

参数是TVS性能的核心,P4KE6.8CA的关键参数针对性强,适配低电压场景:

1. 截止与击穿电压

  • 反向截止电压(Vrwm):5.8V:正常工作时,反向可承受的最大直流电压(不导通,无明显漏电流),适配3.3V、5V等常见低电压系统;
  • 击穿电压:6.46V:当反向电压超过此值时,器件快速击穿导通(瞬态过压触发),是TVS“启动防护”的关键阈值(通常比截止电压高10%~15%,避免误触发)。

2. 钳位与脉冲耐受能力

  • 钳位电压:10.5V:瞬态过压时,器件能将电压“钳制”在10.5V以内,保护后级敏感元件(如MCU、传感器)不被击穿;
  • 峰值脉冲电流(Ipp):38.1A:单次瞬态脉冲的最大耐受电流(10/1000μs波形下);
  • 峰值脉冲功率(Ppp):400W:对应10/1000μs脉冲波形(前沿10μs、半宽1000μs)的最大耐受功率,满足日常浪涌(如雷击、静电放电)的防护需求。

3. 环境适应性

  • 工作温度:-55℃~+150℃:宽温范围覆盖工业级(-40+85)、部分汽车级(-40+125)场景,可在高温环境(如汽车发动机舱附近)稳定工作。

三、封装与安装优势

P4KE6.8CA采用DO-204AL轴向封装,具备以下安装优势:

  1. 体积小巧:直径约2.7mm,长度约6.4mm,不占用PCB过多空间,适合小型化产品(如智能手环、小型传感器模块);
  2. 插件式安装:轴向引线设计,适配常规插件焊接工艺,无需特殊贴装设备,降低生产难度;
  3. 机械可靠性:封装外壳采用耐高温塑料,引线为镀锡铜线,抗振动、抗冲击能力符合工业级要求。

四、典型应用场景

由于适配低电压系统,P4KE6.8CA广泛应用于以下领域:

  1. 消费电子:手机充电口、USB接口、笔记本电脑IO端口的过压防护(防止静电、电源浪涌损坏主板);
  2. 工业控制:PLC输入输出模块、传感器节点(如温度、压力传感器)的防护(工业环境中易出现浪涌);
  3. 汽车电子:12V低压系统中的辅助控制器、车身传感器(如胎压监测模块)防护(宽温范围适配汽车工况);
  4. 通信设备:小型基站模块、无线AP的电源与信号端口防护(防止雷击浪涌)。

五、品质与可靠性保障

DOWO(东沃)对P4KE6.8CA的品质管控严格:

  • 符合GB/T 14590-2014《瞬态抑制二极管 总规范》等国内标准;
  • 经过脉冲寿命测试(多次施加额定脉冲仍保持性能)、温度循环测试(-55~+150℃循环500次无失效);
  • 批量一致性好,适合大规模量产应用,降低产品售后风险。

总结:P4KE6.8CA是一款性价比高、适配低电压场景的双向TVS,凭借双向导通、宽温耐受、紧凑封装等优势,成为消费电子、工业控制等领域过压防护的优选器件。

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
