P6KE24CA瞬态抑制二极管(TVS)产品概述

P6KE24CA是一款双向瞬态抑制二极管(TVS),由东沃(DOWO)公司推出,采用DO-204AC(DO-15)轴向引线封装,专为24V级电路的瞬态过压保护设计,可有效抑制雷击、静电放电(ESD)、开关浪涌等瞬态干扰,保护敏感电子元器件免受损坏。

一、产品核心定位与类型属性

P6KE24CA属于轴向引线型TVS器件,双向极性设计使其无需区分正负极即可安装,简化了电路设计与生产流程。作为瞬态保护器件,其核心作用是当电路出现瞬态过压时,快速由高阻态转为低阻态,将过压钳位至安全范围,泄放瞬态电流,从而保护后端电路(如IC、传感器、电源模块等)。

二、关键电气参数及实际意义

P6KE24CA的电气参数针对24V系统优化,关键参数如下:

1. 反向截止电压(Vrwm):20.5V

该参数是器件正常工作时允许的最大反向电压,适配24V系统的常规工作电压范围(多数24V系统的正常工作电压波动在18~24V之间),确保器件在系统正常运行时处于截止状态,不影响电路功能。

2. 击穿电压(Vbr):22.8V

击穿电压是器件开始导通的电压阈值,当瞬态过压超过22.8V时,器件快速导通(响应时间纳秒级),可瞬间抑制过压上升,避免后端电路被过压击穿。

3. 钳位电压(Vc):33.2V

钳位电压是峰值脉冲电流下器件两端的最大电压,是保护后端电路的核心指标。例如,若后端IC的最大耐压为30V,33.2V的钳位电压可将过压峰值限制在IC可承受的安全范围内(考虑少量余量),避免IC损坏。

4. 峰值脉冲参数:600W@10/1000μs、18.07A

  • 峰值脉冲功率(Ppp):600W(对应10/1000μs脉冲波形,即上升沿10μs、半峰值时间1000μs的标准浪涌波形),表示器件可承受的最大瞬态功率;
  • 峰值脉冲电流(Ipp):18.07A,是600W功率下的峰值电流,可有效泄放开关浪涌、雷击等产生的大电流干扰。

5. 反向漏电流(Ir):1μA(典型值)

反向截止时的漏电流仅1μA,说明器件截止特性优异,正常工作时几乎不消耗电流,对系统功耗影响极小。

三、封装与环境适应性

P6KE24CA采用DO-204AC(DO-15)轴向引线封装,具有以下特点:

  • 体积小巧(直径约2.5mm,长度约5.2mm),适合插件式安装,可适配紧凑的电路板布局;
  • 工作温度范围宽:-55℃~+150℃,可适应工业环境(如高温车间、户外设备)、汽车电子(发动机舱附近)等严苛温度场景。

四、典型应用场景

P6KE24CA的参数适配性使其可广泛应用于以下场景:

  1. 工业控制电路:24V电源模块、PLC输入输出端口的过压保护;
  2. 汽车电子:车载传感器(如温度、压力传感器)、低压ECU辅助电路的浪涌抑制;
  3. 通信设备:以太网接口、电源端口的瞬态干扰防护;
  4. 消费电子:部分24V适配器输出端、智能家居设备的电源保护。

五、品牌与可靠性说明

东沃(DOWO)作为专业的保护器件厂商,P6KE24CA经过严格的可靠性测试(如温度循环、湿度测试、脉冲寿命测试等),参数一致性好,可满足批量生产的稳定性要求,是替代进口同类器件的高性价比选择。

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.

Replenishment inquiry Typical RFQ workflow
