P4KE15CA瞬态抑制二极管产品概述

P4KE15CA是东沃(DOWO)品牌推出的双向瞬态抑制二极管(TVS),专为15V级别电路的瞬态过压保护设计,凭借紧凑封装、宽温适应性及强脉冲耐受能力,广泛应用于通信、工业控制、消费电子等领域。

一、产品核心定位与核心功能

作为P4KE系列中的15V级别型号,P4KE15CA的核心功能是快速抑制电路中的瞬态过压脉冲,将电压钳位在安全范围内,避免后级敏感元器件(如IC、传感器)因过压损坏。其双向极性设计,可同时应对电路中的正、负瞬态脉冲,无需区分正负端安装,简化电路设计流程。

二、关键电气参数深度解析

P4KE15CA的电气参数针对15V电路优化,核心参数及实际意义如下:

  1. 截止与击穿特性:反向截止电压(Vrwm)为12.8V——正常工作时,器件在该电压下反向漏电流极低,不影响电路功能;击穿电压(Vbr)为14.25V——当电路电压超过此值时,器件快速导通,启动过压保护;钳位电压(Vc)为21.2V——导通后将电路电压限制在21.2V以内,确保后级元件不被过压击穿。
  2. 脉冲耐受能力:峰值脉冲电流(Ipp)达18.87A,峰值脉冲功率(Ppp)为400W(测试波形为10/1000μs,即脉冲上升沿10μs、半峰值持续1000μs的标准浪涌波形),可承受强瞬态冲击(如雷击、电机启停浪涌、静电放电)。
  3. 漏电流与稳定性:反向漏电流(Ir)仅1μA(在Vrwm下),远低于常规TVS的漏电流水平,不会对电路正常工作造成额外功耗或信号干扰。

三、物理封装与安装特性

P4KE15CA采用DO-204AL(DO-41)轴向引线封装,具有以下实用优势:

  • 体积紧凑:直径约2.7mm,长度约10mm,空间占用极小,适合高密度PCB布局;
  • 安装便捷:轴向引线设计,支持插件式安装,可直接焊接在PCB板上,无需特殊夹具;
  • 兼容性强:DO-41是行业通用封装,与多数电路设计的引脚间距匹配,替换或升级现有保护器件时无需调整电路。

四、环境适应性与可靠性

P4KE15CA的环境适应性覆盖工业级宽温要求:

  • 工作温度范围:-55℃~+150℃,可在极端高低温环境下稳定工作(如寒冷地区的户外通信设备、高温工业现场的PLC模块);
  • 可靠性:TVS器件属于非破坏性过压保护元件,重复脉冲冲击后参数无明显衰减,可长期稳定运行,无需频繁更换维护。

五、典型应用场景说明

P4KE15CA的参数特性使其适用于多类场景的过压保护:

  1. 通信设备:路由器、交换机、基站的电源端口或信号端口,防止雷击浪涌或静电放电(ESD)损坏核心芯片;
  2. 工业控制:PLC、传感器、执行器的接口电路,应对电机启停、电磁干扰产生的瞬态过压;
  3. 消费电子:电源适配器、充电器的输出端,保护手机、平板等终端设备免受浪涌冲击;
  4. 汽车电子(部分场景):车载充电接口、低功耗传感器电路(若符合汽车级设计规范),应对汽车点火、负载切换产生的瞬态脉冲。

综上,P4KE15CA以双向保护、宽温适配、强脉冲耐受为核心优势,是15V电路过压保护的高性价比选择,可有效提升电路的抗干扰能力与长期可靠性。

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
