P6KE15CA 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心功能

P6KE15CA是DOWO(东沃)品牌推出的轴向引线式双向瞬态抑制二极管(TVS),核心作用是针对12V~15V等级的电路系统,快速吸收瞬态过压(如雷击浪涌、开关浪涌、ESD静电放电等),将电路两端电压钳位在安全范围内,避免后端敏感电子元器件(如MCU、传感器、通信接口芯片等)因过压损坏。其双向极性设计无需区分正负极,安装与应用更灵活。

二、关键电气参数解析

该器件的电气参数针对中低压电路防护优化,核心参数如下:

  1. 极性与工作电压范围:双向无极性,正常工作时允许的最大反向截止电压(Vrwm)为12.8V,典型击穿电压(Vbr)为14.25V——即当电路电压超过14.25V时,器件快速导通进入保护状态;
  2. 钳位与脉冲承受能力:在10/1000μs(脉冲上升沿10μs、半峰值宽度1000μs)标准浪涌波形下,峰值脉冲功率(Ppp)达600W,对应峰值脉冲电流(Ipp)28.3A,此时钳位电压(Vc)稳定在21.2V——确保后端电路电压不超过21.2V,避免器件击穿;
  3. 漏电流与功耗:在Vrwm(12.8V)下的反向漏电流(Ir)仅1μA,远低于常规电路允许的漏电流范围,不会对正常工作电路造成额外功耗或干扰。

三、封装与物理特性

P6KE15CA采用DO-204AC(DO-15)轴向引线封装,具备以下特点:

  • 尺寸紧凑:轴向引线设计,长度约5.0mm、直径约2.5mm,适合空间受限的电路板布局;
  • 安装便捷:插件式封装,兼容常规波峰焊、手工焊接工艺,批量生产效率高;
  • 机械可靠性:陶瓷或玻璃钝化封装(DO-15典型封装材料),耐冲击、抗振动,适合工业/汽车等振动环境;
  • 制程兼容性:封装材料适配宽温工作范围,支持回流焊等高温制程。

四、典型应用场景

结合参数特性,P6KE15CA适用于以下场景:

  1. 汽车电子系统:12V车载电路(如车身控制器ECU、传感器接口、CAN/LIN总线)的浪涌防护,应对汽车点火、负载切换产生的瞬态过压;
  2. 工业控制设备:PLC输入输出模块、电机驱动电路、现场总线(RS485)的过压保护,适应-55℃~+150℃的宽温工业环境;
  3. 通信接口防护:15V以下的通信设备接口(如工业以太网、Modbus接口),抵御雷击浪涌与静电放电;
  4. 低压电源模块:12V/15V电源输出端的二次防护,防止电源开关切换或外部浪涌损坏负载器件;
  5. 消费电子特殊场景:部分中高端设备的中低压电路(如智能家居控制模块)的瞬态防护。

五、可靠性与环境适应性

  1. 宽温工作范围:-55℃~+150℃的工作温度,覆盖工业级、汽车级(部分等级)的环境要求,可在极端温度下稳定工作;
  2. 多次脉冲稳定性:TVS管可重复吸收瞬态浪涌,P6KE15CA在多次600W脉冲冲击后,仍能保持参数一致性,防护性能不衰减;
  3. 抗干扰性:低漏电流(1μA)与ns级快速响应(TVS管典型特性),确保保护过压的同时,不影响电路正常信号传输。

P6KE15CA凭借双向防护、高脉冲承受能力与宽温适应性,成为中低压电路瞬态过压防护的实用选择,可满足工业、汽车、通信等领域的可靠性需求。

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
