P6KE30CA 瞬态抑制二极管(TVS)产品概述

一、产品核心定位与应用场景

P6KE30CA是东沃(DOWO)推出的双向瞬态抑制二极管(TVS),专为电子电路的瞬态过压防护设计,可有效抑制雷击、静电放电(ESD)、开关浪涌等瞬态脉冲对敏感元器件的损坏。其采用DO-15轴向引线封装,体积小巧、安装便捷,广泛适配以下场景:

  • 消费电子:手机、平板、笔记本电脑的充电端口、数据接口防护;
  • 工业控制:PLC输入输出模块、传感器信号线路的过压保护;
  • 汽车电子:车载CAN总线、12V/24V电源系统的浪涌防护;
  • 通信设备:路由器、交换机的以太网端口、射频接口防护。

二、关键电气参数详解

该产品的核心参数围绕“过压保护阈值”“脉冲耐受能力”两大维度设计,具体如下:

1. 极性与截止/击穿特性

  • 双向极性:无需区分正负极,可直接并联于电路两端,简化安装流程;
  • 反向截止电压(Vrwm):25.6V,即电路正常工作时,TVS处于截止状态可承受的最大直流/峰值脉冲电压;
  • 击穿电压(Vbr):28.5V,当电路电压超过此值时,TVS快速击穿导通,启动过压保护;
  • 反向漏电流(Ir):1μA(截止状态下),漏电流极小,不影响电路正常工作。

2. 钳位与脉冲耐受能力

  • 钳位电压(Vc):41.4V,TVS导通后将电路电压钳位在此值,防止后端元器件过压损坏;
  • 峰值脉冲电流(Ipp):14.49A(10/1000μs浪涌波形下),即单次脉冲可耐受的最大电流;
  • 峰值脉冲功率(Ppp):600W(10/1000μs波形),通过Vc×Ipp计算验证(41.4V×14.49A≈600W),满足中等功率浪涌的防护需求。

注:10/1000μs为国际标准浪涌波形(上升时间10μs,半峰值时间1000μs),覆盖大部分工业/消费电子场景的浪涌类型。

三、物理封装与可靠性设计

P6KE30CA采用DO-15轴向引线封装,具备以下优势:

  • 体积小巧:直径约2.7mm,长度约8.4mm,适配紧凑电路设计;
  • 安装便捷:轴向引脚可直接焊接于PCB通孔,无需特殊夹具;
  • 可靠性高:环氧树脂封装耐温(典型工作温度-55℃~+150℃)、耐潮湿,引脚与封装结合牢固,避免虚焊或引脚脱落;
  • 兼容性强:适配手工焊接或自动贴装工艺,可用于各类电路板设计。

四、典型应用电路参考

1. 直流电源端口防护

电路结构:直流电源输入(Vcc)→ 保险丝 → P6KE30CA(并联于Vcc与地)→ 后端负载(如电源管理芯片)。

  • 正常工作:TVS截止,不影响电源供电;
  • 过压触发:当浪涌电压超过28.5V时,TVS击穿导通,将电压钳位至41.4V以下,保护后端芯片。

2. 差分信号线路防护

以RS485总线为例:

  • 信号A与地并联一个P6KE30CA,信号B与地并联一个P6KE30CA;
  • 双向极性无需区分A/B线正负,可有效抑制总线浪涌或静电对收发器的损坏。

五、选型与使用注意事项

  1. 参数匹配原则:

    • Vrwm需大于电路正常工作的最大电压(如24V电源系统,25.6V Vrwm可满足);
    • Vc需小于后端元器件的最大耐受电压(如后端芯片耐压≥45V,可保证保护有效);
    • Ppp需大于电路可能遇到的最大浪涌功率(如600W可覆盖多数工业设备浪涌)。
  2. 安装要点:

    • 尽量靠近被保护电路的输入端,减少引线电感(引线电感会导致钳位电压升高);
    • 焊接时避免引脚过度弯曲,防止封装开裂;
    • 高压场景下需注意引脚间距,避免爬电。
  3. 维护建议:

    • 避免长期工作在超过Vrwm的电压下,防止TVS老化;
    • 工业设备可定期检测TVS漏电流(若漏电流>10μA,需更换)。

P6KE30CA凭借双向防护、中等功率耐受能力及紧凑封装,成为各类电子设备过压保护的实用选型,可有效提升电路抗干扰能力与可靠性。

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.
