5KP400CA瞬态抑制二极管(TVS)产品概述

5KP400CA是DOWO东沃推出的一款轴向引线封装(P600)双向瞬态抑制二极管(TVS),专为中高压电路的瞬态过压防护设计,可有效抑制雷击浪涌、静电放电(ESD)、开关瞬态等异常脉冲,保护敏感电子元器件免受损坏。产品具备宽工作温度范围、高峰值脉冲功率及精准钳位特性,适用于工业、汽车、通信等多领域的恶劣环境应用。

一、产品核心定位与功能

TVS作为瞬态过压防护的核心器件,核心作用是在极短时间内(ns级响应)将电路电压钳位至安全范围,避免后级器件因过压击穿损坏。5KP400CA为双向防护型,可同时应对正负方向的瞬态脉冲,无需额外配置极性保护电路,简化电路设计。其峰值脉冲功率达5kW(10/1000μs脉冲波形下),可承受高强度瞬时能量冲击,是中高压电路防护的高性价比选择。

二、关键参数深度解析

产品参数经过严格校准,核心参数的设计与匹配直接决定防护效果,具体解析如下:

  1. 极性与防护方向:双向,兼容正负脉冲防护,适用于无明确极性要求的电路端口(如电源双向接口、信号总线);
  2. 反向截止电压(Vrwm):400V,即器件正常工作时可承受的最大反向直流电压,确保电路在额定电压下稳定运行,无漏电流干扰;
  3. 击穿电压(Vbr):447V(典型值),当电路电压超过此值时,器件快速反向击穿导通,启动防护功能,响应时间小于1ns(TVS常规特性);
  4. 钳位电压(Vc):648V(10/1000μs脉冲下),击穿导通后将电路电压钳位在此范围,比击穿电压高约20%,为后级器件提供安全电压阈值;
  5. 峰值脉冲电流(Ipp):7.72A,与钳位电压匹配(Vc×Ipp≈5000W),可承受瞬时大电流冲击;
  6. 反向漏电流(Ir):2μA(Vrwm下),漏电流极小,不影响电路正常功耗,避免待机损耗;
  7. 工作温度范围:-55℃~+150℃,覆盖工业级与汽车级环境温度要求,可在极端高温(如汽车发动机舱)或低温场景稳定工作。

三、封装设计与可靠性

5KP400CA采用P600轴向引线封装,具备以下优势:

  • 安装便捷:通孔焊接方式,适配传统PCB设计,无需特殊焊接工艺;
  • 散热性能:封装结构紧凑且热阻低,可快速散发明时间内的脉冲能量,避免器件过热损坏;
  • 机械强度:轴向引线设计抗振动性能好,适合汽车、工业等振动环境;
  • 宽温可靠性:封装材料与器件工艺匹配宽温范围,经过高低温循环测试,确保极端环境下参数稳定。

四、典型应用场景

结合参数特性,5KP400CA广泛应用于以下场景:

  1. 工业电源系统:如变频器、PLC、工业UPS的中高压电源端口,防护雷击浪涌与开关瞬态;
  2. 汽车电子:车载高压辅助电源(如48V系统)、车载充电器(OBC)的过压防护,符合汽车级温度要求;
  3. 通信设备:基站电源端口、光纤收发器的雷击防护,双向防护适配总线型电路;
  4. 光伏逆变器:光伏组件与逆变器接口的浪涌防护,应对雷电冲击与开关切换产生的瞬态电压;
  5. 电力监控设备:高压计量装置、智能电表的电源与信号端口防护,确保设备稳定运行。

五、品牌与质量保障

DOWO东沃作为专业电子元器件制造商,其TVS产品线覆盖全系列功率与电压范围,5KP400CA经过严格的可靠性测试(如高低温存储、脉冲寿命测试),参数一致性好,适合批量生产应用。产品符合工业级标准,可提供完整的 datasheet 与测试报告,满足客户的质量追溯需求。

综上,5KP400CA以双向防护、宽温特性、高功率密度及精准钳位为核心优势,是中高压电路瞬态过压防护的可靠解决方案,可有效提升电子设备的抗干扰能力与使用寿命。

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
