P6KE120CA 瞬态抑制二极管(TVS)产品概述

P6KE120CA是东沃(DOWO) 推出的轴向引线型双向瞬态抑制二极管(TVS),专为电子电路瞬态过压防护设计,具备宽温适应性、高浪涌吸收能力及稳定电气特性,适用于工业、汽车、通信等可靠性要求严苛的场景。

一、产品核心定位与应用场景

P6KE120CA属于中高压TVS器件,核心作用是ns级响应抑制瞬态过压(雷击浪涌、开关尖峰、静电放电等),保护后端敏感元件(IC、传感器、电源模块等)免受损坏。典型应用包括:

  • 工业控制:PLC、伺服驱动器的电源/信号接口防护;
  • 汽车电子:发动机传感器、车载通信模块的宽温过压防护;
  • 通信系统:基站、路由器的以太网/射频接口浪涌抑制;
  • 光伏储能:DC侧(光伏板、电池组)的瞬态过压防护;
  • 消费电子:大功率电源适配器的输入/输出端防护。

二、关键电气参数解析

P6KE120CA的参数经严格测试,适配实际防护需求,核心参数及意义如下:

  1. 极性:双向
    支持正负浪涌抑制,无需额外并联反向器件,简化双向信号/电源电路设计。
  2. 反向截止电压(Vrwm):102V
    正常工作时可承受的最大反向电压,确保额定电压下无导通漏电流。
  3. 击穿电压(Vbr):114V
    瞬态过压超该值时快速击穿导通,将浪涌能量导入地端,响应时间达ns级。
  4. 钳位电压(Vc):165V
    10/1000μs浪涌波形下的最大端电压,远低于后端器件损坏阈值,有效防护。
  5. 峰值脉冲电流(Ipp):3.64A
    对应峰值脉冲功率(Ppp)600W,具备较强浪涌吸收能力,适配典型工业浪涌场景。
  6. 反向漏电流(Ir):1μA
    截止状态漏电流极小,不影响电路正常工作,降低静态功耗。
  7. 工作温度:-55℃~+150℃
    覆盖工业级及汽车级温度要求,极端环境下性能稳定。

三、封装与可靠性设计

P6KE120CA采用DO-15封装,具备以下优势:

  • 轴向引线设计:通孔焊接适配传统PCB工艺,安装便捷;
  • 机械强度高:体积小(φ2.5mm×8.5mm),抗振动/冲击能力强,适合工业/汽车振动环境;
  • 散热稳定:金属引线与封装紧密结合,有效散发热量,避免浪涌过热损坏;
  • 浪涌耐久性:经1000次600W浪涌测试,性能无明显衰减,符合IEC 61000-4-5标准。

四、品牌与质量保障

东沃(DOWO)作为专业过压防护器件制造商,P6KE120CA具备:

  • 参数一致性:批量生产离散性小,满足工业批量应用需求;
  • 环保合规:符合RoHS、REACH标准,无有害物质;
  • 技术支持:提供选型、方案设计等配套服务,降低客户开发成本。

五、典型应用示例

以工业24V电源模块输入防护为例:
将P6KE120CA并联在电源输入端(火线/零线-地之间),当电网出现2kV/1.2μs雷击浪涌时,器件快速击穿导通,将浪涌能量导入地端,确保模块输入电压≤165V,避免模块损坏。

综上,P6KE120CA凭借双向防护、宽温特性、高浪涌吸收能力及可靠封装,成为工业、汽车、通信领域过压防护的优选器件。

Sourcing availability signal

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
