1.5KE6.8A单向瞬态抑制二极管(TVS)产品概述

一、产品定位与核心属性

1.5KE6.8A是东沃(DOWO)品牌推出的单向瞬态抑制二极管(TVS),属于过压防护核心器件,专为中功率电路的浪涌、静电及开关瞬态干扰防护设计。采用DO-201AD轴向封装,适配通孔插装工艺,可广泛应用于工业控制、通信接口、低压电源等场景。

二、核心电参数深度解读

TVS管的防护能力依赖关键参数的精准设计,1.5KE6.8A的核心参数与实际意义如下:

  1. 极性与工作电压范围:单向设计,仅针对电路中特定方向的过压防护(需结合电路极性匹配);反向截止电压(Vrwm)=5.8V,即正常工作时反向电压不超过5.8V时器件保持截止,不影响电路正常运行。
  2. 击穿与钳位特性:击穿电压(Vbr)=6.46V(反向漏电流Ir=1mA时的电压),表明器件在6.46V左右开始击穿;关键钳位电压(Vc)=10.5V(10/1000μs波形下),即过压时能将电压稳定在10.5V以内,这是保护后端敏感元件(如MCU、传感器)的核心指标。
  3. 脉冲承受能力:峰值脉冲功率(Ppp)=1.5kW(10/1000μs波形),峰值脉冲电流(Ipp)=142.86A,对应行业标准浪涌波形(10μs上升沿、1000μs下降沿),说明器件可承受1.5kW的瞬态能量冲击,适合中功率电路的浪涌防护需求。

三、封装形式与物理特性

1.5KE6.8A采用DO-201AD轴向封装,具有以下特点:

  • 安装方式:通孔插装,适配PCB板焊接或接线端子连接,安装便捷;
  • 封装材质:玻璃钝化或陶瓷封装,耐温性好(常规工作温度范围-55℃~+150℃),可适应工业环境的温度变化;
  • 尺寸小巧:轴向封装直径约8mm,长度约10mm,不占用过多PCB空间,适合紧凑型电路设计。

四、性能优势与设计亮点

相比同类器件,1.5KE6.8A的核心优势体现在:

  1. 精准防护:钳位电压偏差小(10.5V为典型值,符合行业标准),可精准保护5V/6V系统的敏感元件;
  2. 高能量承受:1.5kW的峰值脉冲功率,满足工业控制、通信设备等场景的浪涌防护需求(如雷击感应浪涌、开关切换浪涌);
  3. 快速响应:TVS管本质响应时间为ns级,可在瞬态过压出现时(如静电放电、浪涌)迅速导通,有效抑制电压尖峰;
  4. 可靠性稳定:东沃品牌的器件一致性好,经过老化测试,适合长期在工业环境中使用。

五、典型应用场景

1.5KE6.8A的参数特性使其适合以下场景:

  1. 低压直流电源系统:5V/6V供电的设备(如小型PLC、传感器模块),防护电源端的浪涌干扰;
  2. 通信接口电路:RS485、RS232、CAN总线等接口的端口防护,避免静电或浪涌损坏通信芯片;
  3. 工业控制设备:变频器、伺服驱动器的辅助电源防护,适应工业现场的电磁干扰环境;
  4. 户外电子设备:如监控摄像头、便携式医疗设备的电源防护,兼顾体积与防护能力。

六、总结

1.5KE6.8A是一款专为中功率电路设计的单向TVS管,凭借1.5kW的脉冲承受能力、精准的10.5V钳位电压及DO-201AD封装的便捷性,成为工业控制、通信接口等领域的可靠过压防护选择。其单向设计适配特定电路方向的防护需求,可有效保护敏感元器件免受浪涌、静电等瞬态干扰的损坏。

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
