1.5KE200A 产品概述

一、产品简介

DOWO(东沃)1.5KE200A 为高能量瞬态电压抑制(TVS)二极管,单向极性设计(也提供双向型号)。器件采用玻璃钝化芯片工艺,封装为工业常用的 DO-201,专为保护电源、通信线路和工业电子设备免受雷击、浪涌和开关瞬态过压而设计。峰值脉冲功率能力达到 1500 W(波形 10/1000 μs),重复率(占空比)0.01%,兼顾大冲击能量吸收与长期可靠性。

二、主要参数

  • 极性:单向(有相对应双向型号可选)
  • 反向截止电压 VRWM:171 V
  • 击穿电压 VBR:210 V
  • 钳位电压(Ipp 条件下):274 V
  • 峰值脉冲电流 Ipp:1 A @ 10/1000 μs
  • 峰值脉冲功率 Ppp:1500 W @ 10/1000 μs
  • 反向电流 Ir:5.47 μA(典型,测试条件见规格书)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:DO-201(轴向大功率封装)
  • 环保标准:符合 RoHS

三、关键特性与优势

  • 玻璃钝化芯片:提升表面稳定性和长期漏电流控制,增强高温及潮湿环境下的可靠性。
  • 高冲击能量吸收能力:10/1000 μs 波形下 1500 W 的峰值功率,可应对较长时间尺度的浪涌事件(如雷击后的剩余波形)。
  • 优秀的钳位性能:在规定脉冲条件下钳位电压约 274 V,能将瞬态电压快速限制到受控范围,保护后端电路。
  • 低漏电流:反向电流仅数微安,适用于对静态功耗敏感的系统。
  • 宽工作温度:适合工业级和恶劣环境应用。
  • 快速响应:TVS 器件本质上响应时间极短,可在纳秒级别夹断突发过压。

四、典型应用

  • 工业电源与配电系统浪涌保护
  • 通信设备、电信线路防护
  • 电机控制板、变频器及逆变器的输入输出保护
  • 继电器和开关电路的瞬态抑制
  • 太阳能逆变器、UPS 等需承受雷击/浪涌的系统

五、选型与使用建议

  • 确认系统工作电压与 VRWM 匹配:本型号 VRWM=171 V,适用于直流母线或电源线路的近似额定电压场景,避免在正常工作中频繁触发。
  • PCB 布局:将 TVS 放置于受保护元件与可能入侵的干扰源之间,尽量缩短导线长度,增大铜箔面积以利散热。
  • 热管理与散热:在高能量冲击场景下,DO-201 封装会产生显著热量,需考虑热散布路径或外加散热措施以提升重复脉冲承受能力。
  • 重复冲击注意事项:Ppp 与 Ipp 参数对应特定波形和占空比,频繁或更高能量的冲击需选型更高能量等级或并联/配合熔断器保护。
  • 极性与双向选择:对直流电源侧优选单向型号;对交流信号线或需双向钳位的场景选择双向型号。

六、封装与可靠性

DO-201 轴向封装便于手工焊接与波峰/回流焊兼容,结构稳固,适用高能量吸收场合。器件符合 RoHS 环保要求,玻璃钝化工艺使得器件在温度循环、湿度应力和长期工作下保持稳定的电气参数。建议在实际应用中参考厂商完整规格书以获得更详细的测试条件和可靠性数据。

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
