P6KE20CA(RUILON)产品概述

一、产品简介

P6KE20CA 是 RUILON(瑞隆源)生产的一款双向瞬态电压抑制二极管(TVS),封装为 DO-15。器件设计用于吸收和钳位电源或信号线上的瞬态过电压,保护敏感电子元件免受雷击、电源开关瞬变或电感性负载释放所产生的大能量脉冲冲击。器件可在宽温度范围内工作,适用于工业级苛刻环境。

二、主要参数(关键指标)

  • 类型:双向 TVS 二极管
  • 标称描述:P6KE20CA(RUILON)
  • 反向截止电压 Vrwm:17.1 V
  • 击穿电压(Vbr):21 V
  • 钳位电压 Vc(Ipp=22 A,10/1000 μs):27.7 V
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs 波形)
  • 峰值脉冲电流 Ipp:22 A(10/1000 μs)
  • 反向漏电流 Ir:1 μA(常温条件)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 极性:双向(双向对称钳位)
  • 封装:DO-15(轴向引线)

三、性能特点

  • 高能量吸收能力:在 10/1000 μs 脉冲下可承受 600 W 峰值功率,适合对抗雷击和线路瞬变。
  • 低钳位电压:在规定脉冲电流下钳位于 27.7 V,能有效限制受保护节点电压,降低后端器件应力。
  • 宽温度适应性:-55 ℃ 至 +150 ℃ 的工作范围满足工业、通信和某些军工级应用需求。
  • 低漏电流:典型反向漏电仅 1 μA,有利于低功耗电路中的长期并联保护。
  • 双向保护:无需极性区分,可用于交流或可双向出现过压的直流系统。

四、典型应用场景

  • 电源输入端与电源总线上对电源瞬变的保护(交流/直流)
  • 通信设备的接口防护(以太网供电、RS-485、CAN 总线等)
  • 工业控制设备、仪表和测控模块的雷击/浪涌防护
  • 子系统和模块间的局部过压防护,作为主防护或二级防护元件

五、安装与典型电路建议

  • 建议将 TVS 器件尽量靠近被保护端口或连接器安装,以最短引线吸收瞬态能量并减小寄生电感。
  • 在高能量环境下可与串联浪涌限流器(如熔断器或PTC)配合使用,以分担能量并提高可靠性。
  • 对于敏感信号线,使用小电容旁路或 RC 滤波与 TVS 结合,可改善抑制效果并降低电磁干扰。
  • 双向器件在交流或双向脉冲场合无需方向性考虑,但在直流系统应注意反复击穿频率与热量积累。

六、可靠性与选型注意事项

  • 该器件额定为单次或有限次数的大能量脉冲吸收(600 W 峰值,10/1000 μs),对重复高能量脉冲场合需进行寿命评估并考虑冗余保护。
  • 钳位电压随脉冲电流和温度会有变化,选型时应以最大瞬态情形下后端器件可承受电压为准,留有安全裕量。
  • DO-15 轴向封装适合贯穿式安装和手工/波峰焊接工艺,若需表面贴装请选用相应的 SMB/SOD-123 等替代封装型号。
  • 在高温环境或散热受限场合,注意器件的热阻与能量吸收限制,必要时提供良好散热或增加外部保护元件。

七、订购信息与包装

  • 型号:P6KE20CA
  • 品牌:RUILON(瑞隆源)
  • 封装:DO-15(轴向)
  • 购买时请确认器件是真正的双向型号(带字母 C 表示双向),并核对批次、测试报告与储存条件以保证一致性与可靠性。

如需针对具体应用的电路示意、热仿真或与其他保护器件(熔断器、限流电阻、滤波元件)组合的设计建议,可以提供电路参数与工作场景,我可以进一步给出细化的保护方案和选型计算。

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
