P6KE150A/B 产品概述

一、产品简介

P6KE150A/B 是一款单向瞬态电压抑制二极管(TVS),由 Brightking(台湾君耀)提供,封装为 DO-204AC(也称 DO-15)轴向引线结构。器件采用玻璃钝化结工艺,具有低齐纳阻抗、快速响应和优异的钳位能力,专为吸收脉冲过电压和浪涌能量设计,适用于 I/O 接口及 AC/DC 电源等过压保护场合。

二、主要特性

  • 极性:单向(单向 TVS,用于保护直流或具有极性要求的线路)。
  • 玻璃钝化结:提高长期稳定性、低漏电并改善温度特性。
  • 低齐纳阻抗:在同等浪涌电流下实现较低钳位电压,减少被保护电路应力。
  • 快速响应:对瞬态(如雷击、开关瞬变)能在亚微秒级响应。
  • 10/1000 μs 波形下 600 W 峰值脉冲功率能力(占空比 0.01%)。
  • 典型反向静态电流 Ir ≤ 1 μA(在 Vrwm 条件下或 12 V 以上情形下典型很小)。
  • 宽工作温度范围:-55 ℃ ~ +175 ℃,适合高温或工业级环境。

三、关键电气参数(典型/典型测试条件)

  • 反向截止电压 Vrwm(工作电压):128 V
  • 击穿电压 VBR:143 V(开启区间,测试电流按厂家定义)
  • 钳位电压 Vc(在 10/1000 μs 波形下 Ipp = 2.9 A):约 207 V
  • 峰值脉冲电流 Ipp(10/1000 μs):2.9 A
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs,重复率/占空比 0.01%)
  • 反向电流 Ir:典型 ≤ 1 μA(在 Vrwm 条件下)
  • 工作温度:-55 ℃ ~ +175 ℃

说明:在 10/1000 μs 测试波形下的钳位电压与峰值脉冲电流共同决定瞬态吸收能力:207 V × 2.9 A ≈ 600 W,符合器件标称峰值功率。

四、封装与热性能

  • 封装形式:DO-204AC(DO-15)轴向引线,便于穿孔安装与手工焊接。
  • 热稳定性好:允许在高温环境工作,适合电源侧、工业控制等对耐热性要求高的应用。
  • 封装与散热:作为瞬态吸收元件,通常并联在被保护线路上,良好的器件到散热体或机壳热路径可改善重复浪涌能力与可靠性。

五、典型应用场景

  • 交流/直流电源输入保护(对 110–120 VAC 或直流 128 V 级别的线路防浪涌)。
  • I/O 接口、通信线路防护(串行/并行接口、电源线接口)。
  • 工业控制、逆变器、伺服驱动等需抵抗高能瞬态的场合。
  • 电源滤波与浪涌缓冲电路,与熔断器、限流电阻配合使用以提升系统整体防护能力。

六、设计与选型建议

  • 选择 Vrwm 时应高于系统正常工作电压并留有裕量:例如用于 110–120 VAC 系统时,Vrwm=128 V 属于常见选择。
  • 对于高能脉冲或多次重复冲击场合,应评估器件在实际占空比和环境温度下的累积热应力,必要时增加串联限流或外置熔断保护。
  • 钳位电压决定被保护器件在浪涌时承受的最大尖峰电压,若被保护电路敏感,需选择更低钳位电压或配合其它保护元件(如气体放电管、MOV)。
  • 注意器件的单向极性:在双向交流无极性保护场合,应选用相应的双向型号或两只单向器件反向并联。

七、可靠性与使用注意

  • 重复率(占空比)限制:Ppp 标注基于 0.01% 的占空比,长时间高频重复冲击会降低寿命。
  • 连续工作电压不可长时间超过 Vrwm,否则会产生较大漏电和发热,可能导致器件失效。
  • 焊接与存储:遵循制造商的焊接温度曲线与存储条件,避免过度机械应力影响引线或封装密封性。
  • 在高静电或高能脉冲环境中使用时,配合系统接地和屏蔽设计可显著提升防护效果。

八、订购建议与替代信息

  • 型号示例:Brightking P6KE150A(单向,DO-204AC)。后缀 A/B 在不同供应商或版本中可能表示制造批次或性能容差差异,订购前请参阅供应商的完整数据手册以确认具体电气参数和封装标识。
  • 若需更低钳位或更高能量吸收能力,可参考同系列不同 Vrwm/Vc 等级或更大功率的 TVS 产品;在空间受限时可考虑 SMD 封装的等效器件,但需注意热散与功率承受差异。

如需基于实际电路(工作电压、允许钳位峰值、预期冲击能量与重复率)进行型号精确匹配和仿真计算,可提供系统参数以便给出更具体的选型和保护电路建议。

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.
