P6KE47A/B(单向)产品概述

一、产品简介

P6KE47A/B 为单向瞬态抑制二极管(TVS),采用玻璃钝化结工艺与 DO-204AC(DO-15)轴向封装,专为抑制瞬态电压尖峰设计。器件具备低齐纳阻抗与优良钳位能力,在 10/1000μs 波形下可承受 600W 峰值脉冲功率(重复率/占空比 0.01%),响应速度快,适合保护 I/O 接口与 AC/DC 电源线的过电压冲击。

二、关键电气参数

  • 极性:单向
  • 反向额定电压 Vrwm:40.2 V
  • 击穿电压 VBR:44.7 V(典型)
  • 钳位电压(Ipp 对应):64.8 V
  • 峰值脉冲电流 Ipp:9.4 A(10/1000μs 波形)
  • 峰值脉冲功率 Ppp:600 W(10/1000μs,重复率 0.01%)
  • 反向漏电流 Ir:约 1 μA(在 12 V 以上典型值)
  • 工作温度范围:-55 ℃ 至 +175 ℃

三、主要特性与优势

  • 玻璃钝化结:提高器件可靠性与长期稳定性,耐候性能好。
  • 低齐纳阻抗:在钳位状态下压降小,减小被保护电路受到的应力。
  • 出色的钳位能力:在大电流冲击下保持较低钳位电压,提供有效保护。
  • 快速响应:可在纳秒级响应瞬态尖峰,保护敏感器件免受损坏。
  • 低漏电流:在正常工作电压下对电路影响小,适用于要求低静态功耗的系统。

四、典型应用场景

  • I/O 接口保护:串口、并口、USB、以太网接口等的浪涌和静电防护。
  • AC/DC 电源线路保护:开关电源输入、直流母线、适配器防雷与浪涌吸收。
  • 工业与汽车电子(在符合温度与冲击要求下):对瞬态浪涌、负载开关瞬变的抑制。
  • 其他需对高能瞬态进行钳位的场合,如通信基站、照明驱动等。

五、设计与使用建议

  • 布局:尽量将 TVS 器件靠近被保护端口或电源入口,缩短 PCB 走线,减小寄生感抗与串联阻抗。
  • 散热与功率处理:600W 为峰值脉冲能力(10/1000μs,低占空比);对于重复或较高能量脉冲,应评估器件平均功耗并采取散热或限流措施。
  • 限流元件:必要时在电路中加入熔断器、PTC 或串联阻阻器,以限制持续过流并保护 TVS 本体。
  • 极性确认:该型号为单向 TVS,正向导通通常类似于硅二极管的导通方向,设计时注意接线方向以免误接。
  • 工作环境:器件额定工作温度宽(-55℃ 至 +175℃),但在极端温度与高重复冲击条件下需做可靠性评估。

六、封装与可靠性

  • 封装形式:DO-204AC(DO-15)轴向封装,便于穿孔安装与波峰/手工焊接工艺。
  • 品牌:Brightking(台湾君耀),玻璃钝化封装有利于长期稳定性与抗湿性能。
  • 可靠性建议:生产与测试阶段建议进行浪涌测试(10/1000μs)、温循环与高温存储评估,以确认在实际应用中的表现。

结语:P6KE47A/B(单向)凭借低齐纳阻抗、快速响应与 600W 峰值脉冲能力,适用于各类需要瞬态过压保护的电源与信号接口。在实际选型与设计中,应结合系统电压、可能的浪涌能量与热管理要求,合理布局与配合限流/熔断措施,以保证长期可靠性。若需完整数据表(IV 曲线、钳位曲线、温度系数等)与样片验证,建议联系供应商或参考官方规格书。

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
