P6KE56CA 产品概述

一、产品简介

P6KE56CA 是 Brightking(台湾君耀)出品的一款双向瞬态电压抑制器(TVS)二极管,封装为 DO-204AC(DO-15)轴向封装。该器件专为吸收瞬态浪涌能量设计,用以保护电子系统中的电源线与信号线免受雷击、开关产生的浪涌或静电放电等过压冲击。

二、主要参数

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:47.8 V(工作耐压)
  • 击穿电压(Vbr):53.2 V
  • 钳位电压(Vclamp):77 V(对应峰值脉冲电流)
  • 峰值脉冲电流 Ipp:7.9 A
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs 波形)
  • 反向电流 Ir:1 μA(典型)
  • 工作温度范围:-55 ℃ ~ +175 ℃
  • 类型:TVS 二极管(瞬态抑制)
  • 封装:DO-204AC(DO-15)轴向玻璃/金属封装

三、器件特点

  • 双向设计,可在正负极性瞬态发生时双向钳位,适合交流线路与差分信号保护。
  • 高能量吸收能力:600 W(10/1000 μs)脉冲能力,可承受短时大能量浪涌。
  • 低漏电:典型反向电流仅 1 μA,有利于不影响低电流电路工作。
  • 宽温度范围:-55 ℃ 至 +175 ℃,适用于工业与汽车级别的高温环境(需参照应用规范)。
  • 轴向 DO-15 封装便于通过线束安装或在板间串联保护。

四、关键参数解析

  • Vrwm(47.8 V)为器件在不触发钳位前允许的最大直流工作电压,应保证系统持续工作电压低于此值。
  • Vbr(53.2 V)为击穿起始电压,超过此值时器件进入导通;Vclamp(77 V)是在规定脉冲下的实际钳位电压,用于评估被保护电路所能承受的最大电压。
  • Ppp 与 Ipp 指明了在特定脉冲波形(10/1000 μs)下的能量承受能力与峰值电流能力,设计时要与系统可能出现的脉冲源特性匹配。

五、典型应用

  • 电源输入与线路浪涌保护(DC/AC 电源线路)
  • 通信设备、网路接口的差分线过压防护
  • 工业控制、仪器仪表中对瞬态浪涌的一级防护
  • 汽车电子对车载总线和传感器线的保护(需结合车规认证要求)

六、选型与使用建议

  • 确保工作电压低于 Vrwm,以避免长时间处于击穿区导致器件发热与寿命下降。
  • 对于反复或高能量冲击,建议进行功率余量设计或并联/叠加多级保护。
  • 放置位置应靠近被保护端并尽量缩短引线与回路感抗,减小寄生电感导致的瞬态过压。
  • 焊接和装配时遵守厂家推荐的温度与时间规范,避免超温损伤器件封装或内芯。

七、存储与可靠性

  • 存储环境尽量干燥、避免潮湿与腐蚀性气体,长时间存放建议密封防潮。
  • 在高温或频繁脉冲的工作条件下,应关注器件散热与热斑累积问题,并考虑热仿真验证可靠性。

八、结论

P6KE56CA(77 V,DO-15)是一款适用于需要双向保护、具备较高能量吸收能力的 TVS 器件,凭借低漏电与宽温特性,适合工业与部分苛刻环境的瞬态抑制应用。选用时需综合考虑系统工作电压、可能的脉冲能量及热管理方案,以确保长期可靠运行。

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
