Brightking P6KE220A/B 瞬态抑制二极管(TVS)产品概述

Brightking P6KE220A/B是一款600W峰值功率的瞬态抑制二极管,采用经典DO-15轴向封装,专为电子电路中的瞬态过压防护设计,涵盖单向(A系列)、双向(B系列)两种极性,适配不同场景的浪涌抑制需求,是工业控制、电源系统等领域的实用保护器件。

一、核心定位与价值

该系列TVS聚焦中功率高压场景的瞬态防护,核心价值体现在三个方面:

  1. 快速响应:导通时间仅为纳秒级(典型1ns以内),能瞬间抑制浪涌电压,避免电路元件被击穿;
  2. 高功率容量:600W峰值脉冲功率可承受典型浪涌冲击(如8/20μs波形),适配185V及以下静态电压的电路;
  3. 紧凑适配:DO-15封装体积小,轴向引线便于PCB插装,适合空间受限的电路设计。

二、关键电气参数解析

基于产品规格,核心参数的实际意义需结合应用场景理解:

  • 反向截止电压(Vrwm=185V):电路静态工作时,TVS反向承受的最大直流电压,确保不影响正常信号传输;
  • 击穿电压(Vbr=209V):浪涌电压超过此值时,TVS从截止态转为导通态,是过压触发的阈值(通常Vbr为Vrwm的1.1-1.2倍,符合TVS设计逻辑);
  • 钳位电压(Vc=328V):峰值脉冲电流(Ipp=1.9A)通过时,TVS两端的最大电压,直接决定被保护电路的安全上限(Vc越低,保护效果越好);
  • 峰值脉冲电流(Ipp=1.9A):8/20μs浪涌波形下的最大允许电流,与钳位电压乘积(≈623W)接近标称600W峰值功率,是浪涌耐受能力的直观体现;
  • 反向漏电流(Ir=1μA):Vrwm下的反向电流,数值极小,不影响电路静态功耗,保证长期工作稳定性。

三、封装与物理特性

P6KE220A/B采用DO-15(DO-204AC)轴向塑料封装,关键物理特性:

  • 尺寸:直径≈2.5mm,长度≈8.5mm,引脚间距≈5mm,适配标准PCB插装;
  • 引脚:镀锡铜材质,耐焊接温度(260℃/10s),机械强度可靠;
  • 封装材料:阻燃塑料,符合UL 94V-0防火等级,适应工业环境的高温、湿度需求。

四、典型应用场景

结合185V截止电压与600W功率容量,该系列TVS适用于以下场景:

  1. 工业控制电路:PLC输入输出模块、传感器接口的浪涌防护(工业现场易受雷击、电机开关浪涌影响);
  2. 低压高压电源:120V/220V直流电源的输出端保护,防止雷击浪涌损坏电源模块或负载;
  3. 通信设备:无线基站射频接口、光端机电源端口的静电(ESD)与浪涌抑制;
  4. 家电控制电路:变频空调压缩机驱动电路、高端洗衣机高压控制模块的过压防护。

五、A/B系列选型差异

A/B系列的核心区别在于极性:

  • P6KE220A(单向):仅反向导通(阳极接低电位,阴极接高电位),适用于单向浪涌场景(如电源正极→地);
  • P6KE220B(双向):双向导通,适用于交流信号、双向浪涌路径(如通信线路、交流电源端口)。

六、可靠性与品牌优势

Brightking(台湾君耀)作为专业TVS制造商,该系列产品具备以下优势:

  • 符合国际标准:通过IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)测试,满足工业级可靠性要求;
  • 批量稳定性:多次重复浪涌冲击后,电气参数无明显衰减,适合大规模量产应用;
  • 性价比优势:在同等性能下,成本优于部分进口品牌,适配中低端至高端电路的成本控制需求。

该系列TVS以“高性价比+可靠防护”为核心,是电子电路过压防护的实用选择,适配多场景的瞬态浪涌抑制需求。

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
