Brightking P4SMA6.8A/TR13 TVS二极管产品概述

一、产品定位与品牌背景

P4SMA6.8A/TR13是台湾君耀电子(Brightking)推出的单向瞬态抑制二极管(TVS),属于SMA封装系列的低压防护器件,核心针对电子电路中的静电放电(ESD)、浪涌过压冲击设计,旨在保护敏感半导体元件(如MCU、传感器、接口IC)免受不可逆损坏。君耀作为专注过压防护领域的厂商,其产品覆盖消费电子、工业控制、汽车电子等多行业,P4SMA6.8A/TR13延续了品牌在“紧凑性+高可靠性”上的设计优势,符合多项国际标准。

二、关键参数与防护性能

该产品的参数围绕“常态工作稳定性”与“过压防护效率”双向优化,核心指标及意义如下:

(1)常态工作参数

  • 反向截止电压(Vrwm):5.8V
    电路正常工作时,TVS反向截止,不干扰信号/电源传输,适配5V左右的低压供电系统;
  • 击穿电压(Vbr):6.45V(典型值)
    当反向电压超过该阈值时,TVS快速击穿导通,启动防护机制,避免过压持续上升;
  • 反向漏电流(Ir):1mA(额定条件下)
    常态漏电流极小,不额外增加电路功耗,适合对功耗敏感的便携设备。

(2)过压防护参数

  • 钳位电压(Vc):10.5V(峰值脉冲下)
    击穿后将过压钳位在安全范围,保护后级电路(如敏感IC的耐压通常≤15V);
  • 峰值脉冲功率(Ppp):400W
    可承受短时间高能量脉冲冲击,覆盖常见静电与浪涌的能量范围;
  • 峰值脉冲电流(Ipp):39A
    对应400W功率下的峰值电流容量,能应对IEC 61000-4-2标准下的静电放电(接触放电±8kV、空气放电±15kV)。

三、封装与可靠性设计

(1)紧凑封装适配高密度布局

采用SMA(DO-214AC)贴片封装,体积小巧(典型尺寸约2.4mm×1.6mm×1.0mm),适合消费电子、通信设备等对PCB空间要求严格的场景,可直接贴装于接口电路、电源支路等关键防护位置,无需额外占用大面积空间。

(2)宽温与抗环境干扰能力

  • 工作温度范围:-65℃~+150℃
    覆盖工业级与汽车级温度需求,可在低温高寒(如户外传感器)、高温湿热(如车载中控)环境下稳定工作;
  • 防护标准认证:符合IEC 61000-4-2(静电放电防护),能有效抵御人体放电、设备放电带来的瞬态冲击;
  • 焊接可靠性:SMA封装引脚适配回流焊工艺,焊接强度高,长期使用不易出现虚焊、脱落问题。

四、典型应用场景

P4SMA6.8A/TR13因低压防护特性与紧凑封装,广泛应用于以下领域:

(1)消费电子接口防护

手机、平板、笔记本的USB接口、HDMI接口、音频接口等易受静电冲击的位置,可快速泄放静电,保护接口IC与主控芯片;

(2)工业控制电路防护

PLC模块、传感器节点、电机驱动电路的电源端与信号端,应对工业环境中的浪涌干扰(如电机启停产生的瞬态电压),提升设备稳定性;

(3)汽车电子辅助防护

车载中控、胎压传感器、车载通信接口的低压防护,适配汽车级温度范围,满足车载环境的可靠性要求;

(4)通信设备接口防护

基站、路由器、交换机的RJ45接口、射频接口等,抵御雷电感应浪涌与静电放电,保障通信链路稳定。

五、产品优势与应用价值

相比同类低压TVS器件,P4SMA6.8A/TR13具备以下核心优势:

  1. 响应速度快:TVS典型响应时间达ns级,可瞬间启动防护,避免过压击穿敏感元件;
  2. 钳位精度高:10.5V钳位电压稳定,有效降低后级电路的过压风险;
  3. 功率容量匹配:400W峰值功率与39A峰值电流,覆盖多数低压电路的防护需求;
  4. 环境适应性强:宽温范围与IEC 61000-4-2认证,适配严苛应用场景;
  5. 集成度高:SMA封装体积小,便于在高密度PCB上布局。

综上,P4SMA6.8A/TR13是一款专为低压电路过压防护设计的高可靠性器件,可有效提升电子设备的抗干扰能力与使用寿命,是消费电子、工业控制等领域的优选防护元件。

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.
