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。
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:
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。
P4SMA6.8A/TR13因低压防护特性与紧凑封装,广泛应用于以下领域:
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;
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;
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;
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。
相比同类低压TVS器件,P4SMA6.8A/TR13具备以下核心优势:
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
