Littelfuse P6SMB47CA TVS二极管产品概述

P6SMB47CA是美国力特(Littelfuse)推出的一款双向瞬态抑制二极管(TVS),专为电子电路的瞬态过压防护设计,具备高功率容量、宽温适应和国际标准兼容等特点,广泛应用于消费电子、工业控制、汽车电子等领域。

一、产品核心身份与应用定位

作为TVS二极管家族中的一员,P6SMB47CA的核心作用是快速抑制电路中的瞬态浪涌电压(如静电放电ESD、电快速瞬变脉冲群EFT、雷击感应浪涌等),将电压钳位在安全范围内,避免后端敏感元器件(如MCU、传感器、接口芯片)被击穿损坏。其双向导通特性无需区分正负极,简化了电路设计与生产安装流程,适配各类通用电路的防护需求。

二、关键电气性能参数深度解析

P6SMB47CA的电气参数经过严格校准,精准匹配中等电压等级电路的防护要求:

  • 反向截止电压(Vrwm):40.2V
    正常工作状态下,器件反向可承受的最大电压,低于此值时TVS处于高阻态,不影响电路正常运行。
  • 击穿电压(Vbr):49.4V
    当反向电压超过此值时,TVS迅速从高阻态切换为低阻态,启动过压防护功能。
  • 钳位电压(Vc):64.8V
    浪涌发生时,TVS将电路电压钳位在此值以下,有效保护后端器件(典型器件耐压多在60V以下,此钳位值可覆盖安全防护区间)。
  • 峰值脉冲功率(Ppp):600W@10/1000μs波形
    对应国际标准的10/1000μs浪涌波形(前沿10μs、半值宽1000μs),器件可承受的最大脉冲功率,满足多数民用与工业场景的浪涌强度要求。
  • 峰值脉冲电流(Ipp):9.4A
    同波形下的最大允许脉冲电流,结合钳位电压可直接计算脉冲功率(P=V×I),是防护能力的直观体现。
  • 反向漏电流(Ir):1μA
    正常工作电压下的反向漏电流极低,可忽略不计,不会对电路功耗或信号完整性造成干扰。

三、物理封装与工作环境

P6SMB47CA采用DO-214AA封装(即SMB封装),具备以下特点:

  • 2引脚表面贴装设计,体积小巧(约3.0mm×2.5mm×1.5mm),适配高密度PCB布局;
  • 无铅工艺,符合RoHS环保要求;
  • 工作温度范围:-65℃~+150℃,覆盖工业级(-40℃+85℃)、汽车级(-40℃+125℃)甚至更高温的严苛环境,如户外通信设备、工业控制器、车载电子等。

四、防护标准与典型应用场景

P6SMB47CA通过了IEC 61000-4-4(电快速瞬变脉冲群) 和 IEC 61000-4-2(静电放电) 国际防护标准认证,可有效应对常见的电磁干扰问题。其典型应用场景包括:

  • 消费电子:手机、平板、笔记本电脑的USB接口、HDMI接口防护;
  • 工业控制:PLC输入输出端口、传感器模块、电机驱动电路的过压保护;
  • 汽车电子:车载导航、CAN总线接口、车灯控制电路的瞬态防护;
  • 通信设备:路由器、交换机、基站的RJ45接口、射频端口防护。

五、品牌与可靠性保障

作为全球领先的过压保护器件厂商,Littelfuse(力特)对P6SMB47CA的可靠性进行了严格验证:

  • 采用成熟的TVS芯片设计工艺,确保参数一致性与长期稳定性;
  • 经过高低温循环、湿热老化、机械振动等可靠性测试,满足工业级与汽车级应用的寿命要求;
  • 广泛应用于全球知名电子厂商的产品中,市场验证充分。

总结:P6SMB47CA以双向防护、宽温适应、高功率容量和国际标准兼容为核心优势,是中等电压电路瞬态过压防护的高性价比选择,适用于从消费电子到工业控制的多场景需求。

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
