SMBJ6.0A 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心功能

SMBJ6.0A是乐山无线电(LRC)推出的双向瞬态抑制二极管(TVS),属于SMB封装系列,核心定位为6V工作电压系统的过压保护器件。其核心功能是快速响应电路中的瞬态浪涌(如静电放电、雷击感应、开关浪涌等),将浪涌电压钳位在安全范围内,避免后端敏感电子元件(如IC、传感器、通信接口)因过压损坏,保障系统稳定运行。

二、关键电气参数详解

该产品的电气参数精准匹配6V系统需求,核心参数如下:

1. 电压类参数

  • 反向截止电压(Vrwm):6V:正常工作状态下,器件反向截止,不影响电路信号传输;
  • 击穿电压(Vbr):7.37V:当浪涌电压超过此值时,器件快速击穿导通,启动保护;
  • 钳位电压(Vc):10.3V:击穿导通后,将浪涌电压钳位至10.3V以下,确保后端元件耐压安全(需确认后端元件耐压≥10.3V)。

2. 浪涌耐受能力

  • 峰值脉冲电流(Ipp):58.3A:1ms脉冲宽度下,可承受的最大浪涌电流,满足多数中低功率系统的浪涌需求;
  • 峰值脉冲功率(Ppp):600W@1ms:1ms脉冲周期内的最大功耗,直接体现器件抗浪涌能力,可有效抑制常见瞬态浪涌(如IEC 61000-4-2静电放电、IEC 61000-4-5浪涌)。

3. 漏电流与极性

  • 反向漏电流(Ir):800μA:Vrwm=6V时的反向漏电流,数值小,不影响系统正常功耗;
  • 极性:双向:无需区分正负极,简化电路设计与安装,适合双向信号/电源线路保护。

三、封装与物理特性

SMBJ6.0A采用SMB封装(DO-214AA),该封装具有以下优势:

  1. 体积紧凑:尺寸约3.5mm×2.5mm×1.5mm,适合高密度PCB布局(如IoT模块、小型控制器);
  2. 表面贴装:支持自动化贴装(SMT),生产效率高,降低人工成本;
  3. 散热性良好:封装结构利于热量扩散,适合重复浪涌场景下的长期稳定工作;
  4. 无极性安装:双向TVS无需区分引脚极性,安装时无需额外检查,减少出错率。

四、典型应用场景

该产品针对6V系统的过压保护需求,广泛应用于以下场景:

  1. 低电压数字电路:单片机(MCU)、FPGA、DSP等核心芯片的IO口、电源端保护;
  2. 通信接口:RS485、CAN总线、UART等工业/汽车通信接口的过压防护;
  3. 汽车电子:车载传感器(温度、压力传感器)、小功率控制电路(车灯、门锁控制)的浪涌保护(适配宽温);
  4. 消费电子:小型充电设备(蓝牙耳机充电盒)、IoT终端(智能传感器节点)的电源端保护;
  5. 工业控制:PLC输入输出(I/O)端口、远程IO模块、工业传感器的过压防护。

五、可靠性与环境适应性

  1. 宽温度范围:工作温度为**-55℃~+150℃**,可适应极端环境(工业高温车间、户外低温场景);
  2. 品牌品质:乐山无线电(LRC)为国内半导体龙头,产品符合RoHS无铅环保要求,重复浪涌测试后性能稳定;
  3. 行业标准兼容:参数满足IEC 61000-4系列浪涌测试标准,可直接用于符合EMC要求的系统设计。

六、总结

SMBJ6.0A是一款高性价比双向TVS二极管,精准匹配6V系统过压保护需求,具有浪涌能力强、封装紧凑、宽温适应、安装简便等优势。其核心参数(600W@1ms脉冲功率、10.3V钳位电压)可有效抑制常见瞬态浪涌,保护后端敏感元件,广泛适用于工业、汽车、消费电子等领域,是电子系统过压防护的可靠选择。

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.
