SMBJ6.0CA 瞬态抑制二极管(TVS)产品概述

SMBJ6.0CA是富芯森美(FUXINSEMI)推出的一款双向瞬态抑制二极管(TVS),采用SMB(DO-214AA)贴片封装,专为6V级低电压电路的过压防护设计,可有效抑制静电放电(ESD)、浪涌脉冲等瞬态干扰,保护敏感电子元器件免受损坏。

一、产品核心定位与身份

作为通用型TVS器件,SMBJ6.0CA的核心优势是双向防护无极性——无需区分正负极即可同步抑制正、负过压,简化电路设计;同时适配5V/6V低电压系统,是小型化电子设备的理想防护选择。其封装体积紧凑、焊接便捷,广泛覆盖消费电子、工业控制、汽车电子等领域。

二、关键电气参数深度解析

SMBJ6.0CA的参数精准匹配低电压防护需求,核心指标及实际意义如下:

  1. 反向截止电压(Vrwm):6V
    电路正常工作时,TVS反向不导通的最大电压。若电路电压≤6V(如常见5V系统),器件处于截止状态,不干扰正常电路;电压一旦超此值,立即启动防护。

  2. 钳位电压:10.3V
    过压事件中,TVS将电路电压钳位在10.3V(典型值),确保单片机、传感器等敏感器件的工作电压不超过其耐受极限,避免击穿。

  3. 峰值脉冲电流(Ipp):58.3A
    对应10/1000μs脉冲波形(模拟实际浪涌的上升/持续时间),器件可承受的最大瞬态电流为58.3A,能应对强浪涌(如雷击感应、电源开关瞬态)。

  4. 峰值脉冲功率(Ppp):600W@10/1000μs
    核心防护能力指标——在10/1000μs波形下,最大耗散600W脉冲功率,实现SMB小封装下的高功率密度。

  5. 击穿电压:6.67V
    反向电压超此值时,TVS进入雪崩击穿状态,快速导通泄放能量;与Vrwm的差值仅0.67V,确保防护启动及时性。

  6. 反向漏电流(Ir):800μA
    Vrwm=6V下的漏电流为800μA,属于低漏范围,不增加低功耗电路的额外负担。

三、封装与物理特性

SMBJ6.0CA采用SMB(DO-214AA)贴片封装,具备以下实用优势:

  • 体积小巧:尺寸约3.5mm×2.0mm×1.5mm,适配智能手环、物联网终端等小型设备;
  • 焊接便捷:支持回流焊、波峰焊等自动化工艺,适合批量生产;
  • 散热可靠:引脚与PCB接触面积合理,可有效散发放电产生的热量;
  • 无极性设计:双向防护无需区分正负引脚,降低设计与焊接错误率。

四、典型应用场景

结合参数与封装特点,SMBJ6.0CA的主要应用场景包括:

  1. 5V/6V电源系统:如USB接口、5V单片机电路、低电压电源模块,抑制电源开关瞬态或外部浪涌;
  2. 低电压信号总线:如I2C、SPI、UART通信总线,防止静电放电(ESD)或共模浪涌干扰;
  3. 工业控制模块:如PLC输入输出端口、传感器接口,适应-55℃~+150℃宽温环境;
  4. 汽车电子辅助电路:如车载USB充电口、仪表盘低电压单元,满足汽车级温度与可靠性要求。

五、可靠性与环境适应性

SMBJ6.0CA的工作温度范围为-55℃~+150℃,可适应极端温度(如北方冬季、高温车间);采用TVS雪崩击穿原理,属于可重复使用器件(不同于保险丝熔断),多次承受瞬态干扰不失效。富芯森美作为国内专业品牌,器件经严格可靠性测试(温度循环、湿度测试),适合工业级与汽车级应用。

六、选型与使用注意事项

  1. 选型匹配:若电路正常电压为5V,Vrwm=6V(高于5V)可确保正常工作不导通;需更高防护电压可选择同系列SMBJ10CA等;
  2. 布局要求:TVS需并联在被保护器件的电源/信号引脚与地之间,布线尽量短(减少寄生电感,提升防护速度);
  3. 功率限制:使用时需确保脉冲功率不超600W@10/1000μs,避免过应力损坏。

综上,SMBJ6.0CA是高性价比的双向TVS器件,兼具小体积、宽温适应性与强防护能力,是低电压电路过压防护的可靠选择。

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.
