SMBJ36CA 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心功能

SMBJ36CA是FUXINSEMI(富芯森美)推出的双向瞬态抑制二极管(TVS),属于SMB封装系列,专为36V等级低压电路的过压浪涌防护设计。其核心作用是在电路遭遇瞬态电压尖峰(如ESD静电放电、雷击浪涌、开关瞬态干扰)时,快速导通并钳位电压至安全范围,避免后端敏感元器件(如MCU、传感器、电容)被击穿损坏,是工业控制、汽车电子、通信设备等领域的通用防护器件。

二、关键电气参数解析

SMBJ36CA的参数经过精准设计,适配36V电路的防护需求,核心参数及意义如下:

  1. 反向截止电压(Vrwm):36V
    指器件在正常工作状态下可承受的最大反向电压,此时器件处于截止状态,漏电流极小,不影响电路的正常功耗与信号传输。此参数与电路工作电压匹配,避免误触发防护。

  2. 击穿电压(Vbr):40V
    当反向电压超过40V时,器件开始雪崩击穿导通(可逆过程,浪涌消失后恢复截止),启动防护功能。该参数确保防护动作的及时性,避免电压持续上升损坏后端元件。

  3. 钳位电压(Vc):58.1V
    在额定峰值脉冲电流(Ipp)下,器件两端的最大电压值。当电路出现浪涌时,SMBJ36CA将电压钳位在58.1V以下,远低于多数敏感元件的耐压阈值(如MCU耐压≤60V),有效保护电路安全。

  4. 峰值脉冲电流(Ipp):10.3A
    对应8/20μs标准浪涌波形下的最大耐受电流,体现器件的浪涌能力。10.3A可覆盖常见中等强度浪涌(如汽车点火干扰、工业开关瞬态),满足多数应用场景的防护需求。

  5. 反向漏电流(Ir):5μA
    Vrwm(36V)下的反向漏电流,数值极低可忽略,避免器件自身功耗对电路的影响,尤其适用于低功耗电路。

  6. 工作温度范围:-55℃~+150℃
    宽温设计适配极端环境,可满足工业级(-40℃~+85℃) 甚至部分汽车级(-55℃~+125℃) 场景,如户外传感器、发动机舱电子模块等。

三、封装与物理特性

SMBJ36CA采用SMB封装(DO-214AA),属于小型表面贴装封装,具备以下优势:

  • 尺寸紧凑:典型尺寸为2.9mm(长)×5.0mm(宽)×1.8mm(高),适合高密度PCB布局,尤其适用于小型化电子设备;
  • 双向封装:CA后缀表示双向防护,无需区分正负极,简化电路设计与焊接工艺;
  • 焊接可靠性:引脚间距与焊盘设计符合行业标准,兼容回流焊、波峰焊等工艺,焊接良率高;
  • 环保合规:符合RoHS 2.0、REACH等标准,不含铅、镉等有害物质,适配绿色制造需求。

四、品牌与可靠性优势

FUXINSEMI(富芯森美)是国内专注于功率半导体与防护器件的厂商,SMBJ36CA具备以下可靠性优势:

  • 一致性优异:采用成熟晶圆制造与封装工艺,参数离散性小,批量供货性能稳定;
  • 严格测试:经过ESD(±8kV接触/±15kV空气放电)、浪涌(10.3A/8/20μs)、温度循环(-55℃~+150℃,1000次)等测试,符合IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)等国际标准;
  • 供货稳定:具备规模化生产能力,可满足中小批量到大批量采购,交付周期可控。

五、典型应用场景

SMBJ36CA的参数与封装特性使其适配多领域应用,典型场景包括:

  1. 工业控制:PLC输入输出接口、温度/压力传感器模块的过压防护;
  2. 汽车电子:车载CAN/LIN总线、摄像头、胎压监测系统(TPMS)的浪涌防护;
  3. 消费电子:笔记本电脑、平板的USB Type-C接口、电源端口的ESD防护;
  4. 通信设备:路由器、交换机的以太网接口、电源模块的瞬态电压抑制。

综上,SMBJ36CA凭借双向防护、宽温特性与紧凑封装,成为36V等级电路浪涌防护的高性价比选择,可有效提升电子设备的可靠性与抗干扰能力。

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.
