Brightking SMCJ16CA-AT/TR13 瞬态抑制二极管(TVS)产品概述

SMCJ16CA-AT/TR13是台湾君耀(Brightking)推出的一款双向瞬态抑制二极管(TVS),专为电子线路的瞬态过压防护设计,兼具小体积、宽温范围与高浪涌耐受能力,适配多种工业、消费及汽车电子场景的防护需求。

一、产品定位与核心属性

该器件属于SMC封装(DO-214AB) 表面贴装TVS,核心定位为双向过压防护元件——可同时抑制正、负方向的瞬态浪涌脉冲,无需区分极性安装,简化电路设计与生产工艺。其核心功能是在电路遭遇雷击、静电放电(ESD)或开关浪涌时,快速导通并钳位电压至安全范围,保护后端敏感元器件(如MCU、传感器、通信芯片等)免受损坏。

二、关键电气参数解析

SMCJ16CA-AT/TR13的电气参数经过优化,平衡了正常工作可靠性与浪涌防护能力,核心参数如下:

  1. 反向截止电压(Vrwm):16V
    指器件在正常工作状态下可承受的最大反向电压,无明显漏电流(反向漏电流Ir≤1μA),确保线路正常信号/电源传输不受干扰。

  2. 击穿电压(Vbr):17.8V
    当电压超过此值时,器件开始从截止态转为导通态,是过压防护的“启动阈值”,避免电压持续上升损坏后端器件。

  3. 钳位电压(Vc):26V
    指在10/1000μs浪涌波形下,器件导通后能将电压钳位至的最大峰值电压(计算逻辑:Vc = Ppp / Ipp = 1500W / 57.7A ≈26V),确保后端器件电压不超过其耐受力极限。

  4. 峰值脉冲电流(Ipp):57.7A
    对应1.5kW峰值脉冲功率(Ppp)的浪涌电流能力,可耐受多次重复浪涌冲击(符合TVS器件的浪涌耐受特性),满足常见工业/消费场景的浪涌防护需求。

  5. 工作温度范围:-55℃~+150℃
    覆盖工业级与汽车级环境温度要求,可在极端低温(如户外工业设备)或高温(如车载电子舱内)场景稳定工作,无需额外散热设计。

三、封装与可靠性设计

SMCJ16CA-AT/TR13采用SMC(DO-214AB)表面贴装封装,具有以下核心优势:

  • 小体积:封装尺寸约3.5mm×2.5mm×1.1mm,适配高密度PCB设计(如智能手机、小型工业控制器),节省电路空间;
  • 自动化兼容:符合表面贴装工艺要求,支持高速贴装生产线,降低生产制造成本;
  • 散热与可靠性:封装结构优化了热传导路径,结合150℃的最高工作温度,可应对脉冲浪涌带来的瞬时温升,长期可靠性符合君耀的工业级品质标准(通过RoHS、无卤素等环保认证)。

四、典型应用场景

基于其双向防护、宽温范围与小封装特性,SMCJ16CA-AT/TR13适用于以下场景:

  1. 消费电子:手机、平板、笔记本电脑的充电接口、USB数据端口,防护ESD与充电浪涌;
  2. 汽车电子:车载信息娱乐系统、传感器接口(如胎压监测、摄像头),满足汽车级温度与振动要求;
  3. 工业控制:PLC模块、工业传感器、电机驱动电路,防护雷击与开关浪涌;
  4. 通信设备:路由器、交换机、基站的信号端口,抑制瞬态过压对通信芯片的损坏。

五、选型与应用注意事项

为确保防护效果,应用时需注意以下要点:

  1. 电压匹配:Vrwm(16V)需≥线路的最大正常工作电压(如12V直流线路适配性良好);
  2. 浪涌耐受:需确认实际浪涌功率≤1.5kW(10/1000μs波形),若浪涌更强可并联多个器件(需注意并联后的电流分配);
  3. 安装位置:应尽可能靠近被保护器件,减少引线电感(引线电感会导致实际钳位电压升高,降低防护效果);
  4. 极性确认:因是双向TVS,无需区分正负极,安装无方向性限制,简化生产流程。

综上,SMCJ16CA-AT/TR13凭借双向防护、宽温范围、小封装与高浪涌耐受能力,成为电子线路瞬态过压防护的高性价比选择,覆盖消费、汽车、工业等多领域应用需求,是替代传统压敏电阻的理想方案。

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.
