Brightking SMCJ5.0CA-AT/TR13 汽车级TVS二极管产品概述

SMCJ5.0CA-AT/TR13是台湾君耀(Brightking)推出的汽车级瞬态抑制二极管(TVS),专为汽车电子及高可靠性场景的过压防护设计。该器件采用SMC(DO-214AB)贴片封装,具备双向防护、高脉冲耐受能力,是车载传感器、ECU、通信接口等模块的核心防护元件。

一、核心身份与封装特征

1. 品牌与型号定位

  • 品牌:Brightking(台湾君耀),国内专注瞬态防护的老牌厂商,汽车级产品覆盖车载全场景需求,符合AEC-Q101等行业标准。
  • 型号含义:
    • SMCJ:贴片式TVS系列(1.5kW功率等级);
    • 5.0:反向截止电压(Vrwm)为5V;
    • CA:双向防护(适配正负脉冲);
    • AT/TR13:SMC封装+卷带编带包装(适合自动化贴装)。
  • 封装:SMC(DO-214AB),尺寸约3.0×2.5×1.5mm,两端引脚设计,兼容回流焊/波峰焊,机械强度高,抗汽车行驶振动。

二、关键电气参数解析

该器件参数围绕**“瞬态过压防护”**核心功能设计,关键指标如下:

1. 防护方向与基础电压

  • 双向极性:支持正负脉冲双向防护,适配汽车电路中正负线均可能出现的浪涌(如点火干扰、负载切换反向脉冲)。
  • 反向截止电压(Vrwm):5V,正常工作时无浪涌的最大反向电压,漏电流极小不影响后级。
  • 击穿电压(Vbr):6.4V(典型值),电压超5V后逐步击穿,为浪涌电流提供泄放通道。

2. 浪涌耐受能力

  • 钳位电压(Vc):9.2V(@163A),浪涌时将电压钳位在安全值,保护3.3V/5V等后级芯片。
  • 峰值脉冲电流(Ipp):163A(8/20μs脉冲),行业标准波形下的最大耐受电流,应对点火、静电放电(ESD)等强浪涌。
  • 峰值脉冲功率(Ppp):1.5kW(8/20μs脉冲),满足车载多数瞬态浪涌的功率需求。

3. 可靠性与环境适应性

  • 反向漏电流(Ir):800μA(@5V),低漏设计避免静态功耗过大,适合低功耗车载模块(如传感器)。
  • 工作温度:-55℃+150℃,覆盖汽车发动机舱(-40℃125℃)、车身(-55℃~85℃)等极端场景。

三、汽车级可靠性设计亮点

汽车电子对器件的抗振动、温度稳定性、浪涌耐久性要求远高于普通消费级,该器件针对性设计:

  1. 封装抗振动:陶瓷/塑料复合结构,引脚与封装结合牢固,通过10G/2000Hz振动测试,避免行驶中脱落。
  2. 温度稳定性:-55℃~150℃内,击穿电压变化≤±10%,漏电流波动小,极端温度下防护一致。
  3. 浪涌耐久性:1000次8/20μs脉冲冲击后参数无衰减,满足汽车10年/15万公里寿命需求。

四、典型应用场景

该器件广泛应用于车载核心模块及周边系统:

  1. 车载传感器防护:胎压监测(TPMS)、摄像头、雷达、氧传感器的电源/信号端口,防护点火干扰、ESD。
  2. 车载通信接口:CAN总线、LIN总线、以太网接口,避免过压导致通信中断。
  3. ECU电源防护:发动机、车身ECU的12V电源输入,防护负载切换浪涌。
  4. 车载娱乐/充电:中控屏、音响、车载充电器的电源输入,防护启动电压波动。

五、应用选型注意事项

  1. 选型匹配:
    • 后级为3.3V/5V电路时,选5V Vrwm(留10%~20%余量);
    • 浪涌功率不足时,可并联多个器件(注意均流)。
  2. 布局建议:
    • 靠近防护端口(如电源接头),减少引线电感(避免钳位效果下降);
    • 与后级并联,串联电阻≤1Ω(防止分压过大)。
  3. 焊接要求:
    • 回流焊峰值温度260℃(10秒内),避免手工焊温度>300℃损坏封装。

总结

SMCJ5.0CA-AT/TR13是君耀汽车级TVS的经典型号,平衡了防护性能、可靠性与成本,适配多数车载模块的过压防护需求。其双向防护、高脉冲耐受、宽温范围等特性,使其成为汽车电子工程师的常用选型,也可拓展至工业控制、通信设备等高可靠性场景。

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.
