里阳P6SMAJ-Q和SMBJ-Q系列TVS助力24V车灯系统电源电路防护,峰值脉冲功率高达600W
在现代汽车制造中,车灯系统不仅是车辆外观的重要组成部分,更是确保行车安全的关键元素。
随着汽车电子化、智能化程度的不断提升,车灯系统面临着更加复杂和严苛的工作环境,对电子元器件的可靠性和稳定性提出了更高要求。
车灯的种类
汽车的车灯,包括前照灯、雾灯、日间行车灯、转向灯等。
在车辆行驶过程中需要频繁开关,且经常暴露在极端天气条件下,如高温、潮湿、雷电等。这些环境因素都会对车灯系统的电路造成不同程度的损害,进而影响车灯的正常工作,甚至损坏电路元件。
TVS作为一种重要的电路保护元件,能够迅速响应并抑制电路产生的瞬态冲击,保护车灯系统免受EOS损害。
产品简介
里阳半导体的P6SMAJ30CA-Q、P6SMAJ33CA-Q、SMBJ30CA-Q、SMBJ33CA-Q、常用于24V车灯系统的电源电路防护,这些产品具有出色的钳位能力和600W的峰值脉冲功率,能在极短时间内(pS级)响应电压瞬变,有效抑制开关、静电放电等引起的尖峰电压。
P6SMAJ-Q系列和SMBJ-Q系列适用于汽车电子领域,能保护敏感电子设备免受瞬态脉冲损害。
其封装小巧便捷,适用于空间受限的电路板,且符合AEC-Q101标准。

SMBJ30CA-Q和SMBJ33CA-Q电性参数如下:
应用方案
车灯系统的电源端口是瞬态脉冲的主要入侵路径之一。
通过在电源端口并联合适的TVS,可以有效抑制来自电源线的瞬态脉冲,保护车灯系统的电源电路不受损害。
里阳半导体的P6SMAJ-Q和SMBJ-Q系列产品,均满足ISO10605、ISO7637-2等国际标准,能够达到车灯系统对电源端口防护的要求。
SMBJ30CA-Q可过ISO7637-2测试,测试波形图如下:
车灯系统中的CAN线、LIN线等信号线也容易受到瞬态脉冲的干扰。
CAN线上常用LY23DC24-Q,LIN线常用LY323DC1524L来保护信号电路免受瞬态脉冲的损害,确保信号传输的稳定性和可靠性。
CAN线保护电路如下:
LIN线保护电路如下:
结语
面对瞬态过电压的潜在威胁,采取有效的保护措施对于维护车灯系统的稳定运行至关重要。

什么是TVS二极管,有什么作用呢?
TVS二极管全名叫瞬态抑制二极管,又叫钳位型二极管,是一种限压保护器件,英文Transient Voltage Suppression,作用与压敏电阻很类似。也是利用器件的非线性特性将过电压钳位到一个较低的电压值实现对后级电路的保护。
