汽车胎压监测系统简称“TPMS”，是“tire pressure monitoring system”的缩写。这种技术可以通过记录轮胎转速或安装在轮胎中的电子传感器，对轮胎的各种状况进行实时自动监测，能够为行驶提供有效的安全保障。

胎压监测系统不仅能在轮胎出现高压，低压，高温时报警提醒车主注意行车安全，而且也能帮助车主节油省钱，成为汽车低碳环保一族。胎压监测系统TPMS相关统计数据显示：汽车缺气行驶将多消耗3.3%的燃油。很多车主可能都不知道轮胎有缓慢自然漏气的现象，轮胎气压不足都浑然不知。

为保护TPMS统系统的可靠运行，硕凯电子顺势推出一款大功率，强防护的车载浪涌防护产品SM8E22A。

SM8E22A为贴片封装（DO-218AB），方便焊接，节省PCB空间。功率高达8000W，能通过ISO 7637-2:2004 标准，可通过车载浪涌5A测试要求。工作电压22V，钳位电压35.5V，工作电压范围在-55 ~ +175℃。

特点：

• 工作电压VR: 22V

• 击穿电压VBR@（5mA）:24.4V -26.9V

• 钳位电压VC @（225A）: 35.5V

应用:

• 车载收音机

• 车灯

• 行车记录仪

• 车载电源

• 360全景摄像

• 车载音响
