TVS瞬态抑制二极管用在哪里?
本文介绍了瞬态抑制电压二极管(TVS)的应用场景,希望对各位工程师有所帮助。
【选型】国产TVS瞬态抑制二极管用于POE摄像头保护电路设计,ESD等级±15kV,峰值脉冲功率1500W
针对摄像头POE交换芯片的ESD防护应用,推荐国产硕凯电子的TVS瞬态抑制二极管SMCJ51CA,双向防护,工作电压51V,最小击穿电压56.7V,反向漏电流5μA,峰值脉冲功率1500W,ESD防护等级满足IEC61000-4-2标准。
【技术】浅析瞬态抑制二极管(双向TVS管)
TVS管也叫瞬态抑制二极管,TVS管是吸收浪涌功率用的,能在极短时间内承受反向电压冲击,使两极间的电压钳位于一个特定电压上,避免后面的电路受到冲击。简单的说就是做过压保护的,在通信等产品中很常见。连接时必须反向工作在电路电源、地两端,与稳压二极管类似,但不需要限流电阻。
大功率TVS管在DC24V电源端口防护方案中的应用
DC24V电源广泛使用在LED、安防电源等行业,远距离户外传输,导致设备及易遭受雷击浪涌及过压等损坏,此方案采用UN公司经过多年经验积累开发出来大同流的TVS管,响应速度快、残压低,使后端的电路得到全面的防护。
【经验】解析深井地震探测设备雷击浪涌多极GDT陶瓷放电管与TVS管组合整改案例
本文介绍了优恩半导体雷击浪涌GDT陶瓷放电管与TVS管组合整改案例。案例问题描述的客户产品为深井地震探测仪,设备分为井下传感器、电源供电及通讯接口和井上地面设备数据采集器两部分,中间通过一根多芯铠装电缆承载,多芯线缆包括模拟信号、数字信号、供电和RS485信号。
【产品】贴片DO-218AB封装TVS瞬态抑制二极管SM8S系列,脉冲功率为6600W
电安科技推出的贴片DO-218AB封装TVS瞬态抑制二极管SM8S系列采用玻璃钝化工艺,有单极性和双极性之分,脉冲功率为6600W(10/1000u波形),Vrm电压从10V到43V,工作时的环境温度为-55~150℃,有卓越的钳位能力,反向漏电流小,响应时间快等优点。满足AEC-Q101认证要求;符合Rohs环保要求。

【经验】优恩半导体解析电路保护套件TVS二极管与PPTC的具体作用
首先电子元器件我们可它分为两个大类:过压保护器件与过流保护器件。过流保护器件产品一般为自恢复保险丝(PPTC)、一次性保险丝为主要代表。优恩给大家介绍一下电路保护套件典型产品TVS二极管与PPTC的具体作用。
【技术】一文介绍TVS瞬态抑制二极管原理及应用
随着科技的不断进步,电子设备在我们日常生活和工业生产中扮演着越来越重要的角色。电子设备常常面临来自外部环境的瞬态电压冲击,如雷击、静电放电和电源电压突变等。这些瞬态电压冲击可能导致设备故障、数据丢失或损坏,因此,保护电子设备免受这些瞬态冲击的损害显得尤为重要。
