1)电力系统保护:在电力系统中,电压溘然升高或溘然降落可能会导致电气设备受损或故障。400V以上的TVS可用于保护变压器、发电机和其他电力设备免受过电压或电涌的影响。
2)工业自动化:在工业掌握系统中,存在着由于电源噪声、静电放电或电磁滋扰等缘故原由引起的电压突变风险。高压TVS可以作为保护装置,防止这些突变对工业设备造成破坏。
3)电信设备保护:通信基站和其他电信设备面临来自雷击、电力供应问题和其他电源滋扰的风险。高压TVS可用于供应保护,防止过压和过电流对设备产生不良影响。

4)汽车电子系统:汽车电子设备须要保护免受电源滋扰、电磁辐射和电压颠簸等成分的影响。高压TVS可用于保护车载电子设备,确保其正常运行并延长寿命。
须要把稳的是,以上仅列举了一些常见的运用领域,实际上高压TVS还可用于其他须要保护电子设备免受过电压影响的场合。详细运用需根据实际情形进行评估和选择。

产品信息:Information of TVS
The transient Voltage Suppressor, referred to as TVS, the TVS operates by shunting excess current when the induced voltage exceeds the avalanche breakdown potential. It is a clamping device, suppressing all over voltages above its breakdown voltage. It automatically resets when the overvoltage goes away, but absorbs much more of the transient energy internally than a similarly rated crowbar device.
The selection tips of TVS
1. The Vrwm of TVS should be more than 10% working voltage and tolerance, that protect the Max DC or continuous working voltage of circuits. If the Vrwm is too low, the device will affect the normal work of the circuits because of the snow slide or reverse electric leakage. The current will be divided in the parallel circuit and the voltage will be divided in the serial circuit.
2. The VC of TVS should be less than the damaged voltage of protecting circuits.
3. The Ppp of TVS should be more than the possible peak pulse of protecting circuits.
4. The Ipp of TVS should be more than the surge current of transient circuit.
5. For the lightning protection of data interface circuit, the semiconductor ESD of low capacitance is better.
6. The selection of TVS’ polarity and encapsulation structure should based the application. For the AC circuit, the dual polarity TVS is better, and for the Multi-line protection, the ESD array of semiconductor is better.返回搜狐,查看更多
