Transient interference, as commonly referred to, refers to the instantaneous overvoltage generated by electrostatic discharge, electrical fast transient pulse groups, and lightning surges. This transient interference phenomenon seriously endangers the safety of electronic equipment. In the consumer field, it may damage electronic equipment, and in the industrial field, it will affect the production process. Therefore, eliminating surge noise interference and preventing surge damage have always been the core issues related to the safe and reliable operation of electronic equipment.
In order to reduce the impact of transient interference, a variety of measures can be taken, such as using filter components such as absorbers to reduce the common impedance of the PCB grounding wire, keeping the interference source away from sensitive circuits for PCB layout, and selecting key components with reliable performance.
Working principle of TSS tube, a key component
The working mode of TSS tube is similar to that of gas discharge tube. It is an energy transfer type (switching type) protection device with a breakdown voltage ranging from tens to hundreds of volts and a conduction voltage drop of only a few volts; the surge absorption capacity can reach hundreds of amperes or more.
The working process of TSS tube is that when the voltage exceeds the transition voltage, the solid discharge tube discharges and discharges the pulse energy directly to the ground. When the tube current is lower than the holding current, the discharge ends. The following parameters are often considered for selection:
1 Leakage current Idrm: The maximum peak off-state current measured by the solid discharge tube under the maximum applicable voltage Vdrm in the off state.
2 Switching current Is: The maximum current required to enter the on state.
3 Holding current IH: The minimum current required to maintain the on state.
4 Peak current Ipp: The maximum peak current to ensure that the tube is not damaged.
5 On-state current It: The rated maximum continuous on-state current.
6 Peak surge current Itsm within one cycle: The rated maximum AC current that the discharge tube can pass within one cycle.
7 Switching voltage Vs: The maximum voltage that can be applied across the two ends to enter the on state.
8 On-state voltage Vt: The maximum voltage drop of the discharge tube measured at the rated on-state current.
9 Peak off-state voltage Vdrm: The maximum voltage to maintain the discharge tube in the off state.
10 Off-state capacitance Co: The typical capacitance value measured when the discharge tube is in the off state.
11 Current rise rate di/dt. The maximum current rise rate that can be applied.
12 Voltage rise rate dv/dt. The maximum voltage rise rate that can be applied.
