Product performance:
Ceramic gas discharge tube is the most widely used switching device in lightning protection equipment. Whether it is lightning protection for AC or DC power supplies or lightning protection for various signal circuits, it can be used to discharge lightning current into the earth. Its main characteristics are: large discharge current, small inter-electrode capacitance (≤3pF), high insulation resistance (≥109Ω), large breakdown voltage dispersion (±20%), and slightly slower reaction speed (the shortest is 0.1~0.2μs). ). According to the number of electrodes, there are two types: diode discharge tubes and triode discharge tubes (equivalent to two diode discharge tubes connected in series). Its appearance is cylindrical, and it has two structural forms: with and without leads (some also have a protection card for short circuit when overheating).
Glass-sealed discharge tube (product description) Micro surge absorber is an overvoltage protection device that suppresses abnormal high-voltage pulses and protects low-voltage circuits from damage by instantaneous high-voltage (such as lightning, high-voltage noise from the power grid, high-voltage static electricity, etc.) . It is a guided protection component developed using the principle of micro-gap discharge and the activation of semiconductor chips. It has the advantages of fast response, impact resistance, stable performance, good repeatability and long life.
A semiconductor discharge tube (also called a solid discharge tube) is a PNPN component, which is regarded as a free voltage-controlled thyristor without a gate electrode. When the voltage exceeds its off-state peak voltage (or avalanche voltage) When the semiconductor discharge occurs, the transient voltage will be clamped to within the switching voltage (or breakover voltage) value of the component. When the voltage continues to increase, the semiconductor discharge tube enters the conduction state due to the negative resistance effect. Only when the current is less than the holding current, the component resets and returns to its high impedance state.
