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.

Gas Discharge Tube (GDT) is a three-pole discharge device that provides reliable circuit protection for lightning and surge protection. It features a fast response time of 1kv/μs, a surge current of 8x10mm, and a DC spark over voltage of 230v (100v/s). GDTs are widely used in many industrial and commercial applications, such as telecommunications, power supply, and surge suppression. The three-pole discharge tube is able to effectively and quickly dissipate large current surges by releasing the stored energy during an overvoltage event. This ensures the safety and reliability of the power system and helps extend the service life of the GDT.
