The Littelfuse CG2470L is a gas discharge tube (GDT) from the CG2 series, designed for board-level surge protection. It provides a 470V nominal DC breakdown voltage and can handle impulse discharge currents up to 20kA (8/20µs) with a maximum single-pulse rating of 4kA (10/350µs). The device features a low capacitance of 1.5 pF typical, making it suitable for high-speed data lines. Its rugged ceramic-metal construction ensures reliability in harsh environments. The GDT is RoHS3 and lead-free compliant, and it meets UL 497B and UL 1449 standards (specific file numbers E1286621 and E3201162).
Key electrical characteristics include a minimum insulation resistance of 10 GΩ at 100V, an arc voltage of 15V minimum at 1A, and a minimum DC holdover voltage of 135V. The surge life is rated at 400 shots under 500A 10/1000µs conditions. The part is a two-pole design with through-hole mounting in an axial cylinder package.
Applications include communication lines, CATV equipment, data lines, power supplies, instrumentation circuits, medical electronics, ADSL equipment, and telecom SLIC protection. The CG2470L is a reliable choice for protecting sensitive electronics from transient overvoltages.
The DC breakdown voltage is 470V typical, with a minimum of 400V and maximum of 540V at 100V/s.
At 100V/µs the maximum impulse breakdown is 850V, and at 1kV/µs it is 1200V.
The typical capacitance is 1.5 pF at 1 MHz.
The surge life is a minimum of 400 shots at 500A 10/1000µs.
Yes, it is RoHS3 compliant and lead-free.
The package is an axial cylinder with through-hole mounting.
