GTCA28-152L-R03 is a gas discharge tube (GDT) from Littelfuse Inc. designed for overvoltage protection in sensitive electronic equipment. It has a nominal DC sparkover voltage of 1500V with a tolerance of ±15% and can handle impulse discharge currents up to 3kA (8/20μs waveform). The device features two poles and is housed in an axial cylinder package with through-hole mounting.
GDTs are crowbar devices that switch to a low impedance state during an overvoltage surge, diverting energy away from protected circuits. This model does not include a fail-short mechanism. It is RoHS compliant and halogen free as per the manufacturer's specifications.
Typical applications include main distribution frame (MDF) modules, high data-rate telecom systems (e.g., ADSL, VDSL), and surge protection on power lines. The low capacitance of GDTs minimizes signal distortion in high-frequency applications.
The axial cylinder package allows for easy through-hole mounting on printed circuit boards. The device is tested per ITU K.12 recommendations and is certified to UL497B and UL144 standards.
