Gas Discharge Tube 150 V 2000A (2kA) 2 Pole Surface Mount
Active730 in stock
Overview
The SG150 is a 2-pole surface mount Gas Discharge Tube (GDT) designed to protect sensitive electronic equipment from transient voltage surges. This component provides high-current handling capability up to 2000A (2kA) in a compact 1812 (4532 Metric) footprint, making it ideal for high-density circuit protection. It features a nominal DC spark-over voltage of 150V and operates without a fail-short mechanism.
Why Choose This Part
The 1812 surface-mount package allows for automated assembly and space savings compared to leaded GDTs. With a 2000A impulse discharge current rating, it offers robust protection against high-energy transients despite its small physical size.
Applications
Telecommunications Equipment
Protection of broadband lines and communication interfaces from lightning induced surges.
Industrial Control Systems
Shielding sensitive PLC inputs and industrial sensor loops from high-energy transients.
Power Supply Input Protection
Used as a primary protection stage to clamp overvoltage events before they reach downstream regulators.
