Innovative Low-Profile Bourns 2015 Series Gas Discharge Tube Surge Arrestors Available From Mouser

MANSFIELD, Texas — Mouser Electronics, Inc. is now stocking the 2015-Series Gas Discharge Tube Surge Arrestors from Bourns. These new surge arrestors offer a conventional two‑electrode gas discharge tube surge arrestor, in an innovative flat package design. These coin‑shaped surge arrestors are 8mm in diameter and only 1.60mm in height.

The new Bourns 2015-Series Gas Discharge Tube Surge Arrestors, available from Mouser Electronics, are low profile surge arrestors used to protect compact, space limited systems that have very limited component height. Surge arrestors are placed in a circuit to protect electronics from spikes in current that can damage sensitive electronics equipment. When inactive, Bourns gas discharge tube (GDT) surge arrestors have an extremely high resistance that is greater than 1GΩ, making it virtually invisible to a circuit. However, when a current spike greater than the GDT's sparkover value is applied across its two terminals, the gas inside a Bourns GDT quickly ionizes, called “arc mode”, transitioning the GDT from very high resistance to a virtual short circuit. The surge current can then be safely diverted away from sensitive electronics.

The Bourns 2015‑Series GDT's are available with sparkover values of 90V, 150V, 230V, and 350V and can transition to arc mode in as fast as 20 µsec. These surge arrestors maintain a constant capacitance of as little as 1.9pF over voltage. The Bourns 2015‑Series GDT surge arrestors target space limited, high performance applications and complies with ITU‑K.12 Class II safety standards. These GDTs are engineered to protect sensitive electronic equipment from surges under harsh environments including temperatures ranging from ‑55 to +85°C.
