March 2, 2026 - Bourns, a globally renowned leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, 

has launched the GDT225HE series of high-voltage, high-energy gas discharge tubes (GDT) lightning arresters. With industry-leading surge protection 

performance in a compact size, Bourns' new GDT products have been optimally designed for high-energy AC-DC power systems, including electric 

vehicle charging infrastructure, battery energy storage systems (BESS), and industrial power conversion equipment. These systems are particularly 

prone to communication disruptions or fault insertion events. This series can safely withstand long-term high thermal energy (I²t) under transient 

conditions, making it highly suitable for system-level surge and fault protection, equipotential connection, and designs requiring safe current 

diversion and control of high-energy discharges in high-risk lightning scenarios. 

Bourns® GDT225HE Series High-Voltage, High-Energy Gas Discharge Tube     Arresters

The Bourns® GDT225HE series features a wide range of DC breakdown voltage (DCBV) (1000 to 2000 V), with a rated discharge current In of 40 kA 

(nominal discharge current) under the 8/20 μs waveform, and a maximum discharge current Imax of 60 kA. It provides outstanding protection 

performance for high-energy and lightning-prone applications. This high-power GDT is designed with a small, low-profile, and compact package, 

offering extremely high current carrying capacity and serving as a space-saving alternative to traditional large surge protection solutions, particularly 

suitable for AC power line applications. 

To assist design engineers in meeting the current demands for high-density and space-constrained PCB designs, this new series also offers a variety 

of different pin configurations to accommodate various specifications.
