Bourns Introduces New High Voltage Gas Discharge Tube Arrestor for Power Applications – Model GDT25H.
Bourns, a leading manufacturer and supplier of circuit protection solutions, announces the release of its new two-electrode high voltage Gas Discharge Tube (GDT) arrestor, model GDT25H, designed for use in power and industrial surge protection applications.
The GDT25H series is developed to support surge protective device designs that must comply with UL 1449, giving engineers a robust and flexible option that goes beyond traditional UL 497B telecom classifications.
Engineered for High Voltage Surge Protection
The Bourns GDT25H model is tailored for high voltage environments where reliable overvoltage protection is critical, such as AC and DC power systems, industrial controls, and energy infrastructure.
With its compact two-electrode construction, the device can be easily integrated into modern PCB-based surge protection circuits while helping protect sensitive downstream components from damaging transient events.
Key Features and Benefits
- High voltage rating suitable for power line and industrial surge protection applications.
- Two-electrode GDT design for compact and straightforward implementation in surge protection topologies.
- Designed to support UL 1449 surge protective device requirements, complementing existing Bourns GDT and MOV portfolios.
- Helps provide isolation in normal operating conditions and low residual voltage during surge events.
- Engineered for long-term reliability in demanding operating environments.
