GDTs operate in harsh environments

Bourns, Inc. has expanded its series of high-voltage gas discharge tubes (GDTs) with the launch of Model SA2-A GDTs. This new AEC-Q200-compliant GDT series meets the demands of certain harsh-environment applications that require high reliability, durability and adherence to regulatory standards.

These protection devices meet the need for advanced surge protection, addressing the evolving requirements of multiple market applications. The Model SA2-A Series has been evaluated under the AEC-Q200 standard to supply “superior” electrical performance, Bourns said. These capabilities make the Model SA2-A Series suited for high-voltage surge protection in a variety of harsh-environment designs, such as EV charging stations, industrial controls, photovoltaic installations, HVAC and power supplies. The new GDTs are also suited for “Protective Earth” (PE) isolation as required by IEC 62368-1 compliant equipment.

The Model SA2-A Series features breakdown voltages from 3,000 V to 7,200 V and a wide operating temperature range of -40°C to 125°C. Claiming exceptional energy dissipation and high insulation resistance, these high-voltage GDTs are designed to handle and dissipate high-energy surges, protecting sensitive electronic systems from damaging voltage spikes. They also provide highly reliable surge protection throughout the device’s lifecycle, Bourns said, minimizing maintenance needs and extending the intervals between replacement.

The two-electrode AEC-Q200-compliant GDTs are available now. They are RoHS compliant and UL recognized.
