Providing industry-leading surge protection performance in a compact package, Bourns new GDTs are optimized for high-energy AC-DC power systems, including EV charging infrastructure, Battery Energy Storage Systems (BESS) and industrial power conversion equipment.

These systems, in particular, are known to experience commutation or fault insertion events. It is the series’ ability to safely conduct prolonged high thermal (I²t) energy during transient conditions that makes it well-suited for system-level surge and fault protection, equipotential bonding and for lightning-prone designs where high-energy discharge must be safely diverted and controlled.

The Bourns GDT225HE Series features a broad DC Breakdown Voltage (DCBV) from 1000 to 2000 V, I_n 40 kA (Nominal Discharge Current) and I_max 60 kA (Maximum Discharge Current) ratings on an 8/20 μs waveform to deliver exceptional protection for lightning-prone and high-energy applications. These high-power GDTs provide a space-saving alternative to bulky surge protection solutions by delivering very high current handling capabilities for AC power line applications in a small low-profile, reduced-volume and space-saving footprint. To help designers satisfy the requirements in today’s high-density and space-constrained PCB-based designs, this new series is also available in various lead shapes to fit in different configuration specifications.
