Bourns Releases New High Energy GDTs

Aggiornamento: 16 ott 2023

Model GDT212E, GDT216E, GDT220E and GDT225E Series


PRODUCT GROUP: Gas Discharge Tubes

 

Riverside, CaliforniaSeptember 22, 2023 – Bourns is pleased to announce the release of four new high energy GDT series – the Model GDT212E, GDT216E , GDT220E and GDT225E.


These new high energy models are tested per ITU-T K.12 method and are UL recognized GDT devices. They offer a high surge capability rated on an 8/20 μs waveform with a broad range of DC breakdown voltages as

shown in the table below.

BENEFITS


  • Very high current handling capability for AC power line applications in a small footprint

  • Broad range of DC breakdown voltage and lead shapes to fit different configuration requirements

  • Innovative low profile package provides a volume and space-saving solution for high density and space-restricted PCB applications

  • Offers lower clamping voltage than MOVs for the same surge current rating

  • GDTs have a longer lifespan than other types of surge arrestors, and can withstand more surge events without degradation
