Model GDT212E, GDT216E, GDT220E and GDT225E Series
PRODUCT GROUP: Gas Discharge Tubes
Riverside, California – September 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.
DC Breakdown Voltage
Maximum Impulse Discharge Current (8/20 µs) / Imax (1 Time)
Maximum Impulse Discharge Current (8/20 µs) / In (10 Times)
230 V to 800 V
500 V to 800 V
150 V to 1000 V
500 V to 800 V

Stable performance throughout life
Small surface mount package
Surge Protective Devices (SPDs)
INTRODUCTION & DETAILS for EACH MODEL
Bourns' new High Energy Gas Discharge Tube (GDT) surge arrestor family is designed for AC power line and other high current applications. These high surge current-rated 2-electrode GDTs deliver high performance protection in an innovative low profile package. The new family includes four series that meet international IEC lightning protection zone, UL1449, and IEC 61643-11 standards, and are suitable for Class I, II and III surge protection. Read along for more details for each model:
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
Test Methods per ITU-T K.12, IEEE C62.31 and IEC 61643-311 GDT Standards
