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.

Series	DC Breakdown Voltage	Voltage Types	Maximum Impulse Discharge Current (8/20 µs) / Imax (1 Time)	Maximum Impulse Discharge Current (8/20 µs) / In (10 Times)
GDT212E	230 V to 800 V	10	40 kA	30 kA
GDT216E	500 V to 800 V	3	40 kA	20 kA
GDT220E	150 V to 1000 V	11	60 kA	40 kA
GDT225E	500 V to 800 V	3	80 kA	60 kA

The new GDT2xxE Series feature an innovative low profile, providing a volume and space-saving solution for high density and space-restricted PCB applications. This device is available in a variety of lead shapes to fit various configuration requirements.

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:

GDT212E

The Model GDT212E (12 mm diameter) Series is rated at 40 kA maximum on an 8/20 μs waveform. It features DC breakdown voltages from 230 V to 800 V.

GDT216E

The Model GDT216E (16 mm diameter) Series is rated at 40 kA maximum on an 8/20 μs waveform with DC breakdown voltages from 500 V to 800 V.

GDT220E

The Model GDT220E (20 mm diameter) Series is rated at 60 kA maximum on an 8/20 μs waveform. This series offers DC breakdown voltages from 150 V to 1000 V.

GDT225E

The Model GDT225E (25 mm diameter) Series is rated at 80 kA maximum on an 8/20 μs waveform. It features DC breakdown voltages from 500 V to 800 V.

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
