Recent additions to the Bourns family of GDTs include the 2038 series, symmetrical mini GDT. This product is designed to provide symmetrical breakdown voltage across end-to-end as well as end-to-center electrodes. Typical three electrode GDTs exhibit a breakdown voltage from end-to-end that is nearly twice the voltage of end-to-center. The 2038 series provide superior board level protection with its enhanced protection characteristics and ultra-low capacitance of <1 pf. This series is offered with an extended voltage range of 150 to 1100 V. The 2039 series has been added to provide a higher voltage range for the mini, two element product. The 2039 is offered from 470 to 1100 V.
