Littelfuse SG series GDT offers high surge ratings in a miniature package. It's designed for surface mounting on PCB with small size 4.5x3.2x2.7mm. Low insertion loss is perfectly suited to broadband equipment applications.
The capacitance does not vary with voltage, and will not cause operational problems with ADSL2+, where capacitance variation across Tip and Ring is undesirable. These devices are extremely robust and are able to divert a 1000A pulse without destruction.
Lead-free and RoHS compliant
GHz working frequency
Excellent stability on multiple pulse duty cycle
Excellent response to fast rising transients
Ultra-low Insertion Loss
1-2 kA surge capability tested with 8/20 uS pulse as defined by IEC 8100-4-5
Ultra-small devices offered in a variety of mounting lead forms
