SE Series - Ultra-small square GDT high surge current withstand patch gas discharge tube


SE series GDT offers high surge ratings in a miniature package. It’s designed for surface mounting on PCB with small size 3.2x1.6x1.6mm. 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 500A-600A pulse in a miniature package 1206 without destruction.




• RoHS compliant and Lead-free

• GHz working frequency

• Excellent stability on multiple pulse duty cycle

• Excellent response to fast rising transients.

• Ultra Low Insertion Loss

• 0.5-0.6KA surge capability tested with 8/20μS pulse as defined by IEC 61000-4-5

• Ultra small devices offered in a variety of mounting lead forms

• Non-Radioactive

• Low capacitance (<0.5pF)

• Voltage Ranges 140V to 500V

• UL recognized

• Conforms to ITU-T K12, IEC 1000-4-5

• Square Outline




• Communication equipment

• CATV equipment

• Test equipment

• Data lines

• Power supplies

• Telecom SLIC protection

• Broadband equipment

• ADSL equipment, including ADSL2+

• XDSL equipment
