Data Pairs (Pins 1+2 and 3+6): Data pairs are protected by an advanced hybrid circuit consisting of gas tubes coordinated with bridged, dual redundant, high capacity silicon avalanche diodes (SAD). Our solid state SAD design intercepts the leading edge of surges with sub-nanosecond response time, then gas tubes crowbar the surge to ground. Our unique solid state bridge SAD circuit design dramatically lowers effective capacitance, allowing much higher data rates than simple SAD circuits.

Non-Data Pairs (Pins 4+5 and 7+8): Robust dual redundant high-capacity metal oxide varistors (MOV) clamp surges with sub-nano second response time. Use of MOVs eliminates DC holding current problems found in other gas tube hybrid designs, allowing the use of our design on systems delivering higher power non current IEEE 802.3af limits.
