44 ultraguard series esd protection for low leakage requirements faster semiconductor clock speeds and an increasing reliance on batteries as power sources have resulted in the need for varistors that exhibit very low leakage current. the ultraguard (ug) series of avx transient voltage suppressors address this problem. the ug series is the ideal transient protection solution for high clock speed integrated circuit application, battery-operated device, backlit display, medical/instrument applica- tion, low voltage power conversion circuits and power supervisory chip sets. in addi- tion, ultraguards low leakage characteristics are also suitable for optic circuits like ldd, serdes, and laser diodes. the ug series is offered as discrete chips (0402, 0603, and 0805), 2-element pack- ages (0405 and 0508), and 4-element packages (0612). general description discrete chips 2-element arrays 4-element arrays 0402, 0603, (0405 and 0508) (0612) and 0805 p termination finish p = ni/sn alloy (plated) vc vc=surface mount chip ug series ug = low leakage series 04 case size 04 = 0402 06 = 0603 08 = 0805 0180 maximum working voltage 0030 = 3.0v dc 0050 = 5.0v dc 0075 = 7.5v dc 0100 = 10.0v dc 0150 = 15.0v dc 0180 = 18.0v dc l capacitance l = low h = high 1 no. of elements w packaging (pieces per reel) d = 1,000 (7" reel) r = 4,000 (7" reel) t = 10,000 (13" reel) w = 10,000 (7" reel, 0402 only) how to order p termination finish p = ni/sn alloy (plated) mg mg=array ug series ug = low leakage series 06 case size 04 = 0405 05 = 0508 06 = 0612 0150 maximum working voltage 0030 = 3.0v dc 0050 = 5.0v dc 0075 = 7.5v dc 0100 = 10.0v dc 0150 = 15.0v dc l capacitance l = low h = high 4 no. of elements 2 = 2 elements 4 = 4 elements d packaging (pieces per reel) d = 1,000 (7" reel) r = 4,000 (7" reel) t = 10,000 (13" reel) how to order
