78 axial transguard ? and staticguard avx axial multilayer ceramic transient voltage suppressors general description axial transguard ? multilayer varistors are zinc oxide (zno) based ceramic semiconductor devices with non-linear voltage-current characteristics (bi-directional) similar to back-to-back zener diodes. they have the added advantage of greater current and energy handling capabilities as well as emi/rfi attenuation. axial staticguard is low capacitance version of the transguard and are designed for general esd protection of cmos, bi-polar, and sige based systems. avx axial varistors are designed for applications where leaded component is prefered and for durability in harsh environment. va varistor axial how to order - axial transguard ? 1000 case size 1000 2000 18 voltage 03 = 3.3vdc 05 = 5.6vdc 14 = 14vdc 18 = 18vdc 26 = 26vdc 30 = 30vdc 48 = 48vdc 60 = 60vdc d energy rating a = 0.1j d = 0.4j k = 0.6j 400 clamping voltage 100 = 12v 150 = 18v 300 = 32v 400 = 42v 580 = 60v 650 = 67v 101 = 100v 121 = 120v r packaging d = 7" reel r = 7" reel t = 13" reel l termination l = ni/sn plated features ? axial leaded, epoxy encapsulated ? fast response ? emi/rfi filtering in the off-state ? multiple strikes capability applications ? white goods ? industrial equipment ? sensors ? relays ? dc motors ? and more general characteristics ? operating temperatures: -55oc to +125oc ? working voltage: 3.3 - 60vdc ? case size: axial ? energy: 0.1 - 2.0j ? peak current: 30 - 300a packaging (pcs/reel: style d r t va1000 1,000 3,000 7,500 va2000 1,000 2,500 5,000 va varistor axial how to order - axial staticguard 10 case size 10 = 1000 lc low capacitance 18 voltage 18 = 18vdc a energy rating a = 0.1j 500 clamping voltage 500 = 50v r packaging d = 7" reel r = 7" reel t = 13" reel l termination l = ni/sn plated
