for the latest product information and datasheets schottky rectifier diodes the zhcs series diodes provide excellent high performance specifications in miniature surface mount packages. an optimized geometry / process with superior packaging gives an unmatched i f /v f performance and p d capability, enabling significant space savings, circuit efficiencies and cost effective solutions to larger package options. complementing the very low vf performance of the zhcs series zetex has introduced 4 new surface mount, high current, very low leakage, fast switching schottky diodes. these new low leakage diodes are ideally suited to applications requiring efficient operation at higher temperatures, often a significant limitation of conventional schottky types. the zlls series diodes are provided in a choice of packages which relate directly to die size and i f performance ensuring that designers have the optimum choice of package size / performance / cost. features v r 40v and 60v types low forward voltage high current capability fast recovery time miniature package size options very low v f at high temperature operation (above 85c) (zlls series) complement the existing range of zhcs series (optimized for operation at lower temperatures) zhcs types can be found in other products and solutions: mlp outline - www.zetex.com/3.0/combi.asp zxsc300/310/400 led driver solution and zsxc100/410/420 boost converter solution - www.zetex.com/led & www.zetex.com/zxsc100 applications forward and flyback converters mobile telecommunications, pcmcia (flashcards) and scsi lan psus distributed and auxiliary supplies high frequency rectification dc conversion (telecom dc modules) charging circuits motor control 24 www.zetex.com/schottky 24 24 24 schottky diodes part number v r i f i fsm v f at i r at capacitance at v r = 25v, f = 1mhz package max v max ma max a max mv i f ma max a v r v typ. pf zhcs2000 40 2000 20 500 2000 250 30 60 sot23-6 zhcs1000 40 1000 12 500 1000 100 30 25 sot23 zhcs750 40 750 12 540 750 100 30 25 sot23 zhcs500 40 500 6.75 550 500 40 30 20 sot23 zhcs400 40 400 6.75 500 400 40 30 20 sod323 zhcs1006 60 900 12 600 1000 100 45 17 sot23 zhcs756 60 750 12 610 750 100 45 17 sot23 zhcs506 60 500 5.5 630 500 40 45 20 sot23 part number v r i f v f at i r at 30v t rr c d p d package v a max mv ma ans pf w zlls2000 40 2.2 540 2000 40 3.71 65.0 1.1 sot23-6 zlls1000 40 1.16 560 1000 20 2.58 31.0 0.625 sot23 zlls500 40 0.7 530 500 10 2.46 15.5 0.5 sot23 zlls400 40 0.52 500 400 10 2.46 15.5 0.33 sod323 zlls series - low leakage schottky rectifier diodes zhcs series - schottky rectifier diodes connection diagrams single sod323 sot23 sot23-6
