La protection unidirectionnelle est g\u00e9n\u00e9ralement pr\u00e9f\u00e9rable \u00e0 la bidirectionnelle, en particulier sur des lignes logiques et de transfert de donn\u00e9es qui ne font normalement pas transiter z\u00e9ro volt au cours d\u2019op\u00e9rations standard.<\/p>\n

Con\u00e7ues sur la base d\u2019une technologie \u00e0 semi-conducteurs \u00e0 action rapide, les barrettes de diodes TVS s\u00e9rie SP3145 (SPA Diodes) peuvent r\u00e9sister \u00e0 des d\u00e9charges \u00e9lectrostatiques (DES) multiples sans usure ni dommage. Leur basse capacitance nominale de 0.35 pF en fait des composants particuli\u00e8rement bien adapt\u00e9s pour des interfaces fonctionnant \u00e0 haut d\u00e9bit de donn\u00e9es et qui approchent des fr\u00e9quences d\u2019horloge de 5 GHz.<\/p>\n

D\u2019utilisation g\u00e9n\u00e9rale, les barrettes de diodes TVS s\u00e9ries SP1043 de 8 pF et SP1044 de 30 pF font appel \u00e0 la technologie propri\u00e9taire \u00e0 avalanche au silicium pour prot\u00e9ger les ports E\/S d\u2019\u00e9quipements \u00e9lectroniques pouvant \u00eatre soumis \u00e0 des DES destructrices. Ces robustes diodes peuvent absorber en toute s\u00e9curit\u00e9 des DES r\u00e9p\u00e9t\u00e9es \u00e0 \u00b112 kV pour les versions 8 pF ou \u00b130 kV pour les 30 pF sans d\u00e9gradation de leur performance.
\nCes deux s\u00e9ries sont g\u00e9n\u00e9ralement utilis\u00e9es dans les smartphones, appareils photos num\u00e9riques, technologie portable, tablettes et autres appareils portables.<\/p>\n

Selon Tim Micun, responsable monde pour les barrettes de diodes TVS (SPA Diodes) chez Littelfuse, \u00ab\u00a0pour les concepteurs des actuelles cartes de circuits imprim\u00e9s toujours plus pl\u00e9thoriques, l\u2019empreinte ultra compacte de ces nouvelles barrettes de diodes TVS permet \u00e0 la fois de lib\u00e9rer de l\u2019espace sur les cartes et d\u2019\u00e9conomiser sur les co\u00fbts.\u00a0\u00bb<\/p>\n

\n

Parmi les avantages cl\u00e9, ces composants fournissent une protection unidirectionnelle basse capacitance contre les DES dans la plus petite empreinte du secteur industriel pour garantir l\u2019int\u00e9grit\u00e9 des donn\u00e9es tout en \u00e9conomisant de l\u2019espace sur les cartes PCB. Ils conf\u00e8rent une r\u00e9sistance totale aux DES au-del\u00e0 de la charge maximale admise par la norme IEC61000-4- 2 pour offrir aux concepteurs de circuits imprim\u00e9s une plus grande marge de conception et une meilleure fiabilit\u00e9 du produit final dans ce domaine.
\nLa faible r\u00e9sistance dynamique de 3.5 ohms max. pour la SP3145 et de 0.45 ohms max. pour les deux autres s\u00e9ries contribue \u00e0 assurer la tension limite n\u00e9cessaire \u00e0 la protection de l\u2019\u00e9lectronique moderne bourr\u00e9e de circuits int\u00e9gr\u00e9s de petite dimension. La basse tension d\u2019avalanche de 6 V max. pour les SP1043\/SP1044 et de 3.3 V max. pour la SP3145 permet de prot\u00e9ger jusqu\u2019\u00e0 95% de toutes les interfaces.<\/p>\n

Ces trois s\u00e9ries sont propos\u00e9es par 15.000 unit\u00e9s sous forme de bandes sur bobines.<\/p>\n
