Ces circuits très couramment utilisés sont devenus des choix évidents dans des applications à forte densité de composants, depuis les contrôleurs programmables et les modules AC\/DC jusqu’aux dispositifs télécoms et aux équipements bureautiques. Compatible au niveau du brochage comme de la fonctionnalité avec leurs prédécesseurs, ces coupleurs "mini-flat"  présentent une hauteur maximale de seulement 2,3 mm. Ils offrent la même tension d’isolation minimale (BVs) de 3750 Vrms mais affichent une tension d’isolation de pointe plus élevée (UIORM) de 707 V.
\nCes photo coupleurs ont été conçus pour opérer sur une gamme de températures étendues de -55 ºC à 110 ºC et affichent des tensions collecteur-émetteur minimales de 80 V. Le TLP184 peut opérer directement à partir d’une entrée AC et est spécifié pour un courant direct maximum de ±50 mA. Le courant direct maximum pour le TLP185 est de 50 mA. Les valeurs de courant direct maximum par impulsions sont respectivement ±1 A et 1 A.
\nCes deux composants sont construits autour d’un photo transistor couplé optiquement à une diode électroluminescente (DEL) infrarouge en GaAs. Dans le cas du TLP184, une connexion parallèle inverse supporte l’entrée AC.<\/p>\n
