4N33

4N32/4N33 PHOTODARLINGTON OPTOCOUPLER FEATURES Very High Current Transfer Ratio, 500% Min. High Isolation Resistance, 1011 Ω Typical Standard Plastic DIP Package Underwriters Lab File #E52744 V VDE Approvals #0884 (Available with Option 1) D E Dimensions in inches (mm) Pin One ID. 3 .248 (6.30) .256 (6.50) 4 5 6 2 1 Anode 1 Cathode 2 NC 3 6 Base 5 Collector 4 Emitter DESCRIPTION The 4N32 and 4N33 are optically coupled isolators with a Gallium Arsenide infrared LED and a silicon photodarlington sensor. Switching can be achieved while maintaining a high degree of isolation between driving and load circuits. These optocouplers can be used to replace reed and mercury relays with advantages of long life, high speed switching and elimination of magnetic fields.
