IS4N46 IS4N45 LOW INPUT CURRENT DARLINGTON OUTPUT OPTICALLY COUPLED ISOLATOR APPROVALS z UL recognised, File No. E91231 "JJ " 'X' SPECIFICATIONAPPROVALS z VDE 0884 in 3 available lead form : - STD - G form - SMD approved to CECC 00802 DESCRIPTION The IS4N45, IS4N46 are optically coupled isolators consisting of an infrared light emitting diode and a NPN silicon photo darlington which has an integral base-emitter resistor to optimise switching speed and elevated temperature characteristics in a standard 6pin dual in line plastic package. These devices are designed to equal the 4N45, 4N46 characteristics while providing greater voltage and current capability. z FEATURES z Options :10mm lead spread - add G after part no. Surface mount - add SM after part no. Tape&reel - add SMT&R after part no. z High Isolation Voltage (5.3kVRMS ,7.5kVPK ) z High Current Transfer Ratio ( 1500% typ.)
