| E2P0043-37-X2 PHOTOCOUPLERS This version: Jan. 1998 Previous version: May. 1997 OCS40 electronic components OCS40 Optical PNPN Switches with OFF Function GENERAL DESCRIPTION The OCS40 adds an OFF function to the standard optical PNPN switch to provide an optically controlled ON-OFF function. In addition to standard latch functions, the OCS40 also offers a pulse- drive-controlled ON-OFF capability. FEATURES * * * * ON-OFF control using pulse Low drive current (IGON, IGOFF : 10 mA Max.) High blocking voltage (VBO, VBD : 350 V Min.) Total I/O isolation APPLICATIONS * * * * * * Electronic automatic exchange Key telephone system Home electronics Measuring instrument Substitute for latching relay Optically coupled circuits PIN CONFIGURATION (Unit: mm) 8.68 0.5 0.85 0.2 8 * Pin Connection Diagram 1.2 0.2 5 5.68 0.25 K A 7 6 5 0 +15 -0 8 7.62 0.15 6.4 0.3 0.25 0.03 1 2 3 4 K 1 4 A K 2.54 0.1 7.62 5.93 0.25 0 +15 -0 0.5 0.2 0.5 0.2 1: NC (No connection) 2: OFF Cathode (LED) 3: ON, OFF Anode (LED) 4: ON Cathode (LED) 5: PNPN Anode 6: NC (No connection) 7: PIN cut 8: PNPN Cathode 3.65 0.2 0.8 0.2 2.8 0.35 4.75 max. 1/3 PHOTOCOUPLERS OCS40 ABSOLUTE MAXIMUM RATINGS Parameter Input (LED) Forward Current Reverse Voltage Forward Blocking Current Output (PNPN) Reverse Voltage Continuous ON-State Current Surge ON-State Current * Isolation Voltage Operating Temperature Storage Temperature * A single 1 ms pulse Symbol IG VRL VBO VBD IF ISUG Vin-out Topr Tstg -- -- Ta=25C Test Condition Rating 60 5 350 350 100 1.4 1500 -20 to +70 -55 to +125 Unit mA V V V mA A V C C ELECTRICAL CHARACTERISTICS Parameter Input Characteristics (Ambient Temperature Ta=25C) Test Condition IG=40 mA VRL=5 V VBD=320 V VBD=320 V IF=20 mA, IG=40 mA -- IGOFF=0.25 mA ON to OFF VAK=50 V VAK=50 V, IGOFF=0.35 mA IF=100 mA Min. -- -- -- -- -- 80 210 -- -- -- -- Typ. -- -- -- -- -- -- -- -- -- -- -- Max.
