| E2P0045-37-X3 OPTICAL MOS RELAYS This version: Jan. 1998 Previous version: May. 1997 OCM1M2, 1M3 Series M M electronic components OCM1M2, 1M3 SERIES M M Low ON-resistance Type Optical MOS Relay For DC Load Only GENERAL DESCRIPTION The OCM1M2 and OCM1M3 Series are optical MOS relays for DC load only. The input portion is an infrared light emitting diode. The output portion uses a combination of VD-MOS (Vertical Diffusion MOS) FETs and photodiode arrays. The device is encased in an extremely small 6-pin plastic DIP or SMD-type (gull-wing) package. The optical MOS relay switch may be used in applications that currently use mechanical relay switches, but offers smaller size, noise-free switching, and electronic circuit compatibility because of its non-mechanical operation. Optical MOS relay switches also dissipate less power than equivalent bipolar devices at lower switching frequencies. FEATURES * * * * * Infinitesimally small control voltage High reliability due to non-contact and optical operation No chattering or switch bounces No mechanical switching noises Small size and easy mounting (6-pin plastic DIP or SMD-type [gull-wing] package) APPLICATIONS * * * * * * Telecommunications equipment Measurement equipment Home electronics Automatic meter reading equipment Other applications requiring small size or high performance Other applications requiring non-contact switches 1/7 OPTICAL MOS RELAYS OCM1M2, 1M3 Series M M PIN CONFIGURATION (Unit: mm) * DIP Type 8.68 y 0.5 * SMD Type (gull-wing) 5.68 0.25 r 8.680.5 0 +15 -0 1.20.2 y r 7.62 0.15 0.25 0.03 6.4 0.3 6.4 0.3 1.1 0.4 e 0.25 0.03 1.2 0.2 q 2.54 0.1 5.08 e 5.93 0.25 0 +15 -0 q 2.54 0.1 3.65 0.2 MAX 4.75 5.08 3.65 0.2 0.8 0.2 2.8 0.35 0.5 0.2 * Through hole (Bottom view) 0.5 0.2 * Mounting pad (Top view) 1.5 1.9 2.54 2.54 4.0 0.2 6-f0.85 7.62 8.3 * Pin Connection Diagram y t r 1: Anode 2: Cathode 3: NC 4: Drain 5: Source 6: Source (LED) (LED) (MOS FET) (MOS FET) (MOS FET) Discharge Circuit q w e 2.54 2.54 1.1 0.4 9.9 0.6 2/7 OPTICAL MOS RELAYS OCM1M2, 1M3 Series M M ABSOLUTE MAXIMUM RATINGS (Ambient temperature Ta=25C) Product Name Parameter Symbol OCM102 OCM112 OCM122 OCM142 Condition Unit OCM103 OCM113 OCM123 OCM143 mA mA/C 50 Refer to [Derating Factor of Continuous Forward Current] of characteristics data 0.5 5 75 60 500 100 450 200 350 400 200 Input Characteristics Continuous Forward Current IF Derating Factor of Continuous Forward Current Peak Forward Current Reverse Voltage Power Dissipation Load Voltage Load Current Derating Factor of Load Current Surge Load Current Power Dissipation Total Power Dissipation DIF IFM VR PDL VOFF ION DION ISUG PD Ptot Pulse width 1 ms 1shot Pulse width 100 ms Cycle 10 ms A V mW V mA mA/C A mW mW Output Characteristics Refer to [Derating Factor of Load Current] of characteristics data 3.5 300 325 1500 OCM102 OCM112 OCM122 OCM142 4000 OCM103 OCM113 OCM123 OCM143 -40 to +85 -40 to +100 1.5 Isolation Voltage VIO V(rms) Operating Temperature Storage Temperature Topr Tstg C C 3/7 OPTICAL MOS RELAYS OCM1M2, 1M3 Series M M ELECTRICAL CHARACTERISTICS (Ambient temperature Ta=25C) Product Name Parameter Input Characteristics Forward Voltage Symbol OCM102 OCM112 OCM122 OCM142 Condition IF=10 mA VR=5 V ION=100 mA VOFF=Rating ION=100 mA IF=10 mA ION=100 mA Time to flow current is within one second Unit OCM103 OCM113 OCM123 OCM143 V mA mA mA 0.2 W mA pF pF ms ms 70 50 1.3 0.3 1.0 0.2 1.0 0.5 0.75 0.3 0.7 1.0 1.0 35 25 1.0 1.3 10 5 0.2 1.0 1.5 2.0 3.0 4.5 6.2 VF Min.
