| E2P0046-37-X4 OPTICAL MOS RELAYS This version: Jan. 1998 Previous version: May. 1997 OCM1M4, 1M5 Series M M electronic components OCM1M4, 1M5 SERIES M M Low Output-capacitance Type Optical MOS Relay For DC Load Only GENERAL DESCRIPTION The OCM1M4 and OCM1M5 Series are optical MOS relays for DC load only that provide highspeed response and are capable of handling high-frequency signals. The input portion is an infrared light emitting diode. The output portion uses a combination of low-capacitance VDMOS (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 Excellent high-frequency characteristics (>30 dB isolation at 10 MHz) High-speed response (tON and tOFF is 200 ms or less) Low leak current No chattering or swich bounces No mechanical switching noises Small size and easy mounting (6-Pin plastic DIP or SMD-type [gull-wing] package) APPLICATIONS * * * * * * Measurement equipment Audio-visual 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 OCM1M4, 1M5 Series M M PIN CONFIGURATION (Unit: mm) * DIP Type 8.68 0.5 y r 7.62 0.15 0.25 0.03 6.4 0.3 0 +15 -0 * SMD Type (gull-wing) 5.68 0.25 y 8.680.5 1.20.2 r 6.4 0.3 0.6 1.1 0.4 1.2 0.2 q 2.54 0.1 5.08 e 5.93 0.25 3.65 0.2 MAX 0 +15 -0 q 2.54 0.1 5.08 e 0.25 0.03 4.75 3.65 0.2 0.8 0.2 2.8 0.35 0.5 0.2 0.5 0.2 * Through hole (Bottom view) * Mounting pad (Top view) 1.5 1.9 4.0 0.2 6-f0.85 2.54 2.54 7.62 8.3 * Pin Connection Diagram y t r Discharge Circuit 1: Anode 2: Cathode 3: NC 4: Drain 5: Source 6: Source (LED) (LED) (MOS FET) (MOS FET) (MOS FET) q w e 2.54 2.54 1.1 0.4 9.9 2/7 OPTICAL MOS RELAYS OCM1M4, 1M5 Series M M ABSOLUTE MAXIMUM RATINGS (Ambient temperature Ta=25C) Product Name Parameter Symbol OCM104 OCM114 OCM124 OCM144 Condition Unit OCM105 OCM115 OCM125 OCM145 mA mA/C 50 Refer to [Derating Factor of Continuous Forward Current] of characteristics data 0.5 5 75 60 100 100 70 200 50 400 20 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 10 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 0.1 300 325 1500 OCM104 OCM114 OCM124 OCM144 4000 OCM105 OCM115 OCM125 OCM145 -40 to +85 -40 to +100 0.07 0.025 Isolation Voltage VIO V(rms) Operating Temperature Storage Temperature Topr Tstg C C 3/7 OPTICAL MOS RELAYS OCM1M4, 1M5 Series M M ELECTRICAL CHARACTERISTICS (Ambient temperature Ta=25C) Product Name Parameter Input Characteristics Symbol OCM104 OCM114 OCM124 OCM144 Condition IF=10 mA VR=5 V ION=Rating VOFF=Rating ION=100 mA IF=10 mA ION=100 mA Time to flow current is within one second Unit OCM105 OCM115 OCM125 OCM145 V mA mA mA 10 W nA pF pF ms ms 15 20 20 32.5 45 1.0 7 1.3 30 200 60 200 1.0 1.3 10 5 0.2 50 75 100 150 300 450 Forward Voltage Reverse Current Input Current Input Current VF IR *1 IFA Min.
