| E2P0067-37-X2 OPTICAL MOS RELAYS This version: Jan. 1998 Previous version: May. 1997 OCM2M6LD, 2M7LD Series M M electronic components OCM2M6LD, 2M7LD SERIES M M Power Saving General-purpose Type Optical MOS Relay For AC/DC Load GENERAL DESCRIPTION The OCM2M6LD and OCM2M7LD Series are optical MOS relays for AC/DC load that are lower in cost than the OCM2M0/2M1 Series. 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 * * * * * Extremely low voltage control High reliability due to non-contact, 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 OCM2M6LD, 2M7LD 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 9.9 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 e 0.25 0.03 5.08 3.65 0.2 0.2 4.75 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 4.0 1.9 6-f0.85 2.54 2.54 7.62 * Pin Connection Diagram 8.3 1: Anode 2: Cathode 3: NC 4: Drain 5: Source 6: Drain (LED) (LED) (MOS FET) (MOS FET) (MOS FET) y t r Discharge Circuit q w e 2.54 2.54 1.1 0.4 2/7 OPTICAL MOS RELAYS OCM2M6LD, 2M7LD Series M M ABSOLUTE MAXIMUM RATINGS (Ambient temperature Ta=25C) Product Name Parameter Input Characteristics Derating Factor of Continuous Forward Current Symbol Condition Unit mA mA/C OCM206LD OCM236LD OCM237LD 50 OCM246LD OCM247LD Continuous Forward Current IF DIF Pulse width 100 ms Cycle 10 ms Refer to [Derating Factor of Continuous Forward Current] of characteristics data 0.5 5 75 60 350 400 120 140 350 Refer to [Derating Factor of Load Current] of characteristics data 1.0 0.8 300 325 1500 OCM206LD -- OCM236LD 4000 OCM237LD -40 to +85 -40 to +100 OCM247LD OCM246LD 0.7 Peak Forward Current IFM Reverse Voltage Power Dissipation Load Voltage Load Current Derating Factor of Load Current Surge Load Current Power Dissipation VR PDL VOFF ION DION ISUG PD A V mW V mA mA/C Output Characteristics Pulse width 1 ms 1shot A mW mW Total Power Dissipation Ptot Isolation Voltage VIO V(rms) Operating Temperature Topr Storage Temperature Tstg C C 3/7 OPTICAL MOS RELAYS OCM2M6LD, 2M7LD Series M M ELECTRICAL CHARACTERISTICS (Ambient temperature Ta=25C) Product Name Parameter Symbol Condition IF=10 mA VR=5 V VOFF=Rating ION=100 mA IF=10 mA ION=Rating Time to flow current is within one second Unit V OCM206LD OCM236LD OCM237LD 1.0 1.3 10 0.5 0.02 OCM246LD OCM247LD Input Characteristics Forward Voltage Reverse Current Operation Input Current VF IR IFA Min.
