| E2P0066-37-X2 OPTICAL MOS RELAYS This version: Jan. 1998 Previous version: May. 1997 OCMS2M6DP Series M electronic components OCMS2M6DP SERIES M Power Saving Dial Pulse SOP Type Optical MOS Relay For AC/DC Load GENERAL DESCRIPTION The OCMS2M6DP series is a family of optical MOS relays for AC/DC load. 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 SOP type package. The series reduced its area to 50% and its volume to 27% of the conventional DIP or SMD-type optical MOS relays. The series is 2.1mm thick and is ideal for modem card applications. 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 curcuit 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 Thickness of 2.1mm 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 SOP package) APPLICATIONS * * * * * * Telecommunications system (such as modem cards) 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 OCMS2M6DP Series M PIN CONFIGURATION (Unit: mm) * 6pin SOP Type 6.3 0.3 0.4 0.1 y r 6.4 0.4 4.4 0.3 5.72 1.0 0.25 * Mounting pad (Top view) 0.76 1.27 2.0 0.25 q 2.54 0.1 5.08 e 0.15 +0.10 -0.05 0.12 0~10 0.5 0.2 5.72 * Pin Connection Diagram 2.54 2.54 y t r Discharge Circuit 1: Anode 2: Cathode 3: NC 4: Drain 5: Source 6: Drain (LED) (LED) (MOS FET) (MOS FET) (MOS FET) q w e 0.15 +0.2 -0.1 2/7 OPTICAL MOS RELAYS OCMS2M6DP Series 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 OCMS236DP 50 OCMS246DP 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 75 350 140* 400 120* Peak Forward Current IFM Reverse Voltage Power Dissipation Load Voltage Load Current Derating Factor of Load Current Surge Load Current Power Dissipation Isolation Voltage Storage Temperature VR PDL VOFF ION DION ISUG PD VIO Tstg A V mW V mA mA/C Output Characteristics Refer to [Derating Factor of Load Current] of characteristics data 0.8 300 325 1500 -40 to +85 -40 to +100 0.7 Pulse width 1 ms 1shot A mW mW V(rms) C C Total Power Dissipation Ptot Operating Temperature Topr * : Load current when mounted on a board.
