OCM1M4, 1M5 SERIES
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 high-
speed 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 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
• 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
