OCM1M4, 1M5 SERIES
OPTICAL MOS RELAYS
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 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.
