3 Series
Low ON-resistance Type Optical MOS Relay For DC Load Only
GENERAL DESCRIPTION
The OCM1
M
2 and OCM1
M
3 Series are optical MOS relays for DC load only. 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
Infinitesimally small control voltage
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 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
