FEATURES
1. Controls low-level analog signals
PhotoMOS relays feature extremely low
closed-circuit offset voltage to enable
control of low-level analog signals without
distortion.
2. Control with low-level input signals
3. Controls various types of loads such
as relays, motors, lamps and sole-
noids.
4. Optical coupling for extremely high
isolation
Unlike mechanical relays, the PhotoMOS
relay combines LED and optoelectronic
device to transfer signals using light for
extremely high isolation.
5. Eliminates the need for a counter
electromotive force protection diode in
the drive circuits on the input side
6. Stable on resistance
7. Low-level off state leakage current
8. Eliminates the need for a power sup-
ply to drive the power MOSFET
A power supply used to drive the power
MOSFET is unnecessary because of the
built-in optoelectronic device. This results
in easy circuit design and small PC board
area.
9. Low thermal electromotive force
(Approx. 1 µV)
