7. PC board layout is simplified
8. Eliminates the need for a separate
power supply to drive the power MOSFET
9. Low thermal electromotive force
(Approx. 1 µV)
10. No restriction on mounting direction
11. No arc, no bounce, no noise
1. 4-circuit (4-Form A) of GU
PhotoMOS Relay in a compact and slim
13 pin SIL
2. Applicable for 4 Form A use, as well
as 4 independent 1 Form A
3. Controls low-level analog signals
PhotoMOS relays feature extremely low
closed-circuit offset voltage to enable
control of low-level analog signals without
distortion.
4. Low-level off state leakage current
(Typical 100 pA at 100 V load voltage)
5. Optical coupling for extremely high
isolation
6. Eliminates the need for a counter
electromotive protection diode in the
drive circuit on the input side
