POWER PhotoMOS RELAYS (Voltage Sensitive Type) PhotoMOS RELAYS 4. Both AC/DC dual types and DC-only types are available The AC/DC dual type is capable of bi-directional control, and unlike conventional SSRs, does not have to be used differently depending on the load. The DC-only type is well suited for control of DC solenoids and DC motors. 5. High sensitivity, low ON resistance A maximum 3.6 A load can be controlled with the minimum input voltage of 4 V DC. The ON resistance is also low at 0.09 Ω (AQZ102D). 6. Small scale, slim type, 4-pin SIL Length 21.0 mm×width 3.5 mm×height 12.5 mm. High precision mounting is possible because of the small 73.5mm2 area of the 4-pin SIL. 21±0.2 .827±.008 3.5±0.2 .138±.008 12.5±0.2 .492±.008 FEATURES 1.
