Panasonic AQZ10xD and AQZ20xD Voltage Sensitive High Capacity PhotoMOS® are relays that come in a slim SIL 4-pin package (21.0mm x 3.5mm x 12.5mm), enabling high-density mounting. The modules feature a space-saving design, a low on-resistance (0.033Ω typical), and high sensitivity. The relays are available in AC/DC dual type and DC-only type. The AC/DC dual type is capable of bidirectional control, and unlike conventional SSRs, does not have to be used differently depending on the load. The DC-only type is well suited for the control of DC solenoids and DC motors. The high-capacity relays can switch a wide range of currents and voltages while controlling various types of loads, from small to 2.7A maximum for the AC/DC dual type and 3.6A maximum for the DC-only type. The conventional power PhotoMOS series is connected externally to an input limiting resistor to obtain the appropriate LED current. With the addition of an internal constant current element, the input limiting resistor is rendered unnecessary, making it possible for the Panasonic PhotoMOS to be voltage-driven.
