Panasonic AQY4C PCB-Mount PhotoMOS® are solid-state, CC-type relays that are normally closed and come in an ultra-miniature TSON package (1.95mm x 1.80mm x 0.8mm). These relays use capacitive isolation technology and are approximately 88% smaller than the previous SOP-packaged devices, offering a 3.5mm2 mounting area. Low current consumption and a 0.2mA maximum input current contribute to energy savings and increase drivability. The Panasonic AQY4C PhotoMOS series features voltage driving type components with a 3V to 5V input voltage range. Performance is guaranteed at temperatures up to +105°C. Applications include measuring equipment, security equipment, and voltage operating equipment that requires low electricity consumption.
