The 500 mOhm max on-state resistance sets the conduction loss — at 1.25 A the dissipation is roughly 0.78 W, which the 4-SOP package must sink through the board copper. ## Surface-mount package and board integration Housed in a 4-SOP (0.173\", 4.40 mm body) with gull-wing leads, the AQY212G2SX sits in a standard surface-mount footprint. The SPST-NO (1 Form A) output is a single normally-open contact, so the relay closes when the input LED is forward-biased. The 4-SOP package is common across the AQY family, making it a drop-in fit for existing layouts that already use this footprint.","metaTitle":"Panasonic AQY212G2SX PhotoMOS, 1.25 A, 60 V, SPST-NO","metaDescription":"Active Panasonic AQY212G2SX PhotoMOS relay, 1.25 A load current, 60 V AC/DC, 500 mOhm on-resistance, 4-SOP surface mount.
