The SPST-NO (1 Form A) output means it closes one isolated circuit when the input LED is forward-biased at the 1.14 VDC threshold — no mechanical contacts, no bounce, no arc. The SOP-4 package's thermal path to the board must handle that continuous dissipation without exceeding the junction limit — a consideration for high-duty-cycle or always-on applications. ## SOP-4 footprint and surface-mount integration The surface-mount terminations suit reflow assembly alongside other passives and ICs on the same board. ## AC/DC output — one relay for both polarities Unlike an electromechanical relay that switches DC with a polarity-dependent arc, the PhotoMOS output stage handles AC or DC loads through the same terminals — the MOSFET back-to-back pair blocks and conducts in both directions. This simplifies the BOM when the load side could be either polarity or an AC signal.","metaTitle":"Panasonic AQY212S PhotoMOS Relay, SPST-NO, 500 mA, 60 V","metaDescription":"Active-production Panasonic AQY212S PhotoMOS relay, SPST-NO, 500 mA load, 60 V AC/DC, 2.5 Ohm on-resistance.
