The SPST-NO (1 Form A) contact arrangement means the output path is open when de-energised and closes when the LED is driven. The output type is listed as AC, DC (RF), which means the output MOSFET handles both polarities — a key distinction from a zero-crossing TRIAC output. This matters for analog signal routing or for DC loads that reverse polarity, where a TRIAC-based SSR would not commutate correctly. ## Load ceiling and on-resistance trade-off Load current is rated at 120 mA maximum — this is a signal-level ceiling, not a power-switching rating. The on-state resistance is specified as a maximum of 14 Ω, which at 120 mA produces roughly 1.7 V across the output in the worst case. For a 100 mA signal path this is a meaningful insertion loss; for a 1 mA sense line it is negligible. The load voltage range spans 0–100 V, so the part is unsuitable for 120 VAC or 240 VAC line switching but well-suited for low-voltage analog or digital signal buses. ## 4-SSOP SMD tab — what it demands of the board The 4-SSOP (4-SMD, 4.45 mm body width) package is a surface-mount tab-lead style. The tab termination is not a thermal pad in the power-semiconductor sense — it is the output common node — so the board layout must respect the isolation spacing implied by the load voltage rating. The part ships on tape and reel, which suits pick-and-place assembly in volume production. ## Where the AQY series fits in signal switching PhotoMOS relays of this rating are specified in test-and-measurement equipment, industrial process control, medical instrumentation, and in any application that requires galvanically isolated signal switching without the contact wear or bounce of a mechanical relay. The 14 Ω on-resistance is higher than a mechanical relay's sub-100 mΩ contact resistance, so the design trade-off is isolation versus insertion loss — the SSR wins where lifetime cycles exceed what a mechanical relay would survive, or where contact bounce cannot be tolerated in a high-speed data or timing path. For a second-source search within the same series, the base product number AQY225 is the starting point for a parametric cross-check across the family footprint and rating spread.","metaTitle":"Panasonic AQY225R3VY PhotoMOS Relay, 120mA, 100V","metaDescription":"Panasonic Electric Works AQY225R3VY, PhotoMOS AQY solid-state relay, SPST-NO, 120 mA load, 0–100 V, 14Ω max on-resistance, 4-SSOP SMD, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Signal Relays"],"specifications":{"Mfr":"Panasonic Electric Works","Series":"PhotoMOS™ AQY","Circuit":"SPST-NO (1 Form A)","Package":"Tape & Reel (TR) Cut Tape (CT)","Output Type":"AC, DC (RF)","Load Current":"120 mA","Mounting Type":"Surface Mount","Package / Case":"4-SMD (0.175\\\", 4.45mm)","Product Status":"Active","Voltage - Load":"0 V ~ 100 V","Voltage - Input":"1.14VDC","lifecycle_stage":"unknown","Termination Style":"SMD (SMT) Tab","Base Product Number":"AQY225","Supplier Device Package":"4-SSOP","On-State Resistance (Max)":"14 Ohms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3329","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fc0ab33ee4e3dc53e9b44062dc06f761.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What load voltage and current can the AQY225R3VY handle?","answer":"The load voltage range is 0–100 V and the maximum load current is 120 mA.
