Its output type is specified for both AC and DC, with an RF-capable designation — the 12.5 Ohm max on-state resistance and low input drive voltage of 1.14 VDC make it suited for switching small signals in test equipment, ATE pin electronics, and RF front-end bypass paths where a mechanical relay's contact bounce or lifetime limits are unacceptable. ## Package and footprint fit Housed in a 4-SSOP package (4-SMD, 0.175\" body width), the AQY221N2VY occupies roughly 4.45 mm of board edge per side — a footprint that matches standard 4-pin SOP photocoupler and solid-state relay layouts. The SMD (SMT) Tab termination style means the device is reflow-solderable; the tape-and-reel option (TR) supports automated pick-and-place for volume builds.","metaTitle":"Panasonic AQY221N2VY PhotoMOS Relay, SPST-NO, 120 mA, 40 V","metaDescription":"Active Panasonic AQY221N2VY PhotoMOS relay, SPST-NO, 120 mA load, 40 V, 12.5 Ohm on-resistance. 4-SSOP SMD.
