Obsolete — sourcing path for the AQY221FR2VY
The part is available through independent surplus and broker channels.
RF-rated solid-state relay — key parametrics
SPST-NO (1 Form A) output, rated for both AC and DC (RF) loads up to 250 mA continuous, with a load voltage range of 0 V to 40 V. On-state resistance is 1.25 Ohms max — this is the conduction loss floor at rated current; for a 250 mA load the voltage drop is roughly 0.31 V, which matters in low-voltage signal paths.
4-SSOP package — board-fit note
Supplied in a 4-SMD package (0.175" × 0.175", 4.45 mm body) with SMD (SMT) Tab termination — the supplier device package is designated 4-SSOP.
