Product details

Active PhotoMOS relay for RF signal switching

The Panasonic AQY221N2VW is an SPST-NO (1 Form A) solid-state relay from the PhotoMOS AQY series, designed for switching AC or DC signals including RF paths. It handles a load current of 120 mA across a 0 V to 40 V range, with a maximum on-state resistance of 12.5 Ohms.

Surface-mount footprint and storage

Housed in a 4-SMD package (0.175", 4.45 mm body) with the supplier device package designation 4-SSOP, this relay mounts on standard surface-mount pads. The SMD (SMT) Tab termination style suits reflow soldering profiles typical for small-outline packages.

Frequently asked questions

What is the on-state resistance of AQY221N2VW?

The maximum on-state resistance is 12.5 Ohms. This value determines the voltage drop across the relay at the rated 120 mA load current — at full load the drop is about 1.5 V, which matters for low-voltage signal paths.
