Product details

RF-rated solid-state relay in a 2.95 mm SON package

The Panasonic AQY221N2MW is a PhotoMOS AQY series signal relay with an SPST-NO (1 Form A) circuit, rated for 120 mA load current across 0 to 40 V AC or DC. Its 12.5 ohm max on-state resistance keeps insertion loss low enough for RF and analog signal paths — think test equipment front-ends, multiplexed sensor channels, or ATE pin electronics where a mechanical relay's bounce and wear are unacceptable.

Package and rework reality — 4-SON with SMD tabs

Pin 1 is marked by a chamfer on the package corner; verify orientation before reflow.

Active production — no last-time-buy pressure

Panasonic lists the AQY221N2MW as Active. This is a current-production part, sourced through authorized and independent distribution channels.

Frequently asked questions

What is the on-state resistance of the AQY221N2MW?

Maximum on-state resistance is 12.5 ohms. This is the resistance between the output terminals when the relay is turned on — it determines the voltage drop and self-heating at the rated 120 mA load.

What package does the AQY221N2MW use?

It comes in a 4-SON (4-lead small-outline no-lead) package, 2.95 mm body width, with SMD tabs for soldering. The supplier device package is also designated 4-SON.
