Product details

PhotoMOS AQY210S1Y — 120 mA solid-state relay for signal switching

The Panasonic AQY210S1Y is a PhotoMOS™ AQY series solid-state relay in a 4-SOP surface-mount package with gull-wing leads. It switches AC or DC loads up to 120 mA continuous at voltages from 0 V to 350 V, making it a fit for signal-level isolation and switching in test equipment, telecom, and industrial control boards.

On-state resistance and input drive

Maximum on-state resistance is 25 Ohms — this sets the voltage drop across the output at full load (3 V drop at 120 mA), which matters for low-voltage signal paths where the relay's own drop must stay below the logic threshold.

Package and board integration

Housed in a 4-SOP (0.173-inch body width, 4.40 mm body height) with gull-wing leads, the AQY210S1Y sits in a standard SOIC-4 footprint. The surface-mount package suits automated pick-and-place assembly and reflow soldering. Supplied on Tape & Reel (TR), it is ready for volume production lines.

Frequently asked questions

What is the on-state resistance of the AQY210S1Y and why does it matter?

Maximum on-state resistance is 25 Ohms. At the rated 120 mA load current, this produces a 3 V drop across the output — a consideration when switching low-voltage analog or digital signals where the relay's drop must stay below the receiver's threshold.

What package and termination does the AQY210S1Y use?

It comes in a 4-SOP surface-mount package (0.173-inch body width, 4.40 mm height) with gull-wing leads. The footprint matches a standard SOIC-4 layout.
