Product details

120 mA, 350 V PhotoMOS relay in a 4-SOP package

The Panasonic AQY210SX is a PhotoMOS™ AQY series solid-state relay with an SPST-NO (1 Form A) output, rated for 120 mA continuous load current and a load voltage range of 0 V to 350 V AC or DC.

Supplied in Tape & Reel (TR) or Cut Tape (CT) options, the part is compatible with standard pick-and-place assembly for surface-mount production.

Frequently asked questions

What is the on-state resistance of the AQY210SX and why does it matter?

The maximum on-state resistance is 25 Ohms. At the rated 120 mA load current, this produces a 3 V drop across the relay — the load must tolerate that voltage loss at the bottom of its operating range.

What package does the AQY210SX use and is it compatible with standard SOP-4 footprints?

It uses a 4-SOP package (0.173", 4.40 mm body width) with gull-wing leads, matching the standard SOP-4 footprint used by many optocouplers and solid-state relays.

Can the AQY210SX switch both AC and DC loads?

Yes, the output type is rated for both AC and DC, with a load voltage range of 0 V to 350 V.
