Product details

PhotoMOS AQY211EH — 1 A SPST-NO solid-state relay in a 4-DIP through-hole package

The AQY211EH is a Panasonic PhotoMOS relay from the AQY series, switching AC or DC loads up to 1 A at 30 V through a single-pole normally-open (SPST-NO) output. Housed in a standard 4-DIP package with PC pin termination, it drops into a through-hole socket on the board — no hot-air station needed for a field swap.

On-resistance and load handling — 500 mOhm max, 1 A continuous

Maximum on-state resistance is 500 mOhms, so at 1 A the voltage drop across the relay is under 0.5 V — negligible in a low-voltage signal path. The output handles both AC and DC loads up to 30 V, making it a direct replacement for a mechanical reed relay in applications where silent switching and longer life matter.

Active lifecycle — no last-time-buy pressure

Panasonic lists the AQY211EH as Active — no EOL notice, no successor to track, and no urgency to stockpile for an obsolescence-driven redesign.

Frequently asked questions

What is the AQY211EH's on-resistance and what does it mean for my circuit?

Maximum on-resistance is 500 mOhms. At 1 A load current the voltage drop is under 0.5 V, so it adds negligible loss in a low-voltage signal path or small power-switching application.

Can I swap the AQY211EH in the field without a rework station?

Yes — the 4-DIP through-hole package with PC pin termination fits a standard DIP socket. No hot-air or soldering iron needed for the swap if the board uses a socket.
