Product details

What the 1 A / 30 V rating means for your BOM

The AQY211EHA is a PhotoMOS™ AQY series solid-state relay from Panasonic Electric Works, switching a 1 A load at up to 30 V AC or DC through a single-pole single-throw normally-open (SPST-NO, 1 Form A) output. The 500 mOhm maximum on-state resistance means the relay drops about 0.5 V at full load — low enough to keep self-heating manageable in a signal path or low-power actuator circuit, but worth checking against your load's minimum operating voltage if you are switching near the 30 V rail.

Frequently asked questions

What is the on-state resistance of the AQY211EHA and why does it matter?

The maximum on-state resistance is 500 mOhms. At 1 A load current this means roughly 0.5 V drop across the relay — low enough for most signal and low-power switching, but if your load needs the full 30 V rail at 1 A, the 0.5 V drop reduces the delivered voltage to about 29.5 V.
