600 mA AC load switching with 600 V blocking
The AQH1223AZ is a solid-state relay from Panasonic's AQ-H series, switching AC loads up to 600 mA across a 0 to 600 V range. The SPST-NO (1 Form A) contact arrangement is a simple single-pole normally-open switch — one output turns one load on or off. No latching, no polarity concerns on the AC side, just a clean isolated closure when the input LED is forward-biased above the threshold.
Housed in an 8-SMD package with a 7.62 mm body width and gull-wing leads, the AQH1223AZ suits standard surface-mount assembly flows. The 7-lead variant of the 8-pin DIP-style footprint means one pin is omitted — check the landing pattern against the datasheet before committing the PCB layout. The gull-wing leads provide good visual solder-joint inspection access, helpful for production quality checks.
