PhotoMOS relay for 600 V signal isolation
The AQY216EHAZ is a 50 mA, 600 V AC/DC solid-state relay in the PhotoMOS AQY series, switching both polarities through a single SPST-NO output. On-state resistance is 120 Ohms max — at 50 mA load the voltage drop across the output is about 6 V, so the relay is best suited for signal-level switching where the resistive loss is tolerable, not for power delivery.
Housed in a 4-SMD package with a 0.300-inch (7.62 mm) body width and gull-wing leads — the lead pitch and footprint match standard SOIC-4 layouts, so no special pad geometry is needed.
