Solid-state signal relay for isolated AC load switching
The Panasonic AQH0213A is a solid-state signal relay from the AQ-H series, designed for isolated switching of low-power AC loads in signal-level circuits. Its SPST-NO (1 Form A) circuit switches up to 300 mA across a 0 V to 600 V load voltage range, covering common signal and control AC rails without mechanical contact wear.
Zero-cross switching and input drive
The AC zero-cross output type fires the relay at the voltage waveform's zero point, which limits inrush current into capacitive or lamp loads and reduces conducted EMI at turn-on.
Surface-mount package and board integration
Housed in an 8-SMD package with a 0.300-inch (7.62 mm) body width and 7 leads, the gull-wing termination style suits standard reflow soldering profiles and provides visual solder-joint inspection access. The supplier device package is designated 8-SMD; the base product number AQH0213 anchors the variant, with the trailing 'A' indicating the tube packaging option.
