600 mA SPST-NO zero-cross relay for AC load switching
The Panasonic AQH1213AZ is an AQ-H series solid-state signal relay with a single-pole single-throw normally-open (SPST-NO) output rated for 600 mA continuous load current across a 0 V to 600 V AC range. The integrated zero-cross detection circuit turns the output on only when the AC waveform crosses zero, reducing inrush current and EMI when switching resistive or lightly inductive loads like solenoids, lamps, or small transformers.
Housed in an 8-SMD package (7.62 mm body width, 7 leads) with gull-wing terminals, the AQH1213AZ suits surface-mount assembly on standard FR-4 boards. The 0.300-inch (7.62 mm) lead spacing matches legacy DIP-8 footprints, so a single PCB layout can accommodate both through-hole and SMD variants of the AQ-H family. Supplied in Tape & Reel (TR) or Cut Tape (CT) packaging — the reel quantity suits medium-to-high volume pick-and-place; the cut tape option works for prototype runs or low-volume builds without committing to a full reel.
Active production — sourcing posture
The base product number AQH1213 covers multiple package and tape options — the AZ suffix denotes the specific reel configuration. When ordering, confirm the suffix matches the assembly line's feeder setup.
