The SPST-NO (1 Form A) output gives you a normally-open contact that closes when the input is energised — no mechanical coil, no contact bounce, and no arc across the switching element. ## On-resistance and thermal budget The 2.5 Ohm max on-state resistance sets the conduction loss at 550 mA to roughly 0.76 W — well within the dissipation capability of the 4-SMD package when the copper traces on the PCB act as a heatsink. If your load current is lower, say 100 mA, the voltage drop across the relay is only 250 mV, which keeps the junction temperature rise negligible. ## Package and board integration The AQY212EHAZ comes in a 4-SMD package (0.300\", 7.62 mm body width) with gull-wing leads. The 7.62 mm body width matches the common DIP-4 footprint, so it sits on the same PCB land pattern as a through-hole PhotoMOS relay — the gull-wing leads give you a lower profile and reflow-solder compatibility. No special bake-out required for MSL 1 parts, but verify the reel date code if it has been stored beyond the floor-life window.","metaTitle":"Panasonic AQY212EHAZ PhotoMOS Relay, SPST-NO, 550 mA, 60 V","metaDescription":"Panasonic AQY212EHAZ PhotoMOS AQY series solid-state relay.
