Maximum on-state resistance is 180 mΩ — at 2 A that is 0.72 W of dissipation in the conduction path, so the relay body needs adequate board copper or a thermal via array to stay within its operating temperature window. ## Input drive and what 1.16 VDC means for the control circuit The LED trigger voltage is listed at 1.16 VDC — this is the forward voltage the PhotoMOS LED must see to actuate. The logic-level compatibility of the driving rail (3.3 V, 5 V, or 24 V control) determines whether a current-limiting resistor is required; the datasheet drive circuit section specifies the LED current needed to hit the rated on-state resistance. Because PhotoMOS relays have no coil, there is no inductive kickback on release — the input side is purely an LED with a defined forward voltage range, making the drive simpler than a flyback-clamped relay coil. ## SMT footprint and the gull-wing termination Tape-and-reel packaging makes it suitable for SMT pick-and-place in volume production; the gull-wing coplanarity must be verified on incoming inspection before reflow if the reels have been in extended storage. ## Active status and the AQY272 base product number Listed as Active — the AQY272 base product number groups the family variants; the AQY272AX suffix carries the tape-and-reel orientation and specific LED drive characteristics consistent with the AQY272 series footprint.","metaTitle":"Panasonic AQY272AX PhotoMOS Relay, 2 A, 60 V, 180 mΩ","metaDescription":"Panasonic Electric Works PhotoMOS AQY272AX, SPST-NO solid-state relay rated 2 A max load current, 0–60 V load voltage, 180 mΩ on-resistance.
