The SPST-NO (1 Form A) output handles 0 V to 40 V across the load terminals, with a maximum on-state resistance of 12.5 Ohms — that resistance sets the self-heating at full current, so the 120 mA rating is the practical ceiling in a 4-SOP package without airflow. ## RF-rated output and package constraints The output is explicitly rated for AC, DC, and RF signals — the PhotoMOS construction gives faster switching and longer life than an electromechanical relay in RF path switching or low-level signal multiplexing.","metaTitle":"Panasonic AQY221N2SX PhotoMOS Relay, SPST-NO, 120 mA, 40 V","metaDescription":"Panasonic AQY221N2SX PhotoMOS relay, SPST-NO, 120 mA load, 40 V, 4-SOP surface mount.

At 120 mA load current, that resistance dissipates about 180 mW — well within the 4-SOP package's thermal budget, but it does mean the relay self-heats proportionally to the load current squared, so the 120 mA rating is the practical limit in still air."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panasonic-electric-works/AQY221N2SX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panasonic-electric-works/AQY221N2SX when reusing this data.
