It switches with a 1.13 VDC input, and the 35 Ohm max on-state resistance means the voltage drop across the relay at 120 mA is about 4.2 V — fine for signal-level loads but not for power delivery. The 4-SOP package with Gull Wing leads is a standard surface-mount footprint for signal relays, so it fits into automated pick-and-place assembly without special handling. ## What the ratings mean for your BOM The 120 mA load current is the continuous DC or AC RMS limit — this part is sized for signal switching (telecom, instrumentation, sensor outputs), not for driving solenoids or motors. The 350 V load voltage ceiling covers 240 VAC mains-derived signals with margin, or 48 V telecom rails comfortably. On-state resistance of 35 Ohms is typical for a PhotoMOS in this voltage class — it limits the part to low-current signal paths where the voltage drop is acceptable.","metaTitle":"Panasonic AQY210KSZ PhotoMOS Relay, SPST-NO, 120 mA, 350 V","metaDescription":"Panasonic AQY210KSZ PhotoMOS relay, SPST-NO, 120 mA load, 350 V AC/DC, 4-SOP surface mount.
