It comes in a 4-SOP package (0.173\", 4.40 mm body) with gull-wing leads, surface-mount termination — the same footprint as a standard SOP-4 optocoupler, so it drops into existing PCB layouts without a board spin. ## On-resistance and load current — the trade-off for a 350 V blocking voltage The 35 Ohm on-state resistance (max) is the price of the 350 V drain-to-drain blocking voltage in a small SOP package. At 120 mA load, the voltage drop across the relay is 4.2 V — that is 0.5 W dissipation, well within the SOP-4 thermal budget for a signal-level load. ## Active production — no last-time-buy pressure The base product number AQY21 covers the family; the KSX suffix denotes the 4-SOP gull-wing package on tape-and-reel.","metaTitle":"Panasonic AQY210KSX PhotoMOS Relay, 120 mA, 350 V, 4-SOP","metaDescription":"Panasonic AQY210KSX PhotoMOS AQY series signal relay, SPST-NO, 120 mA load, 350 V, 35 Ohm on-resistance, 4-SOP gull wing.
