This matters for precision analog switching where a 1.5 V drop in the signal path must be budgeted. The output type is rated for AC, DC, and RF signals — the PhotoMOS construction with back-to-back MOSFETs gives low off-state leakage and fast switching, making it suitable for test equipment, sensor signal routing, and RF front-end switching where a mechanical relay's contact bounce would introduce noise. Housed in a 4-SMD package measuring 0.175\" (4.45 mm) body length — the 4-SSOP footprint with SMD (SMT) Tab termination suits standard pick-and-place and reflow assembly. No through-hole step needed.","metaTitle":"AQY221N2V1W PhotoMOS™ SPST-NO, 120 mA, 40 V, 4-SSOP","metaDescription":"Panasonic AQY221N2V1W PhotoMOS™ RF relay, SPST-NO, 120 mA load, 40 V, 12.5 Ohm on-resistance, 4-SSOP SMD.
