Housed in the PG-SOT-23-3 (SC-59, SOT-23-3) surface-mount package, it fits the standard small-signal footprint you see on control boards, I/O modules, and sensor interfaces. The 500 mW power dissipation limit at ambient tells you this is a signal-level switch, not a power converter — think gate drive, load switching under 100 mA, or level translation. ## Parametric fit for low-power rails Maximum on-resistance is 6 Ohms at Vgs = 10 V with Id = 190 mA. For a 50 mA load that translates to roughly 15 mW conduction loss — negligible in most designs, but the Rds(on) doubles roughly every 50°C junction rise, so budget the thermal margin if the ambient runs above 85°C. ## Active and compliant — no obsolescence worry The wide temp range means it can sit next to a hot regulator or in an outdoor enclosure without derating concerns at the signal level.","metaTitle":"Infineon BSS123IXTSA1 N-Channel MOSFET, 100V, 190mA, SOT-23","metaDescription":"Infineon BSS123IXTSA1 N-Channel OptiMOS MOSFET, 100V Vdss, 190mA Id, 6 Ohm Rds(on), SOT-23-3.
