It switches a resistive or inductive load on the high side using an N-channel MOSFET with a typical on-resistance of 250 mOhm. ## What the 250 mOhm Rds(on) and 400 mA rating mean for your BOM At 400 mA, the 250 mOhm typical Rds(on) produces a conduction loss of I²R = 40 mW — negligible for the SOIC-8 package's thermal budget, but the junction temperature derating matters: the device is specified over -40°C to 150°C junction, and Rds(on) roughly doubles at 150°C vs 25°C, so actual voltage drop at high temperature is about 200 mV at full load. The 400 mA continuous rating is the DC limit; the miniPROFET architecture handles inrush and short-circuit pulses via fixed current limiting (one of the integrated fault protections), so a lamp or capacitive load starting cold won't latch off as long as the pulse stays within the SOA. ## Fault protection set and temperature grade Protection covers current limiting (fixed threshold), over-temperature shutdown, and over-voltage clamping — no external sense resistor or TVS needed for most automotive load-dump scenarios up to 34 V. The input is non-inverting: logic high turns the switch on. ## Sourcing and lifecycle posture ROHS3 compliant. No official second-source or pin-compatible cross-reference is documented in the Infineon portfolio; the BSP742RIXUMA1 is the standard SOIC-8 variant for this miniPROFET current rating. Available in Tape & Reel (standard production reel) or Cut Tape for prototype quantities.","metaTitle":"Infineon BSP742RIXUMA1 miniPROFET, 400 mA, 250 mOhm, SOIC-8","metaDescription":"Infineon BSP742RIXUMA1 miniPROFET high-side switch, 400 mA, 250 mOhm Rds(on), 5-34 V load, -40 to 150°C, PG-DSO-8-6.
