It switches a grounded load up to 9.5 A continuous from a supply rail of 28 V max, with a typical on-resistance of 40 mOhm. The low Rds(on) keeps conduction loss under 3.6 W at full rated current — manageable with the TO-220 tab soldered to a copper plane or clamped to a heatsink. This is a self-contained switch: no external Vcc supply is required — the gate drive is powered from the load voltage. The input is non-inverting, so a logic high on the gate pin turns the output on. Built-in fault protection includes current limiting (fixed threshold) and over-temperature shutdown, eliminating the need for external sense resistors or thermal monitoring. ## Obsolete — last-time-buy sourcing route For new designs, Infineon's current low-side switch portfolio (e.g., PROFET or BTS-series smart switches) should be evaluated for pin-compatible fit. ## Thermal and protection features for industrial loads The over-temperature protection trips before the silicon exceeds the 150°C limit, making it resilient to stalled fan or shorted solenoid loads. The current-limiting threshold is fixed — no external resistor programming — so the trip point is non-negotiable; confirm the load inrush does not exceed the limit during start-up.","metaTitle":"Infineon IPS1031PBF Low-Side Switch, 9.5A, 40 mOhm, Obsolete","metaDescription":"Infineon IPS1031PBF low-side N-channel power switch, 28V load, 9.5A output, 40 mOhm Rds(on), TO-220AB.
