It integrates an N-channel MOSFET with a 30 mOhm typical Rds(on) and a full suite of fault protections — current limiting, open-load detection, over-temperature shutdown, and over-voltage clamp — so the BOM does not need external sense resistors or comparators. ## Load voltage and current — what the 4.5 V to 32 V range covers The 36 A maximum output rating is a pulsed/start-up ceiling; continuous current is limited by the package thermal impedance and the 150°C junction temperature limit. Because the input type is non-inverting and the interface is a simple On/Off logic pin, the switch turns on when the gate drive is high — no PWM controller or level shifter needed. The slew-rate controlled turn-on reduces EMI and inrush current into capacitive loads. ## Thermal and package — the TO-263 tab is the heatsink Auto-restart after a fault clears is enabled by default — the switch re-closes once the over-temperature or over-current condition is removed, which suits intermittent loads like motors or solenoids without external reset circuitry.","metaTitle":"Infineon BTS430K2E3122A PROFET High-Side Switch, 30 mOhm","metaDescription":"Infineon BTS430K2E3122A PROFET high-side switch, 30 mOhm Rds(on), 36 A max, -40°C to 150°C junction.
