The 4300 pF input capacitance at 75V drain bias is moderate. The specified drive voltage range of 8V to 10V for rated Rds(on) means a 5V microcontroller output cannot fully enhance this device — a gate driver or level-shift stage is required. ## Thermal limits and heatsink planning Maximum junction temperature is 175°C, with power dissipation rated at 40.5W at case temperature. At 37A continuous current, conduction loss alone (I² × Rds(on)) at 25°C junction is about 14.4W — within the 40.5W ceiling, but junction temperature will rise above 25°C, increasing Rds(on) by roughly 50% at 125°C junction. A heatsink is needed for sustained 37A operation; the TO-220 Full Pack's thermal resistance junction-to-case is higher than a standard TO-220 because the plastic overmold adds a thermal barrier. The -55°C to 175°C operating range covers automotive under-hood and industrial oven environments. ## Lifecycle and compliance ROHS3 compliant. The base product number is IPA105; the suffix identifies the TO-220 Full Pack variant.","metaTitle":"IPA105N15N3GXKSA1 OptiMOS N-Ch 150V 37A TO-220FP","metaDescription":"Infineon IPA105N15N3GXKSA1 N-channel MOSFET, 150V Vdss, 37A Id, 10.5mOhm Rds(on) at 10V.
