The input capacitance of 2340 pF at 25 V drain-source is moderate — the driver sees a capacitive load that rises with the Miller plateau, but the 30 nC Qg keeps the switching loss manageable up to several hundred kHz. ## 175 °C junction — headroom for harsh environments This matters for designs where the MOSFET sits near a hot exhaust manifold, in a downhole tool, or inside a sealed enclosure with limited airflow — the 175 °C Tj(max) allows the part to survive transient overloads that would push a 150 °C-rated device past its absolute maximum. ## PG-TO263-3-2 — reflow assembly and thermal interface The package is a standard TO-263-3 (D²Pak) with the supplier code PG-TO263-3-2. The three-lead footprint matches the industry-standard D²Pak land pattern, so no custom footprint is needed.","metaTitle":"IPB45N04S4L-08 N-Channel MOSFET, 40 V, 45 A, 7.9 mOhm","metaDescription":"Infineon IPB45N04S4L-08 OptiMOS™T2 N-channel MOSFET, 40 V drain-source, 45 A continuous, 7.9 mOhm Rds(on) max at 10 V.
