The -55 to 175 °C junction range covers under-hood automotive and industrial environments where ambient temperatures push 125 °C. ## Switching and drive considerations The input capacitance is 4230 pF typical at 25 V drain-source. That is moderate for a 75 A device — the gate driver needs to source and sink enough peak current to hit the target switching frequency without excessive crossover loss. The ±10 V gate-source maximum limits the drive voltage; a 10 V gate drive is the standard choice for minimum Rds(on). The 2 V maximum gate threshold at 1 mA drain current means the device is fully enhanced with logic-level gate drives above 5 V, but the 10 mOhm Rds(on) spec is guaranteed at 10 V only. For lower gate voltages the on-resistance rises — check the typical curve in the datasheet if the gate drive is 5 V.","metaTitle":"BUK9511-55A,127 N-Channel MOSFET, 55 V, 75 A, TO-220AB","metaDescription":"NXP BUK9511-55A,127 N-channel TrenchMOS MOSFET, 55 V drain-source, 75 A continuous drain, 10 mOhm Rds(on) at 25 A.
