The DPAK (TO-252) surface-mount package keeps the footprint compact for automated assembly in power stages, load switching, and DC-DC conversion blocks. ## Temperature range and junction limits Operating junction temperature spans -55°C to 175°C, which covers under-hood automotive, industrial motor drives in hot enclosures, and outdoor telecom power supplies. The 88W power dissipation at case temperature gives thermal headroom for continuous conduction — but the junction limit is the binding constraint for real load profiles, not the package tab. ## Gate drive and switching Gate threshold voltage is 4V maximum at 1mA drain current, but the on-resistance is specified at 10V drive — so a 10V gate rail is needed to hit the rated 30mOhm. The input capacitance is 1152 pF at 25V drain bias, which is moderate for a 38A device. That Ciss figure drives the gate charge and therefore the switching loss in a hard-switched converter; a gate driver with enough peak current to charge it in the target dead-time is the design-in check. ## Package and assembly Surface-mount reflow profile follows standard MSL for DPAK; the tab needs a good solder joint or thermal-via stitch to the PCB copper plane to keep junction temperature in check at high current.","metaTitle":"NXP BUK7230-55A,118 MOSFET, 55V 38A N-Channel DPAK","metaDescription":"AEC-Q101 qualified N-channel TrenchMOS, 55V Vds, 38A Id, 30mOhm Rds(on) at 10V.
