25 V N-channel FET with 2.1 mOhm Rds(on) — conduction loss floor
That Rds(on) figure, specified at the full rated current, sets the conduction loss for a synchronous rectifier or a low-side switch in a 12 V or 24 V rail — at 29 A the I²R loss is under 1.8 W, which the 2.8 W package power rating can handle with adequate board copper.
Gate charge and switching speed — sizing the driver
Total gate charge is 44 nC at 4.5 V Vgs, meaning a driver sourcing 1 A can turn the FET on in about 44 ns. The ±20 V maximum gate rating gives headroom for gate-drive overshoot in a hard-switching topology — a 12 V gate drive rail is well inside the safe window. The 0.0039 µF input capacitance (Ciss) is consistent with a die sized for 166 A pulsed drain current.
Temperature range and operating environment
The 2.4 V maximum gate threshold at 100 µA ensures the device turns on cleanly with a 3.3 V logic-level gate drive, though the 2.1 mOhm Rds(on) is specified at 10 V Vgs for lowest resistance.
Sourcing and lifecycle posture
Listed with an active lifecycle status. The part is a current-production Infineon DirectFET MOSFET, sourced through independent distribution.
