Product details

The NXP BUK7516-55A,127 is a 55 V, 65.7 A N-channel TrenchMOS power MOSFET in a through-hole TO-220AB package.

Gate drive voltage and Rds(on) — the 10 V gate-drive requirement

The 16 mOhm Rds(on) is specified at Vgs = 10 V, which is the drive voltage for minimum on-resistance. Designs using 3.3 V MCU outputs need a gate driver or level shifter to reach 10 V for full rated performance.

Derate the 65.7 A continuous current rating above 25°C case temperature per the datasheet's thermal curve.

Input capacitance and switching speed

The input capacitance (Ciss) is 2245 pF typical at Vds = 25 V. This is moderate for a 65 A rated MOSFET — the gate driver must supply enough peak current to charge and discharge this capacitance for fast switching. A 1 A gate driver will handle switching frequencies up to several hundred kHz; for higher frequencies, budget gate drive current accordingly.

It is ROHS3 compliant.
