55 V, 160 A N-Channel — the load-budget anchor
The NP160N055TUK-E1-AY: That 160 A figure is the headline — it tells you this FET is built for a high-current rail, not a signal-level switching job.
189 nC gate charge — what it asks of the driver
Gate charge totals 189 nC at a 10 V drive. Input capacitance is 11250 pF at 25 V drain-source.
175 °C junction — thermal margin for tight enclosures
The maximum junction temperature is 175 °C, which is the high end for a power MOSFET. That gives thermal headroom in applications where the ambient runs hot — under-hood automotive electronics, motor-drive cabinets, or power supplies with restricted airflow. The power dissipation ceiling is 250 W at the case, but the 1.8 W at ambient rating reminds you that without a heatsink or board copper, the part derates sharply.
The package is a TO-263-7 (D²Pak) with 6 leads plus a tab. The 6-lead count means the gate and source are brought out on separate pins, which helps keep the gate-drive loop tight. Surface-mount assembly is standard reflow; no through-hole work on site.
Active lifecycle — no end-of-life clock ticking
The NP160N055TUK--AY carries an active product status.
