Ratings that decide the fit
The BUK7528-55A,127: On-resistance is specified at 28 mOhm max with 10 V gate drive at 25 A — this is the conduction loss figure for the switching loop; at full load the dissipation stays under 30 W, leaving headroom within the 99 W package limit at 25°C case.
Through-hole TO-220-3 (TO-220AB) — the standard three-lead power package with a metal tab for heatsink mounting. The 2.54 mm pitch on the leads matches common PSU and motor-drive PCB layouts; no custom footprint needed. Input capacitance is 1165 pF at 25 V Vds — a moderate figure that keeps gate-drive losses low at switching frequencies up to a few hundred kHz without requiring a special high-current driver.
Lifecycle and compliance
ROHS3 compliant — no restricted substances above the exemption thresholds, so it ships into EU, UK, and other regulated markets without a waiver. The Tube package is standard for through-hole devices; no special handling beyond normal ESD precautions.
