Product details

Built in the TO-220AB through-hole package, it mates to a standard TO-220 footprint on a heatsink or PCB. The 95 nC gate charge at 5 V tells the switching driver what to budget for turn-on and turn-off transitions.

AEC-Q101: the qualification gate for underhood deployment

This part carries a listed AEC-Q101 qualification and an active product status. For a Tier-1 submitting PPAP to an OEM, the AEC-Q101 listing is the documentation hook. The ROHS3 compliance removes the material-restriction question from the BOM review.

120 A continuous — what the rating means for the load budget

The 120 A Id at 25°C is a case-temperature-limited rating. At 175°C junction the continuous current derates significantly; the 293 W dissipation cap at 25°C ambient sets the practical thermal budget. A 60 V Vdss gives 20% headroom above a nominal 48 V bus or 13% above a 52 V boost rail. Combined with 95 nC Qg, it tells you the driver must source several amperes peak to hit switching edges under 100 ns.

Frequently asked questions

Is BUK953R5-60E,127 AEC-Q101 qualified for automotive use?

Yes, the BUK953R5-60E,127 is listed as AEC-Q101 qualified in the Automotive TrenchMOS series. This is the documentation basis for PPAP submission to an OEM auditor. The -55°C to 175°C junction range supports underhood temperature profiles.

What is the Rds(on) of BUK953R5-60E,127 at 10V gate drive?

The maximum on-resistance is 3.4 mOhm at 25 A drain current with 10 V applied between gate and source. This is the figure to use for conduction-loss calculations at full load.
