The STP45N60DM2AG: Maximum on-resistance is 93 mOhm at 17 A drain current with 10 V gate drive — the 10 V drive rail is mandatory to achieve the rated Rds(on); driving from a 5 V logic rail leaves the FET in the linear region. At 34 A full load the conduction loss hits 107 W (I²R) before derating for junction temperature rise, so the 250 W power-dissipation ceiling at the case is the practical limit only with an adequate heatsink. Total gate charge is 56 nC at 10 V.
AEC-Q101 grade: what the OEM auditor expects to see
The STP45N60DM2AG carries AEC-Q101 qualification — not just 'automotive-capable' but formally qualified with the PPAP documentation an OEM auditor will request. Capable is not qualified; this part is.
Sourcing — production availability and channel posture
No stock-holding claim; the part is procured per the BOM quantity and lead time.
