Product details

The STD8N65M5: Surface-mount DPAK (TO-252) package. The 650 V rating gives comfortable headroom for a universal AC-input power supply (rectified line ~375 VDC) or a 400 VDC PFC bus. The 7 A continuous current is derated by case temperature — at 100 °C case the usable current drops, so check the thermal derating curve in the datasheet.

600 mOhm Rds(on) and 15 nC gate charge — the switching loss vs conduction loss trade-off

Maximum on-resistance is 600 mOhm at 3.5 A drain current with 10 V gate drive. 15 nC total gate charge at 10 V. Input capacitance is 690 pF at 100 V Vds — a light capacitive load that further eases the driver's job.

Active lifecycle and compliance — no near-term obsolescence concern

It is ROHS3 compliant. The base product number is STD8N65, covering the DPAK variant family.
