Product details

650 V N-channel in DPAK — MDmesh II for offline power

The STD10NM65N: The 25 nC typical gate charge at 10 V keeps switching losses manageable in a hard-switched converter. The part comes in a DPAK (TO-252) surface-mount package.

Obsolete — plan for a last-time buy or alternate

The STD10NM65N is listed as Obsolete.

The 90 W maximum power dissipation is rated at the case (Tc), not ambient — that figure assumes the case is held at 25 °C, which in practice means a substantial heatsink or a good thermal connection to the PCB copper plane.
