600 V N-channel in DPAK — the offline power switch
The STD7N60M2: It is built for hard-switching topologies in off-line power supplies — flyback converters, PFC stages, and auxiliary bias rails where the primary-side switch sees the full rectified DC bus plus leakage spike.

DPAK footprint and thermal reality
The TO-252-3 (DPAK) package with exposed tab requires a minimum 600 mm² copper area on the drain pad for the 60 W dissipation rating to hold.
