100V N-channel in a DPAK — what the ratings mean for the board
The STD6NF10T4: That 100 V Vdss puts it in the 80–100 V sweet spot for 48 V telecom bricks, 24 V industrial supplies, and 12 V automotive auxiliary loads with margin for transients.
Housed in the TO-252-3 (DPAK) package, the STD6NF10T4's exposed tab is the drain connection — the PCB land pattern must tie the tab to the drain node with enough copper area to keep the junction below 175 °C at full load.
