Product details

What this 100 V, 40 A N-channel MOSFET is for

The TO-220 through-hole package allows mounting to a heatsink for thermal management in industrial and automotive power stages.

The 100 V Vdss gives headroom for 48 V bus rails, 24 V industrial supplies, and 12 V automotive systems — you can run it with derating margin in a 48 V nominal system. The 40 A continuous rating at 25°C case temperature is the package-limited current; at elevated case temperatures you derate per the thermal curve.

Obsolete — sourcing reality for STP35NF10

This means the factory no longer manufactures it, and no last-time-buy window is open. For new designs, a current-production alternative should be selected.

Frequently asked questions

What is the Vgs threshold of STP35NF10?

The maximum gate threshold voltage is 4 V at 250 µA drain current.
