The TO-220FP fully encapsulated case eliminates the need for an insulating pad when bolted to a grounded heatsink — a practical advantage in metal-enclosure designs where isolation creepage matters.
Input capacitance of 1270 pF at 25 V drain-source gives a rough figure for the gate-drive power budget in high-frequency designs.
Sourcing an obsolete part
STMicroelectronics lists the STP16NS25FP as Obsolete. No direct replacement or successor order code is published in the available records. Buyers should verify stock position before committing a production schedule, as lead times and lot traceability vary with surplus inventory.
