Product details

Obsolete — plan the BOM transition

The STF25N10F7 is listed as Obsolete. That means STMicroelectronics has stopped production, and the only supply channel is the independent surplus/broker market. If this part is on your active BOM, you need to qualify a replacement or secure a last-time-buy lot through a broker.

Low gate charge simplifies the driver

The 4.5 V threshold voltage at 250 µA means you need a full 10 V gate drive to hit the rated Rds(on) — a 5 V logic-level drive will leave the FET partially enhanced, so budget a 10 V rail or a gate-driver boost stage.

TO-220FP — isolated tab, no extra insulator

The TO-220 Full Pack (TO-220FP) package fully encapsulates the tab — it is electrically isolated from the drain. That saves the insulating pad and washer you would need with a standard TO-220, and it simplifies the heatsink attachment. The through-hole mounting suits point-to-point wiring or PCB designs where a soldered tab is acceptable.

Frequently asked questions

Is STF25N10F7 obsolete?

Yes, the STF25N10F7 is listed as Obsolete. STMicroelectronics no longer manufactures it. Supply is limited to surplus and broker channels.

What is the replacement for STF25N10F7?

Your design team will need to qualify a 100 V N-channel MOSFET in TO-220FP with similar Rds(on) and gate charge. Look at ST's current STripFET F7 series or comparable parts from Infineon, ON Semiconductor, or Vishay — the key matching parameters are 100 V Vdss, 19 A Id, and 35 mOhm Rds(on) at 10 V.

Where can I buy STF25N10F7?

Because the part is obsolete, it is not available through normal distribution. We source it through our independent supply network — submit an RFQ and we will confirm availability and current pricing at quote time.
