Filed under schematics, this 97.5 KB PDF labelled 25tts-fp appears to be a component datasheet for a variant of the 25TTS power device series. The -FP suffix probably denotes a specific package style, though the name alone does not confirm it. There is no board or equipment reference. Use the sheet for pinout, mounting outline, voltage and current limits, and thermal data when checking or replacing a power switching part. Package variants differ in tab isolation, so verify the physical part.
