Using the search feature here and even google not here I could not find any information on these power chips I removed from a Kenwood Sovereign amp I scrapped last week. Thought I would ask here if anyone has any links to simple amps that use these. Thanks
An externally hosted image should be here but it was not working when we last tested it.
Probably these; https://www.semicon.sanken-ele.co.jp/sk_content/std01n_ds_en.pdf
or the higher power version; http://www.semicon.sanken-ele.co.jp/sk_content/std03n_ds_en.pdf
TRAIT stands for Thermally Reactive Advanced Instantaneous Transistor. This means that the thermocouple necessary to compensate for temperature effects in power transistors is housed inside the transistor instead of the traditional place on the heatsink. This minimizes the time difference between actual temperature of the transistor and measured temperature on the heatsink. This improves the sound quality of the amplified signal.
TRAIT transistors have 5 pins instead of the normal 3 (Base, Collector, Emitter or Gate, Source, Drain for MOSFET's) TRAIT transistors, manufactured by Sanken Electronics, were used in the mid 1990s for the first time in Kenwood amplifiers. TRAIT is called K-Stat in the USA.

I think yours may be the STD01N/P or the STD03N/P
If your N3Y has a transistor marked P3Y near to it, then it's likely that you need an STD03N, which would probably be the Kenwood equivalent.
Alternatively SAP15P/M
