hello for everyone
im newbe here, thanks for accept me
i have a problem with a part, kenwood ampl has some trait, i found on internet that is a something like a transistor, but maybe is a mosfet, it is the same?
how can i test and buy
the parts KENWOOD TRAIT N3Y 7131 and has 5 pins
the ampl has 10 of them with diff numbers but similar betwen them
pls let me know something
note. is an old amplifierfrom 10 years ago
thanks in advance

You need to get them from Kenwood.
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.
