Real Deal Toshiba, can't go wrong with Bojack.
The one I received are all the real deal Toshiba 2SC5200 and 2SA1949. I have used only two sets so far and they work a little better than I expected then I tested all I had remaining with a multimeter they all checked good. I also installed one of the 2SA1949,s into a Anytime at-6666 as an upgrade for the AM regulator and the 2sc1949 did exactly as intended, Upgrade.

Great amplifier transistors and good cost. Within component specs.
Excellent transistors, these work very will with my audio designs. Nice selection and cost. Happy with purchase.

Fake, counterfeits. Failed all tests.
Counterfeit [IMO] Failed miserably. I am now testing all incoming parts! NPN were not well matched IMHO >20% (I think within 10% or better is considered well matched) Both NPN and PNP fell way short of specified voltage ratings. (transistors normally exceed voltage ratings by a wide margin). Both NPN and PNP suffered secondary breakdown at only a fraction of rated parameters! Both NPN and PNP have inferior heat tab material. (probably about 1/5 the heat transfer capacity of OEM). Here are my results: hfe; PNP 120-125, NPN 90-110 (~>20%) [measured all] Secondary Breakdown failure: Both NPN and PNP shorted @ <2.5A @ <25V (<2 seconds). Failed at medium voltage and current not even close to the secondary breakdown limit area of the SOA chart! [tested one of each] Vceo: Both failed voltage tests; PNP @ 135V. NPN @ 185V. [tested one of each] I did not check them at 15A. No point in going any further if they are failing these tests. I took a chance because of conflicting reviews, allowing for novices that don't understand SOA limitations, and under time pressure. Very disappointed. I am repairing two professional sub-woofers that utilize ±95VDC unregulated supplies. Allowing for line voltage tolerance and possible remote generator operation, and a decent safety margin; they need to withstand 200V+ in operation plus a safety factor. They are marginally designed to begin with, and cannot tolerate replacements not meeting the minimum ratings of the originals. (These are the original part numbers, I was not substituting when I ordered these). Do not buy these, Regards, Mr KL

Los recomiendo solo que la primera vez no le entre la energía de lleno con un foco de carga
Cheque pesoo y beta interna de los transistores son de buena calidad
