Worked perfectly
Used to fix an old bose wave radio with failed transistor.

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

"Definitely Great Power Transistors for all & everything"
Excellent Great Quality Power Transistors... We tested with our Longruner Multi-function Tester -TC1 and all "10 Transistors" passed the test with a good parameters from manufacturer.... We are so happy to have them for our Science Projects of Electronics ((( field of Physics ))).Fast shipping too. . . We recommended 100% . . . A++
