Ex workshop spare parts and small manufacturing stock
ALL devices offered have been sourced through reputable local distributors such as RS Electronics, Farnell, WES and Rockby (Victoria) NOT direct import Chinese (often dodgy specification or even fake) devices
Yes, fakes! SANKEN high power (higher value) transistors in particular were a target for mostly Chinese manufacturers looking to make a quick buck with product that nowhere near meets the original specifications.
There are subtle differences between fakes and genuine devices externally and it can be challenging to determine if what is in your hand is genuine or a fake so here is a quick guideline ...
Non-destructive guidelines
The manufacturing batch code in genuine product is always 'centred'
The print on the front is slightly thicker and slightly smaller than a fake (hard to judge when you don't have a fake for comparison!)
The rear metal heatsink should be a slight frosty finish, not a mirror like finish!
The weight is important but very accurate, low weight measuring scales is something you don't tend to carry around with you!
The die on genuine product is much larger than that used in fakes, there is a weight difference of around 3 grams!
Non-genuine 2SC3264's weigh approximately 15g (smaller die)
Genuine 2SA3264's weigh approximately 18g (agreeing with the manufacturers specifications) - see my photograph with one of these transistors on the scales showing the weight of these transistors is exactly to spec - as if we would use fakes in our amplifiers of days gone by!
Destructive testing:
Of course you can "open it up" but then you have destroyed your expensive transistor!
We ONLY EVER purchased our stock from reputable local suppliers, those who's reputation relies on providing genuine product and of course, our clients expected/demanded that only verifiable genuine product was being used.
NEVER be tempted by "damn that's a cheap transistor" from China in particular, you will get "burned" - they are cheap for a reason, they are rubbish!
The transistors I am offering are low cost only because they are old stock from our business which has now closed down due to retirement - you will kick yourself if you miss out because these are "dirt cheap" GENUINE devices!
