2SC5200/2SA1943 Toshiba or Fairchild

Rob_S · 27th May 2009, 04:52 PM

I'm looking to build an amp using 2SC5200/2SA1943 devices as the outputs, is there much difference between the two manufactures Toshiba/Fairchild?

Also good places to purchase, that would be cheap but original devices.

thanks
Rob

I will know in the next few weeks how the Fairchild devices work, or at least if they don't work. I selected the Fairchild TO-220 devices from DigiKey for the TGM amplifier. I don't need the power levels offered by the larger T03 packages. I also suspect the TO-220 packaged devices are not targeted for fakes.

From digikey they are quite reasonably priced if I remember.

I don't know which is better. They have different case choices and the Fairchilds are a little cheaper, but they're all pretty cheap anyway.

Digi-key is a good safe source for the Toshiba's. They get them directly from Toshiba, but sadly they don't carry many different devices. They also list the Fairchilds, but they never seem to have stock. I haven't looked for a while though.

I may be mistaken but didn't Fairchild used to be Samsung? Samsung once had an excellent semi fab production, particularly small signal stuff. My experience with Fairchild's Q-fet hex type power fets is quite positive.

I'm not as familiar with their power BJTs.

BTW, Mouser seems to have lots of Fairchild stock.

Hi Rob_S

Do a search to this thread here :

Where in Europe do you buy your 2SC5200-O and 2SA1943-O for AAK's Symasym boards ?

I hope this helped you.

Best regards

From what I remember they did buy part of Samsung Semiconductor's portfolio. I think this was mainly discrete devices and integrated circuits, leaving Samsung to produce DRAM and other memories

Thanks rephil for the UK supplier for the Tosh devices.

From others comments there looks to be little difference between the quality of the devices?

thanks again
Rob
