2N1711 transistor replacement

That's because it's an ancient transistor.

If you need this to build some circuit found somewhere, make sure the rest of the parts are available.

I need this to repair some old welding device... It's about 10 years old...

Graham

It's still in production and not hard to find.

See findchips.com for some sources... since Newark has it, you should be able to get it from Farnell in Europe.

Easily 40.

This is the info I have on it:

2N1711 Si NPN 50V 3W 1A 70MHz, GP Amp, TO-39

It shouldn't be too hard to find a substitute, such as a 2N2219A or 2N3053.

They have lower voltage ratings.

What about 2N3019. This one should be OK.

My vrt databook says ...

2N1711(S) Si-N, general purpose, 75V, 0.5A, 0.8W, >70MHz = BC140, BC141, BC300, BC301, 2N1990

2N1711A,L (2N1711: 1A, 1W) = BC140, BC141, 2N1990, 2N2102, 2N2405

2N1711B (2N1711: 120V, 1A, 1W) = 2N2102, 2N2405, 2N3019

I've not met that one before. Looks promising. May not be any easier to source of course !

I have about 20-30 pieces (used) from Ericsson PBX equipment cards. Yes it is also available at eBay UK.

For Ante:

be aware that they may have been removed to gain access to the heatsink they had. This would have been required if they were dissipating any higher amount of power. The heatsink may have been a finned 'hat' or a large hollow bolt with a threaded part to attach to an external h/s plate.
