Remaining Europe: Vintage Transistors / Diodes Collection
This site contains my collection of vintage transistors and diodes, most of them included with their original package or sleeves. The devices are produced in the late fifties and early sixties except the MOSFET's from Sony they where made in 1975. Enjoy the collectables and click on the picture links for more details. Suggestions regarding these transistors are welcome. I'm always looking for new semiconductor items to complete my collection, so if you would like to sell or exchange something, please contact me, jan@transparentsound.com.

| SA495 | Type | : | SA495, PNP Silicon Transistor |
|
|
Manufacturer | : | GEC Plessey Semiconductors "Semics" |
| Year | : | Early sixties | |
| Package, Case style | : |
TO-1, The SA495 is a PNP Surface Alloy Silicon Transistor produced in 1961 by GEC Plessey Semiconductors. I didn’t discover the difference between the SA495 and SA495A. This type has a full gold plated encapsulation, other devices could be different like metal colour or a combination of these two colours. |

| ST140 | Type | : | ST140, NPN Silicon Epitaxial Planar Transistor |
|
|
Manufacturer | : | Sinclair, brand labeled from Philco |
| Year | : | Early sixties | |
| Package, Case style | : |
?, In 1958 Fairchild marketed their first silicon diffusion mesa transistors to RCA, and then planar transistor in 1959. In early 1960s the epitaxial growth technology is invented and adopted by many other semiconductor manufactures. The ST140 is a NPN Silicon Epitaxial Planar Transistor from Sinclair, although this company didn’t produce transistors but applied them in their own products. I think they brand labelled these devices from Motorola identical Van der Heem from Holland did with their semiconductors |
|
| Spec's | : | Vceo=-25V, Vcbo=-25V, Hfe=15-40, Ic=-50mA, Icbo=-1uA, P=680mW, ft=700MHz(max), Cobo=2.2pF | |
