Review SYLVANIA GTE Lot Rare 2/1 Germanium Pnp Transistors Vintage Datasheet

The 2N139 Sylvania Germanium Transistor, as depicted in the 1956 datasheet issued by GTE, is a vintage electronic component that holds a significant place in the history of electronics. This transistor is a type of germanium junction transistor, known for its distinctive characteristics and applications in various vintage electronic devices.

The 2N139 transistor is a two-terminal, three-layer device, consisting of a thin layer of intrinsic germanium sandwiched between two p-type layers. This structure allows for the control of the current flow between the emitter and collector terminals by applying a small voltage to the base terminal. The device operates in both common-emitter and common-collector configurations, making it a versatile choice for various amplification and switching applications.

The 1956 datasheet offers detailed specifications for the 2N139 transistor. It has a maximum collector-emitter voltage (VCE) of 125V, a maximum collector current (IC) of 300mA, and a maximum power dissipation (Pd) of 0.375W. The device also exhibits a base-emitter voltage (VBE) of around 0.6V at 1mA of collector current.

Despite its age, the 2N139 Sylvania Germanium Transistor still retains its charm and appeal among electronic hobbyists and enthusiasts. Its unique sound and tone characteristics make it an essential component in vintage audio amplifiers, oscillators, and other audio applications. Additionally, its low cost and availability on the vintage electronics market make it an attractive choice for DIY electronics projects and educational purposes.

In summary, the 2N139 Sylvania Germanium Transistor is an iconic electronic component with a rich history and a wide range of applications. Its vintage characteristics and versatile performance make it a valuable addition to any electronics collection or project.

Details:

I sell quality new or nearly tested merchandise. Not surplus junk you are a 1 er big asset.

Equipment was delivered in great condition.

I have been selling many of the leftover inventory from a retired local dealer. Unit performs as advertised.

Flat rate charges may be less or more than actual shipping costs.

This has been a distinct pleasure. Now and in the coming weeks. Rarely, an item may be offered for parts or rebuild and would clearly described as such.

Incredibly well packed item, precise and prompt communication, mint-condition item a positive overall experience.

Whether or not an article is new, I use the same care inspecting, detailing restoring it, as preparing listing you are reading now.

You are a model. Thanks finally a piece of exceptional test equipment.

The true equivalent may cost several times more. Shipping I expect to hear from the winning bidder within 48 hours.

I charge export papers fees for buyers outside north America.

I will round up to the next dollar or two cover calculator errors, delivery confirmation, gas and sundries. Item was shipped quickly and just as described, honest dealer.

As described. Unless I use a flat rate, do my best to charge as exact shipping possible.

Received items as described. First class packaging. A pleasure to deal with.
