About this part
The 2N3053 is one of the few parts in this drawer you could call a workhorse. An NPN silicon medium power transistor in a TO-39 can, rated in the region of 40 volts and 700 milliamps, with enough dissipation in the metal package to drive a relay, a small motor or the output stage of a modest amplifier without complaint. It has been second sourced by nearly everybody, which is why it survived so long in service manuals as the obvious answer when a general purpose medium power NPN was wanted.
These are the Motorola parts, and the stock paperwork that came with them carries the NATO stock number 5961-00-985-9073, which is how the same device is ordered through a military supply system. That provenance is worth having if you are working on equipment that lists parts by NSN rather than by part number, because it closes the loop between the two without a cross reference.
Two are on the shelf and each is marked 2N3053 on the can. Secondary lot and date coding varies between the pieces, which is normal for stock assembled from more than one production run and is not a sign that anything is wrong. The price is for one transistor.
Questions about this part
What is the 2N3053 normally used for?
General purpose medium power switching and amplification: driving a relay or a small motor, the driver stage of an audio amplifier, a regulator pass element in low current supplies. It is rated around 40 volts and 700 milliamps, and the metal can gets rid of enough heat to make that usable rather than theoretical.
What does the NSN on the paperwork buy me?
A direct link between this device and the way military and aviation systems order parts. If you are working from a document that lists 5961-00-985-9073 rather than 2N3053, this is that item, and you do not need to prove the cross reference yourself.
Why do the two pieces look slightly different?
Secondary lot and date markings vary because the stock was assembled from more than one production run. Both are marked 2N3053 and both are Motorola. Cosmetic variation in the secondary coding is normal for old stock and says nothing about the device.
Is the price for one or for both?
For one transistor. Two are on the shelf and they are sold individually, so set the quantity to two if you want the pair.
