Vintage Electronic Component
This transistor is New Old Stock. It has not been installed but may show minor cosmetic evidence of long-term storage, age, oxidation, or handling. Original retail packaging is not included. Please review all photographs carefully for the exact markings, terminal condition, and component included.
DISCLAIMER
This item is New Old Stock and has been stored for an extended period. It may show minor cosmetic wear, oxidation, discoloration, scratches, or other evidence of storage and handling. No claim is made regarding compatibility with any particular circuit or equipment. Buyers should verify the exact part number, electrical ratings, terminal configuration, heatsink requirements, and application specifications before installation. Ships fast with tracking. Thirty-day returns are accepted; buyer pays return shipping.

COMPATIBILITY & CROSS-REFERENCE
The 2N3055 is a JEDEC-registered NPN silicon power transistor in a TO-3 (TO-204AA) metal package, second-sourced by many manufacturers. Registered ratings are 60V collector-emitter, 100V collector-base, 15A continuous collector current, 115W dissipation and a DC current gain of 20 to 70 at 4A. Its complementary PNP device is the MJ2955, and the two are commonly paired in push-pull output stages. The NTE and ECG aftermarket cross-reference house number for the 2N3055 is NTE130 / ECG130. Note that some variants such as the 2N3055H and 2N3055HV carry different voltage ratings — confirm the specific manufacturer's datasheet before substituting. The collector is electrically connected to the case, so the package must be insulated from a grounded heatsink where the circuit requires it.
