Product Overview
Vintage 2N5961 Gold-Lead Small-Signal NPN Transistor – Unused NOS
This early-generation silicon transistor reflects the construction style used in laboratory and instrument electronics, featuring a rectangular epoxy body and gold-plated leads arranged in a straight inline pattern. Its format aligns with components found in late-20th-century analog and RF designs, making it appealing for period-correct restoration work or exploratory bench projects.

Product Overview
The 2N5961 is a JEDEC-listed NPN small-signal type known for low-noise characteristics, general-purpose amplification, and switching roles in early solid-state equipment. This specimen uses the uncommon block-style plastic package, with molded E-B-C identifiers on the face and gold-plated leads selected historically for corrosion resistance and stable electrical contact. Its markings include a circular logo with an internal cross motif and hand-applied color bands typical of period sorting practices.

Frequently Asked Questions
What distinguishes this version of the 2N5961?
It uses an early rectangular epoxy body and gold-plated leads rather than the later TO-92 shape, reflecting its vintage construction era.
Are the lead positions labeled?
Yes, the front of the package includes molded E-B-C lettering indicating the terminal arrangement.
Why are gold-plated leads notable?
Gold leads were favored for stable, low-resistance contact in laboratory and precision analog applications.
Is this style suitable for restoration projects?
Yes, its period-correct package and markings align with components used in older instruments and equipment.
You can combine its restoration value with the gold-plated lead format when placing it into a vintage-style inline socket on your bench assembly.
