DESCRIPTION
Lot of 10 new old stock vintage stud-mount rectifier diodes marked with a boxed "S" logo and "337512." The pictured unit also carries "7326." Each has a metal hex base, a threaded mounting stud and a top lead ending in a solder eyelet. They came from a parts bin labeled "Silicon Controlled Rectifier / Diode." These parts have only two terminals (stud and eyelet), so they are diodes, not gate-controlled SCRs. The plating is clean, with light storage marks on the hexes and eyelet leads, as pictured. You will receive 10 pieces.

Stud-mount diodes like these bolt directly to a heatsink or chassis and are used in power supplies, battery chargers, welders, motor controls and other rectifier circuits. The part number 337512 appears to be an OEM or house number. We could not match it to published manufacturer ratings, so these are best suited for exact-replacement repair where the original part number is known. A lot of 10 covers full bridge rebuilds and spares.

Features:
10 stud-mount rectifier diodes
Hex base with threaded mounting stud
Solder-eyelet top terminal
Marked "337512," exact replacement for equipment using that number
New old stock, never installed

Compatibility:
Direct replacement where the original part is marked 337512. Voltage, current and polarity are not marked on the parts, so measure them and match the ratings to your circuit before installing. Thread size and hex dimensions are as pictured. Measure before ordering if fit is critical.

Q&A
Q: How many diodes are included?
A: 10.
Q: What are the voltage and current ratings?
A: They are not marked, and we could not find published data for 337512. Match them to your original part or test before use.
Q: Are these SCRs?
A: No. They have two terminals, so they are diodes. The SCR wording on their storage box is only the box's label.
Q: Which terminal is the cathode?
A: Polarity is not marked. Check with a meter's diode test before installing.
Q: Are they matched?
A: No. They are sold as a lot of 10 and have not been tested or matched.
