It came from a parts bin labeled \"Silicon Controlled Rectifier \/ Diode.\" This piece has only two terminals (stud and eyelet), so it is a diode, not a gate-controlled SCR. The plating is clean, with light storage marks on the hex and the eyelet lead, as pictured.\u003cbr\u003e\u003cbr\u003eStud-mount diodes like this 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 this is best suited for exact-replacement repair where the original part number is known.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eStud-mount rectifier diode with hex base\u003cbr\u003eThreaded mounting stud for heatsink or chassis mounting\u003cbr\u003eSolder-eyelet top terminal\u003cbr\u003eMarked \"337512,\" exact replacement for equipment using that number\u003cbr\u003eNew old stock, never installed\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eDirect replacement where the original part is marked 337512. Voltage, current and polarity are not marked on the part, so measure the diode and match its ratings to your circuit before installing. Thread size and hex dimensions are as pictured. Measure before ordering if fit is critical.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A\u003cbr\u003eQ: What are the voltage and current ratings?\u003cbr\u003eA: They are not marked, and we could not find published data for 337512. Match it to your original part or test before use.\u003cbr\u003eQ: Is this an SCR?\u003cbr\u003eA: No. It has two terminals, so it is a diode. The SCR wording on its storage box is only the box's label.\u003cbr\u003eQ: Which terminal is the cathode?\u003cbr\u003eA: Polarity is not marked. Check with a meter's diode test before installing.\u003cbr\u003eQ: Who made it?\u003cbr\u003eA: It carries a boxed \"S\" logo. We list it as unbranded because we have not verified the maker.\u003cbr\u003eQ: What does 7326 mean?\u003cbr\u003eA: It is likely a date code, which would mean 1973, week 26, but the maker has not confirmed it.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003eItem is new old stock, sold as pictured.
