1N007 Diodes?

[ron944]

Hi, I need to replace some 1N007 Diodes and cannot find anyone that carries them or who manufactured them. Is there a substitute that will work. Thanks

Could they be 1N4007 ?

What are they used in and as ?
Picture maybe.

They are smaller than a 4007. I have seem them referred to on line in many posts. I don't know if the ohms are different or if I can use 1n4007's in place of them.

Hi Ron... must be honest, I can't recall ever seeing that number.

If they are used in a normal PSU for example then providing the current rating of the 4007is OK I can't see a problem.

If they were in a switchmode PSU then a high speed or fast recovery diode is called for.

In this tube preamp two are used in series off of a poly cap going to a solid state voltage regulator. They were used in alot of guitar amps. etc. I think they may have been discontinued, just need to know if there is a substitute.

I'm sure 1n4007 will be fine (1000v PIV rated) if it's a normal diode.

Can you refer me to circuit using one or post a circuit up... just in case it's something like a zener diode... just with you mentioning a voltage reg.

Every case I have come across online seems to be a typo of the 1N4007 specifically.. In 35yrs of career and tinkering I have never heard of nor encountered a 1N007, no data sheets I can find turn up under this number either.. It would have to be extremely obscure if it exists I guess.

Common silicon small signal diodes: 1N914, 1N4148, 1N4150
Common germanium small signal diodes; 1N34A, 1N60, 1N270, OA71, etc..

on small parts it's common to drop the 1N4 designation since it's obvious to most.

It appears that "Four Star Electronics and "DERF Electronics Corporation" have them. They both are wholesalers dealing in hard to find discontinued parts. They show that "Vishay" was one of the manufactures.

Very strange that they both quote 2708 pieces as being the quantity available - this leads me to believe that they are accessing the same data base. I have not been able to find a single data sheet anywhere for this part leading me to still believe it may be a common typo. Derf lists both Motorola and Vishay as former sources for this mystery part.
