PIN Diodes used in Tek products

Gary Robert Bosworth
 

Does anyone know the name of the manufacturer and their part number for the PIN diodes used in the DC508A frequency counter? So often, Tektronix used themselves as the source and did not specifically call out what part was used. Perhaps they did this because they used selected components. The component listed is rated at 100V and 100mA, but that is of little help to me since I do not know who made it. Anyway, I need the real part number for CR2213 and CR2214 used in the 1.3GHz input amplifier of the DC508A. Any help would be greatly appreciated.

HP made that diode. HP Part number is 5082-1779. At some point this was
spun off into Avago (later Broadcom). The same diode is used in the DP501
prescaler. I subbed mine with 5082-3080 which was available new from Mouser
at the time. Looks like it's now obsolete.

Gary,

You might look at the Microchip/Microsemi GC4410-115-2 or UM7301B to see if they come close to what you could use. But be prepared to hand over some cash.

Greg Muir
 

Dave,

While looking at diode data for Gary I noticed that your 5082-3080 part has a standard part number of 1N5767. This device is available.

Gary,
I deleted the email where you posted the part number you are trying to find, but I have a few 152-0125-01, 4.7 ma. tunnels; they are replacements for 1N3717 and TD-3A, I am told. I used them for a pulser I made, and they worked fine for my application. If they can help you, let me know.
Best regards,

Gerry: At this time, I am only interested in purchasing PIN diodes and
possibly a couple Hot Carrier diodes. I do not need tunnel diodes at this
time. Thank you for the offer. I am sure that tunnel diodes will not be
available in the future when I will need them. Such is life.

Each of these diodes is extremely different from the others. It is
critical to not only use the proper type of diode, but the correct part
number as well. Using the wrong part is a good way to dig yourself into a
technological bottomless hole.

That's great that it's still available!
I can't vouch for it's substitution in the DC508A circuit but it appears to
work okay in the DP501.
It's also priced about 5x higher than it was when I bought mine ten years
ago.

Miguel,
The GE Tunnel Diode Handbook (from 1961) describes tunnel diodes and back diodes and can be downloaded online. The Micro-semi PIN Diode Circuit Designers Handbook is, likewise, available. Outside of knowing that Gunn diodes are used for making microwave oscillators, I have no background with them.

Dave,

In reference to your comment regarding the sky-high pricing of the 1N5767, it's become a little tough to find any PIN diode that has reasonable characteristics coupled with a price these days. While looking at some of these items I was surprised to find others with tags as high as $115.00 for comparable diodes to the aforementioned.

What I also noticed was that most of the original manufacturers are no longer producing the original diodes. Instead some of the parts have been picked up by others who probably have to bear the cost of a line startup for production. Then there are the other companies who were the original producers who were snapped up by bigger companies (big fish eating little fish) or investors who needed to get a decent return on their investment so, obviously, the money had to come from somewhere.

Many of my suppliers who used to hand out catalogs and now believe it is easier to surf their vast stock online have forced me to keep a few of those older catalogs for quick searching and component comparisons. It is quite a shock to then compare prices of devices and how they have changed even only over a couple of years.

While browsing Tunnel diodes I found this interesting article covering Russian TDs...

if it helps I found a guy on Ebay selling groups of 3 for 10 bucks. It appears that he has 12 available a the moment

I did notice that listing. I sent him a note mentioning that the 1N5767 is not obsolete.

Hi,

What are the differences between:

Tunnel diodes, Back diodes, Pin diodes, and Gunn diodes
Have a peek here: https://www.youtube.com/user/w2aew/videos for some useful tutorials about some of those diode types.

Brian.
