Does anyone know of a method of either locating or finding information about transistors that were manufactured in 1972? I am specifically interested in locating or finding info on two transistors; their codes are: 2N5809 and 2N9614. I can't seem to find any supplier that has them so I am presuming they are no longer manufactured. Thanks for whatever help you can give me.

Can't even find them in Towers. ;-)

2N5809 =====
Mil Spec
The military stopped using them in 1999...
The above links found here
Sure that numbers right? No hits using Google is unusual. Usually someone wants to sell you the data!

Ron-
The 2N5809 is a small signal plastic case low noise, hi gain transistor typically by Motorola used for audio applications. I used these in the early 70's with good success. As I recall, hfe is on the order of 250, Vce about 30v. I may have one or two left.

According the to the Mil spec I posted types 2N5806 to 2N5809 are "Silicon bi-directional triode thyristor" with voltage ratings of 200-600V
It might help if you told us why you want to know. Repairing something? Building an old kit?

Not the exact thing, but, if used wisely, may help you for one of them.

What are they used in? If you're trying to replace them, it may be easiest to look at the circuit and guess on a suitable sub.
a 2n5809 is a triac, 600v or btx94
Sounds wrong for a lie detector.

Take another look. Could the second one be a 2N961A? I don't think the JEDEC numbers were that high in the early 70s.

My old '69 Motorola Manual stops at the 2N5500 point. The 2N5809 might be a valid number for that time period. But it's not in the Moto manual. :-(
the 2n5809 is not a transistor but rather a hefty stud mount Triac, if my memory serves me... around 30 or 40 Amps. the 2n961 is an RF/IF PNP Germanium transistor, metal can TO18... I used them in some ham radio projects in the late 60's. .... there is no 2n9614.... check the number again.

I have the second edition of General Electric transistor manual , the highest listed are 2N3524 , 3N86, roma
Using Yahoo (the only search engine IMHO) I found this for "2n5809"
Part Number = 2N5809 Description = Triac Manufacturer = Various V(DRM) Max.(V)Rep.Pk.Off Volt. = 600 I(T(RMS)) Max.(A)On-State Cur. = 25 @Temp. (°C) (Test Condition) = 80 I(TSM) Max. (A) = 200 @ t(w) (s) (Test Condition) = 16m I(GT) Max. (A) = 120m V(GT) Max.(V) = 4.0 I(H) Max.(A) Holding Current = 100m I(D) Max. (A) Leakage Current = 2.0m @Temp. (°C) (Test Condition) = 115 V(T) Max. (V) = 1.6 @I(T) (A) (Test Condition) = 35 Package = TO-208var1/4
I couldn't find anything on the other one.

NTE's cross for the 2N5809 is the NTE5547:
The 2N961/46 and 2N961 both cross to an NTE160:

Please remove one 'i' from my address when replying by email.
Neither can I find anything on a 2N9614. My data books go back to
1968...nothing in the 70's was higher than 2N6xxx that I can find.I recommend the original poster take a closer look at that transistor (thyristor?) with a microscope and get a better read on the part number.
He is from Canada, perhaps he can contact me directly if he is on the west coast. I'm in Vancouver, BC.

The 2N9614 is mentioned in a patent as a PNP Transistor.
