While sorting some boxes of old junk I found a resealable plastic bag full of tiny paper envelopes, a couple of which had Tektronix brand labels.
One envelope was marked: Tektronix 152-0177-00 Germanium tunnel diode, the others were: 152-0434-00 and 152-0465-00
Anyone know if its possible to find info on these parts? I've tried putting "152-0177-00" into google, there was only 2 pages of hits and no data that I could find.
TIA.
Those are hard to find, IIRC they're used in the trigger circuit of many older Tek scopes.
My 465 uses a couple of tunnel diodes - maybe I should keep the spares safe just in case.
For some time I've been trying to find a "round tuit" to build a dip meter, with a couple of tunnel diodes in the parts drawer a tunnel dipper becomes a possibility.
152-0177-00 10maTD
Germanium tunnel diode, the
152-0434-00 in the snapoff section of the "don't you dare use thisin a new design section" , no info available
and 152-0465-00 says it's a quad, no info available
Thanks - the 10mA info is useful
One of the envelopes was marked "quad - do not seperate".
There's a little TD stuff on this site:
Maybe the authors of the page have more. Also check with:
