[[User:Zenwizard|Zenwizard Studios]] found thirteen of these in a [[475]] and thirteen of those tested as having a parasitic reverse diode junction; a curve trace of the 151-0367-00 exhibiting a low reverse breakdown voltage can be seen in the images.
''The "parasitic diode" is very likely an artifact created by simple transistor testers, see the thread at https://groups.io/g/TekScopes/topic/101335545#201002''


A list of eighteen has been extracted from the [[Media:Tektronix_475_Oscilloscope_Service_Manual.pdf|Service Manual]] and is shared on the [[475/Repairs#Problematic Transistors|475 Repairs]] page.
