Subject: [TN] Cracks in the body of glass diodes (JANTX1N4148UR1)

Good Morning,

In a certain number of SMD diodes we have detected what we consider as a 
crack in the glass body of the diode. This condition was already present in the 
diodes packaged in a reel, that is, before mounting in the PWAs.

What we cannot determine yet is if this condition could be acceptable. Could 
you help us through your valuable opinions?

PD: I have sent 3 photographs to Steve Gregory.

Thank you in advance.
