Maybe? :SMBJ58CA littlefuse transint supressor diode in DO-214AA package.

You should specify where did you take those elements from. What is their theoretical purpose.

  • \$\begingroup\$ Not likely. SMBJ XXX C A diodes have a cathode band and a Littelfuse logo on them. \$\endgroup\$ – Huisman Jun 15 '19 at 9:46
  • \$\begingroup\$ @Huisman bi-directional wouldn't have a cathode band, It could any other manufacturer making equivalent. \$\endgroup\$ – Marko Buršič Jun 15 '19 at 12:05
  • \$\begingroup\$ looks like taken out from right side of PCBA \$\endgroup\$ – Curious KP Sep 18 at 5:07
