I can't seem to find what type of transistor this is based on the markings. It's broken, so I need to replace it. It is in a Chrysler Jeep radio from 1995. The letters are "CBRP". Thanks. enter image description here

  • \$\begingroup\$ How do you know it's broken? What is it supposed to do? What is it doing? \$\endgroup\$

  • \$\begingroup\$ Is it related to a CB Radio antenna, used within cars? \$\endgroup\$ Sep 13, 2018 at 15:48
  • \$\begingroup\$ @MCG The radio isn't turning on and I've been doing a lot of troubleshooting. This transistor has a crack between the "R" and "P" so I'm going to try to replace it. \$\endgroup\$ Sep 13, 2018 at 15:52
  • \$\begingroup\$ @Michel Keijzers No, It's just a regular car radio/cassette player. \$\endgroup\$ Sep 13, 2018 at 15:54

1 Answer 1


My guess would be a BCX68-10 from Infineon. It also has a SOT-89 package and has the marking "CB". If this is true then it is an NPN BJT, 1A collector current, 20V Vce rated. Datasheet here:


Not certain about this though, as the diagram doesn't quite match up:

  • \$\begingroup\$ Thanks for the link. I'll track one down and try it. I'm going to leave the question unanswered for a bit to see if others have an idea. \$\endgroup\$ Sep 13, 2018 at 16:00
  • \$\begingroup\$ Sure thing. Like I said things don't quite match up, so I'd be hesitant to accept this answer myself. Keep us posted! \$\endgroup\$
