I lost the component lables KE 8J617 on my Raspberry 4

Do you know where I can get that component or what the name of that is (did a google search on the KE 8J617, that showed nothing)



  • Ah let me see. It is just a cap, C84 in the schematic: raspberrypi.stackexchange.com/questions/104596/….

    Thanks all. looks like its a 3216 47uF SMD capacitor. I'll give it a try. Its a 4GB Pi-4 that costs here in NZ over $NZ100, so worth while to give it a try, instead of buying a new one.

It is a TVS diode.

"A transient-voltage-suppression (TVS) diode, also transil or thyrector, is an electronic component used to protect electronics from voltage spikes induced on connected wires." https://en.wikipedia.org/wiki/Transient-voltage-suppression_diode
