SMD diode marking…uj41a
2 pole 4.15 mm L x 2.65 mm W
in a motor controller board 120 single phase to 3 phase
Board is a Sanken SPS065 PKG1
Any equivalent doide available ?
Hi,
Welcome to the Digikey tech forum. Take a look at Digikey part US1J-E3/5ATGICT-ND which is a diode of similar size and has the marking of UJ . I’m not sure how the markings are actually shown on your part and the part I listed is a guess. If you can post a photo that may assist in identifying what you have.
Here is pictures
Thanks for the photo, based on the markings and looking at page 3 here https://www.vishay.com/docs/88912/diodesgroupbodymarking.pdf it’s a good chance Digikey part US1J-E3/5ATGICT-ND is the diode you’re looking for .
Hi Steve,
Thanks, I will desolder and test out of circuit.
in circuit this diode shows response in both directions to DVM diode reading in both directions.
so possibly bad.
Regards.
Peter
