Failures of CSD18563Q5A

Other Parts Discussed in Thread: CSD18563Q5A

Hi All,

   I am not sure if this is the right place I should ask this question, if not, sorry for inconvience!

   Our company have purchased total 80pcs CSD18563Q5A(first lot 60pcs and second 20pcs). We used more than 20pcs parts in the first lot on our PCB board. During testing, we found 2pcs CSD18563Q5A failed, the S electrode and G electrode were shorted. so we removed the CSD18563Q5As on the other PCB board which have not been powered yet, then we used mutimeter tested all removed prats, and also found 2pcs had same phonomenon, S and G shorts. That means there are 2 failures found after applying power supply on the board and 2 failure found even without applying power supply. it really concern us. the project was pursed casue we really worry about the reliability of these CSD18563Q5As. Could you kindly advise if these CSD18563Q5As do have quality issue and if you have ever encounter any similar failures before? or there were other possible reasons which can casue this kind of failure? Thanks a lot!

   Have a nice day!

 

Best regards!
