Seeking the below differences in the below as we compared with what we have bought previously. please advise.

Lead frame structure different.

Is there any official documents or PCN to support this change? Does this affect the application of the parts? thanks

Left picture is what we previously bought, and right picture is what we recently bought.

Hi, Calvin,

The figure on the right is our current leadframe.

This change to the internal leadframe is transparent to customers.

Best regards,

Don
