Hello Xiao,
Please be informed that diodes are no longer in NXP's portfolio.
NXP has divested its Standard Products business on Feb 6th 2017. There is a standalone company called “Nexperia”, headquartered in the Netherlands, and is one of world-class leaders in Discretes, Logic and MOSFETs.
You may try to re-enter your inquiry at the Nexperia support web page: www.nexperia.com/support.
Best regards,
Tomas
