●Your company has Critical Process Change Notification requirements on products that you buy from MICROSEMI/MICROCHIP. This letter is to notify you that part numbers are changing for our SiC Diode devices in Dual-Diode configuration and SOT-227 packages. All new part numbers are pin compatible replacements.
●The old part numbers will no longer be available from MICROSEMI/MICROCHIP, and the new part numbers will replace the old part numbers in the next price book edition and our upcoming catalog. Some of the older part numbers (APT2X) were previously discontinued with PDN#19-021. Associated data sheets shall be replaced on the website in a very short time as well.
●Description of Change:
■SiC Diode devices in Dual-Diode configuration and SOT-227 package part numbers are changing as shown in the table below.
●Reason for Change:
■Standardized SiC part numbering MSC2X*SDA*J will replace MSC2X*DC*J. APT2X*SDA*J parts are being replaced by the next generation of SiC devices.
