When receiving a shipment of Vishay GSD2004W-E3-08 diodes, you may find them marked “B6 P8” despite the datasheet claiming they should be marked B7 P8. Is this an error?
No error to worry about. The ‘B6’ marking is still valid for the part, denoting a diode made before November 2023. The marking has since been updated on newer products, and older versions of the diodes still conform to the same specifications.
