MMBT3906 vs. PMBT3906


#1

One question that came up recently was the difference in Nexperia part MMBT3906 and PMBT3906. Since we were not able to find this information we contacted the manufacturer and were able to find that these parts do not have any differences between them and that it was actually a change in part numbering when bringing the old part numbers up to the new Nexperia part numbers.

Here is the information from the manufacturer.

Confirming they are the same specification and the same die. This is another case of “same silicon, new part number” like we’ve done for some of the FETs, to bring the old Philips part numbers up to Nexperia numbering standards The “P” stands for Philips, while the ‘M” stood for Motorola (before they split off) There is no technical difference.
