Digikey offers 4 different parts for the PBSS5350X: 1) PBSS5350X, 146 and 2) PBSS5350X, 135 and 3) PBSS5350X, 115, and finally 4) PBSS5350X, 147. All of these have different Digikey part numbers and separate stock. But all of the listings are identical except for the number after the comma.
The Nexperia Datasheet doesn’t show any of this.
What is the difference? What does the number after the comma mean?
