CSD25402Q3A: Unique Footprint

Part Number: CSD25402Q3A


In one of my projects, i had to use a P- Channel FET in a dc-dc converter circuit. Unfortunately, the one i selected, CSD25402Q3A, doesn't withstand my input voltage of 24-26V. The strange thing i came to notice is that only Ti's P -FETs have this pin layout - Pins 1-4 Source, 5- 7 Drain. Rest of the manufacturers layout is the direct reversal of this one - Pins 1-4 Drain, 5 - 7 Source. Doesn't all these parts follow some unique standards? Does this happen with other components too? Now i'm not able to find an alternate for CSD25402Q3A, due to this pin layout.
