Si7900AEDN vs. Si7900EDN  
Description: Dual N-Channel, 20-V (D-S) MOSFET with Common Drain  
Package:  
Pin Out:  
PowerPAKr 1212  
Identical  
Part Number Replacements:  
Si7900AEDN-T1 Replaces Si7900EDN-T1  
Si7900AEDN-T1—E3 (Lead Free version) Replaces Si7900EDN-T1  
Summary of Performance:  
The Si7900AEDN is the replacement for the original Si7900EDN; both parts perform identically including limits to the  
parametric tables below.
