TOLL:
Much bigger contact area results in lower current density, avoiding
electro migration even at higher current level and higher temperature
->Improved Reliability in High Current Applications

Summary
Why TO-LeadLess?
 A leadless package with
60% space reduction
 Highest current capability: up to 300A
 Very low RDS(on) – up to 30% lower RDS(on)
 Enables a visual inspection due to Tin plated grooved leads
 Better EMI due to reduced parasitic inductances (cut by half)
 High reliability due to improved solder contact area – reduced
electro migration
 Reduced BOM: Smaller board, less drivers, less MOSFETs
