Pin Count 8 + exposed pad
Pitch 1.20mm
Solderability Not suitable for hand soldering due to pads underneath the package. Suitable for hot air and reflow soldering techniques.
Thermal Resistance
  • \(R_{JC} = 0.4^{\circ}{\rm C}/W\)
  • \(R_{JA} = 40^{\circ}{\rm C}/W\) (max)

Common Uses High-power MOSFETs (e.g. with 300A current capability)


As far as I know, the TO-Leadless package is solely used by Infineon for a range of it’s high power MOSFETs. In this package, Infineon’s MOSFETs can achieve on-resistances as low as 0.4mΩ. It’s package size is 60% smaller than the D2PAK 7-pin package.
