Synonyms n/a
Variants n/a
Similar To n/a
Mounting SMD
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)
Dimensions 11.7×9.9×2.3mm

3D Models n/a
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, Infineons MOSFETs can achieve on-resistances as low as 0.4mΩ. It’s package size is 60% smaller than the D2PAK 7-pin package.
