I like these parts.  I hope Infineon keeps making them for a long time.

SOT143:

Element[0x00000000 "" "" "" 0 0 0 0 0 100 0x00000000]
(
        Pad[-4700 -2740 -3900 -2740 4000 1200 5000 "1" "1" 0x00000100]
        Pad[-5700 3740 -2900 3740 2000 1200 3000 "2" "2" 0x00000100]
        Pad[2900 3740 5700 3740 2000 1200 3000 "3" "3" 0x00000100]
        Pad[2900 -3740 5700 -3740 2000 1200 3000 "4" "4" 0x00000100]
        ElementLine [8200 6240 -8200 6240 1000]
        ElementLine [-8200 6240 -8200 -6240 1000]
        ElementLine [-8200 -6240 8200 -6240 1000]
        ElementLine [8200 -6240 8200 6240 1000]
)

This was generated with footgen, and pin 1 was widened using emacs. I
have soldered BF998s to this footprint.
