Subject: Create new TO252FET footprint for IRLR8743PbF
X-Git-Tag: telelco-v3.0~639
X-Git-Url: https://git.gag.com/?a=commitdiff_plain;h=ba16aec479010d51d1a17b1f1ef9dd8107ed2acc;p=hw%2Faltusmetrum

Create new TO252FET footprint for IRLR8743PbF

This uses the same geometry as the LD29150DT50R, but with a different
pin label and numbering scheme.

This also reverts the pin renumbering in the n-fet symbol.
