- Symbol:
ESD249B1W0201E6327XTSA1 - Footprint:
Diode_SMD:D_0201_0603Metric - 3D model: 0201, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.3 mm nominal 01005 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
