Diodes SBR10U45SP5-13

A 45 V super barrier rectifier in PowerDI5. The datasheet specifies a maximum 0.42 V forward drop at 8 A and 25 C, or 0.47 V at 10 A and 25 C. The 10 A rating depends on mounting and temperature conditions; it is not an arbitrary-board rating. Manufacturer datasheet.

The -13 ordering code is 5,000-piece tape and reel; actual factory marking is S10U45S. The model's full-MPN mark is an optional virtual identification aid, not a factory marking. No cold-temperature forward-drop guarantee is inferred from the 25 C specification.

Assets and alignment

The conventional rectifier symbol has logical pins K=1 and A=2. The KiCad footprint follows the datasheet page 5 land dimensions: a 4.860 by 3.360 mm cathode, two 1.400 by 1.390 mm anodes on 1.840 mm pitch. The two physical anode pads intentionally share number 2. Cathode is negative X, anodes positive X, seating plane Z=0.

The STEP and GLB are original nominal drawing reconstructions, not manufacturer CAD. Bounds are 6.510 by 3.966 by 1.100 mm. Mold taper, edge radii and internal die geometry are omitted. Keep plain and marked board models separate from the hero's nonphysical footprint and pin-label overlays. See provenance. The native KiCad candidate loads this footprint and resolves the STEP without model warnings; its 104-reference schematic/board check matches all 273 connected pins. The published hero was visually reviewed from top, oblique and underside views. Full native board rendering and cross-application visual parity remain separate checks.

When importing into a project, copy the STEP to the project's 3d directory to satisfy the portable ${KIPRJMOD}/3d binding, or explicitly rebind to your shared model library. Preserve the zero offset and rotation. A logical-pin current boundary must account for both physical anodes; declare the current split and select physical pad centers rather than silently choosing one.
