Package size
| Package | Also called | Body | Height |
|---|---|---|---|
| SOD-123 | SOD123 | 2.69 × 1.6 mm | 1.17 mm |

Nominal body size without the leads.
How to tell them apart
Measure the plastic body without the leads: SOD-123 2.69 × 1.6 mm · SOD-323 1.7 × 1.25 mm.
Look at where it sits: a small part next to a USB connector is often ESD protection or a Schottky diode; a 3- or 5-pin part near the power input is often a regulator.
The same code can mean different parts at different makers. The package narrows it down, so measure the body.
