Overview
SOD-523
(Small Outline Diode 523, JEDEC) is a 2-lead SMD component package.
Synonyms:
- CASE 502 (onsemi, STYLE 1 has diode polarity mark, STYLE 2 does not1)
- SC-79 (EIAJ2)
- SSMini2-F5-B (Panasonic3)
Similar To:
Pitch: 1.40mm
Solderability: Reflow is most suitable. Possible to hand solder/reflow as long as experienced.
Package Dimensions:
Typical PCB Land Area: \(2.58mm^2\)
(2.15x1.20mm)2
Common Uses:
- ESD protection diodes.
- Schottky diodes.
The SOD-523 package size (excluding height) of 1.65x0.80mm (length x width) is very similar to the 0603 chip package size of (1.55x0.85mm). SOD-523 is smaller than the SOD-323 package, but larger than the SOD-723 package.
