Overview
SOD-323 (Small-outline Diode 323) is a family of 2-lead SMD component packages, commonly used for diodes.
The are four variants, with the key differences being:
- SOD-323: Bent leads.
- SOD-323F: Flat leads (better heatsinking).
- SOD-323FL: Flat leads, with one longer than the other (even better heatsinking).
- SOD-323HE:
Solderability: Reflow is recommended. Easy to solder by hand.
Pitch: 2.2mm1

SOD-323 (Standard Variant)
SOD-323
is a 2 lead, SMD component package commonly used for diodes. Without any other suffixes, SOD-323
typically refers to bent lead variant, also know as SC-76
(JEITA)1.

SOD-323F (Flat Lead Variant)
The SOD-323F
is a variant which has flat leads instead of the bent leads in the standard SOD-323
. It has the same body dimensions as the standard SOD-323
.

WARNING: Rohm uses the name SOD-323FL
to refer to the same package as many other manufacturers call SOD-323F
4. Central Semiconductor also uses the package name SOD-323FL
, but this refers to a different variant with different sized leads (see below).

SOD-323FL (Central Semiconductor Variant)
Central Semiconductors version of the SOD-323FL
(the FL
is presumably an acronym for Flat Leads) is another variant of the SOD-323
with flat leads, except one of the leads is much longer than the other7. This improves the heatsinking of the package even more than that of the SOD-323F
variant.
