2. 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].

3. 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.

Synonyms

  • SC-90: JEITA (EIAJ).

  • SOD-323F-2: Mouser[6].

  • SOD-323FL: Rohm[8].

  • UMD2: Rohm[8].

Warning Rohm uses the name SOD-323FL to refer to the same package as many other manufacturers call SOD-323F[8]. Central Semiconductor also uses the package name SOD-323FL, but this refers to a different variant with different sized leads (see below).

4. 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 other[3]. This improves the heatsinking of the package even more than that of the SOD-323F variant.

5. SOD-323HE

The SOD-323HE is also known as SC-108B (JEITA) or TUMD2M (Rohm)[4].
