SOT-665 (Small-Outline Transistor 665) is a SMD component package with 5 leads. It is commonly used for TVS diodes manufacturer by NXP and STMicroelectronics.

Synonyms

  • SOT-665
  • SOT-665-5: Used by Mouser1. Presumably the 5 is added to indicate the number of leads.

Dimensions

Below are the dimensions for the SOT-665 component package from NXP2:
