TSOT Package (Thin Small Outline Transister)
SOT23 Package (Standard Outline Transistor)

SOT23 and TSOT are leadframe based, plastic encapsulated packages that are well suited for applications requiring very small footprints. These industry standard packages run in very high volume and provide cost effective solutions for a wide range of applications. Having up to 8 leads, these packages can handle small ICs that may have previously been packaged in SOIC or TSSOP. A green BOM is standard, allowing devices to meet applicable Pb free and RoHS standards.
