thin small outline transistor (package) (TSOT)
The Thin Small Outline Transistor (TSOT) is a small transistor package with 6 pins. TSOT packages have dimensions in the millimeter range. For example, the TSOT transistor package has dimensions of 1.65 mm wide, 2.97 mm long and 0.87 mm thick. The spacing of the terminals is 0.95 mm.
The TSOT package is designed for SMT technology and can also contain analog electronic circuits for voltage regulation or AD conversion. Corresponding packages are slightly larger and have 8 pins.
