A Touchstone file (also known as an SnP file after its set of file extensions [3]) is an ASCII text file used for documenting the n-port network parameter data and noise data of linear active devices, passive filters, passive devices, or interconnect networks. An example of the format of the S-parameter section is given in the article about S ...
SOT: Small-outline transistor (also SOT-23, SOT-223, SOT-323). TO-XX: wide range of small pin count packages often used for discrete parts like transistors or diodes. TO-3: Panel-mount with leads; TO-5: Metal can package with radial leads; TO-18: Metal can package with radial leads; TO-39; TO-46; TO-66: Similar shape to the TO-3 but smaller
Several variants of the original TO-5 package have the same cap dimensions but differ in the number and length of the leads (wires). Somewhat incorrectly, TO-5 and TO-39 are often used in manufacturer's literature as synonyms for any package with the cap dimensions of TO-5, regardless of the number of leads, or even for any package with the diameter of TO-5, regardless of the cap height and ...
Listed are many semiconductor scale examples for various metal–oxide–semiconductor field-effect transistor (MOSFET, or MOS transistor) semiconductor manufacturing process nodes. Timeline of MOSFET demonstrations
The "TO" designation stands for "transistor outline". [2] TO-220 packages have three leads. Similar packages with two, four, five or seven leads are also manufactured. A notable characteristic is a metal tab with a hole, used to mount the case to a heatsink, [3] allowing the component to dissipate more heat than one constructed in a TO-92 case.

In electronics, TO-3 is a designation for a standardized metal semiconductor package used for power semiconductors, including transistors, silicon controlled rectifiers, and, integrated circuits.

SPEF is the most popular specification for parasitic exchange between different tools of electronic design automation (EDA) domain during any phase of design. The specification for SPEF is a part of the 1481-1999 IEEE Standard for Integrated Circuit (IC) Delay and Power Calculation System.
