Silicon Grown Junction Power Transistor
TI number: G00402

This transistor was a special device version of the TI970 and 2N122 silicon power transistor. The long leads were used for a customer whose design required this length between the heat sink mounting and the electrical connections.

See G00046 for description of the TI970 and 2N122. These leads were impractical for handling in production and testing and were subsequently replaced. Short rigid leads were made as part of the header. Following production and testing, the long flexible leads were attached by spot welding so that the final device satisfied the mounting requirements.
