The US Navy issued the first Military Procurement Specification covering silicon transistors for these type numbers. TI was the first qualified supplier. Production of silicon transistors in this package continued into 1973. (Series shown in 1973 Data Book.) The design work for the welded package was done on a Signal Corps Manufacturing Methods contract.
