G00378   NMAH Catalog Number 1987.0487.072
 
TI number: G00378
Wafer, Transient Suppressor Thyristor - See G00377 for description of the transient suppressor thyristor. This slice was fabricated in 1981 in the initial development efforts. It completed all of the normal front end operations.

Related material in collection: G00377, 9, PG00093. Summary comment by: Mick Maytum, Dave Storey, Phil Tizzard.

G00379   NMAH Catalog Number 1987.0487.073
 
TI number: G00379
Wafer, Transient Suppressor Thyristor - This slice contains bars for the transient suppressor device described under G00377 which have been processed beyond the slice under G00378. The pattern of alloy solder balls has been applied to make the contracts with the package lead.

This slice was fabricated in 1981 during the initial development efforts.

G00365   NMAH Catalog Number 1987.0487.094
 
TI number: G00365
Thyristor - This device is a TI plastic encapsulated silicon thyristor intended for industrial and consumer applications. The mounting flange provided a heat dissipation path.

The packaging was designed for low cost mechanized assembly. The device series ratings were 600mAdc and up to 200Vdc. The code "A638A" indicates USA fabrication in 1976, 38th week and lot A for that week. TI halted production of this device line about 1980.

G00374   NMAH Catalog Number 1987.0487.114.01
 
TI number: G00374
Thyristors - Fluoractor is the name given by TIL to a Darlington connected pair of thyristors in a JEDEC T0-220 plastic package. This device is a new form of fluorescent tube starter developed by TIL working a UK starter manufacturer.

This is an excellent example of a new product developed for a mature market. Development started July 1, 1981, with first samples in August, 1982. These units are from the prototypes which were built until February, 1983. Production began in 3Q83, with 2M units produced through March, 1986. See the Artifact Historical File for additional information.

Related material in collection: G00375-6 (Slices), PG00092. Summary comment by: Mick Maytum, Dave Storey, Phil Tizzard.

G00377   NMAH Catalog Number 1987.0487.115.01
 
TI number: G00377
Thyristors, Transient Suppressor - The transient suppressor bar (chip) consists of multiple high holding current voltage triggered crowbars used for overvoltage protection of any electronics connected to the telephone line.

The device is a four layer diode based on vertical thyristor technology and is unusual in having "top to bottom" symmetry in various areas, requiring similar implants and diffusions on both sides of the slice. TI's ion implanted planar technology permits the integration of four close tolerance crowbars on one bar (chip). Bar size is .140" x .140". Initial work began in mid 1981, and first production volumes were in late 1983. Approximately 4M units have been shipped in the first three years of production. See Artifact Historical File for additional information.
