Phase Control SCR, 12.5 A
12TTS08PbF High Voltage Series
Vishay High Power Products
DESCRIPTION/FEATURES
The 12TTS08PbF High Voltage Series of silicon
controlled rectifiers are specifically designed for
medium power switching and phase control
applications. The glass passivation technology
used has reliable operation up to 125 °C junction
temperature.
Typical applications are in input rectification and crowbar
(soft start) and these products are designed to be used with
Vishay HPP input diodes, switches and output rectifiers
which are available in identical package outlines.
This product has been designed and qualified for industrial
level and lead (Pb)-free.
