SAFEIR Series
40TTS12PbF
Description/ Features
The 40TTS12PbF SAFEIR series of silicon con-
trolled rectifiers are specifically designed for me-
dium power switching and phase control applica-
tions. The glass passivation technology used has
reliable operation up to 140°C junction tempera-
ture.
Typical applications are in input rectification (soft
start) and these products are designed to be used
with International Rectifier input diodes, switchewwsw.DataSheet4U.com
and output rectifiers which are available in identical
package outlines.
