Description:
The Powerex CR04AM Lead
Mounted, Phase Control SCRs are
glass-passivated thyristors for use
in low power control and rectifica-
tion. These devices are molded sil-
icone plastic types.
Features:
Glass Passivation
Short Turn-on Time Suitable
to Pulse Use
Applications:
Phase Control
Triggering of High Power
Thyristors, Pulse Generators
and Counters
Static Switch
Motor Control
Strobe Flasher
Ordering Information:
Example: Select the complete
seven or eight digit part number
you desire from the table - i.e.
CR04AM-8 is a 400 Volt, 0.4
Ampere Phase Control SCR.
