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
□Shor t Turn-on Time – Suitable
to Pulse Use
Applications:
□Phase Control
□Triggering of High Power
Thyr istors, Pulse Generators
and Counters
□Static Switch
□Motor Control
□Strobe Flasher
Ordering Information:
Example: Select the complete
seven or eight digit par t number
you desire from the table - i.e.
CR04AM-8 is a 400 Volt, 0.4
Ampere Phase Control SCR.
