* Optional TM lead consist of 20AWG FEP insulated twisted pair wires 17.5 inches in
length with ¼" insulated fast-on terminals.
The TCU4 is a high voltage, high current
disc pack SCR employing a high di/dt
gate structure. This gate design allows
the SCR to be reliably operated at high
di/dt and dv/dt conditions in various
phase control applications.
