Phase Control Thyristo
Powerex, Inc., 200 Hillis Street, Youngwood, Pennsylvania 15697-1800 (724)925-7272 3300 Amperes 4500 Volts
The TDK4 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.
FEATURES:
Low On-State Voltage
High di/dt Capability
High dv/dt Capability
Hermetic Ceramic Package
Excellent Surge and I
APPLICATIONS:
DC Power Supplies
ORDERING INFORMATION Motor Controls
Select the complete 12 digit Part Number using the table below.
EXAMPLE: TDK4443302DH is a 4400V-3300A SCR with 300ma
IGT and 12 inch gate and cathode potential leads.
