The TAK7 is High Voltage version of the PRX
TA20 medium voltage, high current disc pack
SCR. It employs a Single-Bar gate,
amplifying gate structure. This amplifying
gate design allows the SCR to be reliably
operated at high di/dt and high dv/dt
conditions in phase control applications.
FEATURES:
Low On-State Voltage
High di/dt Capability
High dv/dt Capability
Hermetic Ceramic Package
Excellent Surge and I
