TDS4__4402
Phase Control Thyristor
Powerex, Inc., 173 Pavilion Ln, Youngwood, PA 15697 www.pwrx.com (724)925-7272
4400Amperes 2400Volts
The TDS4 is a medium voltage, high current,
thin pack disc SCR employing a amplifing
gate structure. This thin package provides
greater cooling thus maximizing high current
performance. The amplifing gate design
allows the SCR to be reliably operated at high
di/dt and dv/dt conditions in various phase
control applications.
