PRX C770__ Fast Switching Thyristor Powerex, Inc., 173 Pavilion Lane, Youngwood, PA 15697-1800 724-925-7272 WWW.PWRX.COM 2100 Amperes 2000 Volts FEATURES: Fast Turn-Off Time High di/dt Capability High dv/dt Capability Hermetic Ceramic Package Excellent Surge and I2t Ratings APPLICATIONS: DC-AC Inverters ORDERING INFORMATION Pulse Power Switches Select the complete Part Number using the table below. EXAMPLE: PRX C770PN is a 1800V - 2100A SCR with 250ma IGT and 12 inch gate and cathode potential leads. PART Voltage Rating Voltage Code Current Rating Turn-Off Gate Leads VDRM-VRRM Itavg Tq IGT PRX C770__ 2000 L 2100 60us 250ma 12" 1800 PN 1600 PM 1400 PD Revised: 7/24/2012 The PRX C770 is a high voltage, high current disc pack SCR employing a high di/dt, distributed gate structure to optimize turn-on speed. This gate design allows the SCR to be reliably operated at high di/dt and dv/dt conditions in inverter applications to 1KHz operating frequency. Page 1 of 4
