| Preliminary Data Sheet I2144 11/97 SAFEIR Series 12TTS08 PHASE CONTROL SCR VT Description/Features The 12TTS08 SAFEIR series of silicon controlled rectifiers are specifically designed for medium power switching and phase control applications. The glass passivation technology used has reliable operation up to 125 C junction temperature. Typical applications are in input rectification and crow-bar (soft start) and these products are designed to be used with International Rectifier input diodes, switches and output rectifiers which are available in identical package outlines. < 1.2V @ 8A ITSM = 140A VRRM = 800V Output Current in Typical Applications Applications Capacitive input filter TA = 55C, TJ = 125C, common heatsink of 1C/W Single-phase Bridge 13.5 Three-phase Bridge Units 17 A Major Ratings and Characteristics Characteristics IT(AV) Sinusoidal waveform IT(RMS) VRRM/VDRM ITSM VT dv/dt di/dt TJ range @ 8 A, TJ = 25C 12.5 800 140 1.2 150 100 - 40 to 125 A V A V V/s A/s C Package Outline Units A 12TTS08 8 TO-220AC Also available in SMD-220 package (series 12TTS..S) 1 12TTS08 SAFEIR Series Preliminary Data Sheet I2144 11/97 Voltage Ratings Part Number 12TTS08 VRRM, maximum peak reverse voltage V 800 VDRM , maximum peak direct voltage V 800 IRRM/IDRM 125C mA 1.0 Absolute Maximum Ratings Parameters IT(AV) Max.
