Planar passivated Silicon Controlled Rectifier in a SOT1292(IITO3P) plastic package intended for use in applications requiring very high inrush current capability and high thermal cycling performance. It is used in applications where "high junction operating temperature capability" (Tj(max) = 150 °C) is required.

Features and Benefits
  • High thermal cycling performance
  • Planar passivated for voltage ruggedness and reliability
  • High voltage capacity
  • Very high current surge capability
  • High junction operating temperature capability (Tj(max) = 150 °C)
  • Line rectifying 50/60 Hz
  • Softstart AC motor control
  • DC Motor control
  • Power converter
  • AC power control
  • Lighting and temperature control
  • Uninterruptible Power Supply (UPS)
  • Solid State Relay (SSR)
  • Traction battery charging
  • Applications subject to high temperature (Tj(max) = 150 °C)
