Planar passivated Silicon Controlled Rectifier with sensitive gate in a SOT54 (TO-92) plastic package. This SCR is designed to be interfaced directly to microcontrollers, logic ICs and other low power gate trigger circuits.

Features and Benefits
  • Guaranteed minimum gate trigger current limit
  • Planar passivated for voltage ruggedness and reliability
  • Sensitive gate
  • Direct triggering from low power gate circuits and logic ICs
  • Ground Fault Interrupters (GFI)
  • Leakage Current Circuit Breakers (LCCB)
  • Residual Current Devices (RCD)
