Product Summary

The NTE5452 through NTE5458 are sensitive gate, 4-amp silicon-controlled rectifiers in TO202 type packages which are designed to be driven directly with IC and MOS devices. These reverse−blocking triode thyristors may be switched from off−state to conduction by a current pulse applied to the gate terminal. They are designed for control applications in lighting, heating, cooling, and static-switching relays.

  • IGT = 200uA
  • Repetitive peak reverse voltage (Tc = +100°C): 400V
  • Repetitive peak off--state voltage (Tc = +100°C): 400V
  • RMS on--state current: 4A
  • Peak surge (nonrepetitive) on−state current (one cycle at 50 or 60Hz): 20A
  • Peak gate-trigger current: 1A
  • Average gate power dissipation: 200mW
  • Operating temperature range: -40°C to 100°C
  • Storage temperature range: -40° to 150°C
  • Thermal resistance, junction--to--case: 5°C/W
