80 A High Temperature Thyristor (SCR)

Available in high power package (D3PAK), the device is suitable in applications where power switching (IT(RMS) = 80 A at TC = 130 °C) and power dissipation (VTM = 1.55 V at 160 A) are critical, such as motorbike voltage regulator, by-pass AC switch, controlled rectifier bridge, solid state relay, battery charger, welding equipment and motor driver applications. The TM8050H-8D3 is available in surface mount D3PAK package.

Key Features

  • High junction temperature: Tj = 150 °C
  • Blocking voltage: VDRM = VRRM = 800 V
  • Nominal current: IT(RMS) = 80 A
  • Gate triggering current: IGT max. = 50 mA
  • High noise immunity: dV/dt > 1 kV/µs
  • Surface mounted device D3 PAK
  • Increase of thermal margin due to extended Tj up to 150 °C
  • Low ID and IR in blocking state
  • High compact power SMD design
