High Temperature 1200V 10A SiC Power MOSFET

NEPTUNE-1210 is a high-temperature, high-voltage, Silicon Carbide (SiC) MOSFET switch. It is available in a metal TO-257 package – the metal case being isolated from the switch terminals. The product is guaranteed for normal operation on the full range -55°C to +225°C. The device has a breakdown voltage in excess of 1200V and is capable of switching currents up to 10A at the maximum temperature (225°C). The device features a body diode that can be used as free-wheeling diode.

This new version D (PLA8543D), replacing obsolete version C (PLA8543C), offers lower On Resistance with equivalent switching energies.

Typical performances:

  • Temperature range: -55°C to +225°C
  • Drain voltage up to 1200V
  • Max drain current @ 225°C: 10A DC
  • RDSon= 40mΩ @ 25°C and 120mΩ @ 225°C 
  • Vgs=-4V to +20V
  • Metal TO-257 package
  • Pins electrically isolated from the case of the package


  • High Temperature, High Power Density and Extended Lifetime Power Converters
  • DC-AC Converters for Actuators and Motor Control
  • DC-DC converters
  • AC-DC converters and battery chargers
