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.
