1200 V power Schottky silicon carbide diode
  • active Active

ST's 1200 V high-performance rectifier is specifically designed to be used in photo-voltaic inverters or in applications where negligible switching losses are required.

The STPSC6H12 helps to increase the application efficiency yield by up to 2% thanks to its ability to work at high frequency whatever the temperature.

The central lead of the DPAK package is removed to meet the IEC60664 and UL 840 standards requirements for a higher voltage.

These characteristics make it the best-in-class 1200 V diode.
