ツール & ソフトウェア

STのSiC(シリコン・カーバイド)ダイオードは、今日の厳しい省エネ規制(Energy Star / 80Plus / European Efficiency)に適合し、標準的なシリコン・ダイオードと比べて15%低い順電圧降下(VF)で4倍優れた動的特性を実現しています。 



STは、600V~1200V定格でダイオード1素子入りおよび2素子入りの構成を、PowerFLATTM 8 x 8からTO-247までのさまざまなパッケージ・サイズで提供しています。セラミックで絶縁されたTO-220パッケージも用意されています。10A、15Aおよび20AバージョンのSiCダイオードは、沿面距離が長いD2PAKパッケージで新たに提供され、より高い電気規格と汚染規格に対応しています。



SiC diodes – compact surface-mount PowerFLAT™ 8x8 HV packages

To help engineers design denser, more efficient power conversion stages, ST's compact surface-mount PowerFLAT™ 8x8 HV devices feature excellent thermal performance. Moreover, ST took a few extra steps to propose a 4 to 10 A range (STPSC4H065DLFSTPSC6H065DLFSTPSC8H065DLF, STPSC10H065DLF and STPSC10065DLF) with super-power density.

  • Package less than 1 mm thick
  • Forward voltage (VF) improved by 200 mV
  • High-voltage creepage: 2.75 mm
  • Designed and built for high inrush current (IFSM)
  • Rth thermal resistance as low as 1.7°C/W
