★ ★ ★ ★ ☆

Forward blocking capability of double gate IGBTs (DG-IGBT) at high temperature was analysed using numerical simulations. It was found that the DG-IGBT behaves like a DMOS transistor at 200°C with much lower leakage current compared with that of a conventional IGBT.

SCRs are available with reverse blocking capability, which adds to the forward voltage drop because of the need to have a long, low-doped P1 region. (If one cannot determine which region is P1, a labeled diagram of layers and junctions can help.) Usually, the reverse blocking voltage rating and forward blocking voltage rating are the same.
