Abstract

スイッチング装置としての複合半導体装置（２０）は、第１及び第２の主端子（１１，１２）と、主制御端子（１３）と、主IGFET（１４）と、保護スイッチング素子としての副IGFET（１５）と、ゲート抵抗（１６）とを有する。主IGFET（１４）は第１及び第２の主端子（１１，１２）間に接続されている。副IGFET（１５）は主IGFET（１４）のドレイン電極（Ｄ１）とゲート電極（Ｇ１）との間に接続されている。副IGFET（１５）のゲート電極（Ｇ２）は主IGFET（１４）のソース電極（Ｓ１）に接続されている。副IGFET（１５）は主IGFET（１４）に逆方向電圧が印加された時にオンになる。これにより主スイッチング素子としての主IGFET（１４）の保護が達成される。
