Semiconductor device

A semiconductor device comprising:

• a switching element having an element obverse surface and an element reverse surface that face away from each other in a first direction, and including a drain electrode, a gate electrode, and a source electrode, the switching element performing on/off control between the drain electrode and the source electrode by applying a driving voltage across the gate electrode and the source electrode with a potential difference being present between the drain electrode and the source electrode;
• a base having an obverse surface and a reverse surface that face away from each other in the first direction, and supporting the switching element with the element reverse surface facing the obverse surface;
• and
• a first terminal, a second terminal, a third terminal, and a fourth terminal that each extend in a second direction perpendicular to the first direction,
• wherein the switching element includes a temperature detection diode having a first electrode provided on the element obverse surface,
• each of the drain electrode, the gate electrode, and the source electrode is electrically connected to a corresponding one of the first terminal, the second terminal, and the third terminal, and
• the first electrode is electrically connected to the fourth terminal via a first wire.
