Listed below are various model files I've collected from the web over the last year:

IGBTs

• nigbt.sub - N channel IGBTs
• pigbt.sub - P channel IGBTs

MOSFETs

• ndmos3t.mod - N channel MOSFETs
• nemos3t.mod - N channel MOSFETs
• nemossu3.sub - N channel MOSFET subcircuits
• nmos.mod - N channel MOSFETs

• pemos3t.mod - P channel MOSFETs
• pemossu3.sub - P channel MOSFET subcircuits
• pmos.mod - P channel MOSFETs
