It's a NPT Trench IGBT. "NPT" means non-punch-through, and it refers to how the silicon is configured. Same goes for "trench".

SOA = safe operating area = a graphical representation of the maximum operational voltage and current limits (i-v) of the device subjected to various constraints.

Tips

• put a diode across the outputs, to protect the IGBT from back-EMF
• Use diodes and TVSs (transient voltage suppressors)

IGBT circuits

• TV flyback driver

Tip of the iceberg

• this discussion here says that he used a circuit somewhat like this? (he posts the circuit later, but the URL has since died)
