700 V N-channel in a fully isolated TO-220 — the repair-bench view
The IPAN70R360P7SXKSA1: This is the part you reach for when a board-level repair calls for a through-hole replacement in an offline flyback supply, a PFC boost stage, or a 400 V DC-link auxiliary converter — the isolated tab saves you the mica washer and thermal grease, and the 150 °C junction rating means it survives the hot corner of a sealed PSU.
The 26.5 W package limit (Tc) constrains continuous drain current; practical operation requires adequate heatsinking.
Infineon lists the IPAN70R360P7SXKSA1 as Active. If you are retrofitting a board that originally used an older CoolMOS generation, check the gate-drive voltage — the P7 series is optimized for 10 V drive.
