The through-hole TO-251-3 (IPak) package suits compact board layouts where a heatsink tab is soldered to the PCB copper.
The 3.9 V maximum gate threshold at 250 µA means a 5 V logic gate drive may not fully enhance the channel; the datasheet recommends 10 V drive for the rated Rds(on).
No end-of-life notice or last-time-buy schedule is in effect. For dual-sourcing or supply resilience, Infineon's CoolMOS portfolio includes several 600 V N-channel parts in the same TO-251 package; the closest functional match would share the same Vdss and current class, but no official cross-reference is listed in the evidence.
