STMicroelectronics lists the STF4NK50ZD as Obsolete. The base product number is STF4N, which may help identify functionally similar devices in the same family, but pin-compatibility and parametric match must be verified per design.
Yes, STMicroelectronics has marked the STF4NK50ZD as Obsolete. No direct replacement or successor part number has been issued by the manufacturer.
There is no official equivalent from STMicroelectronics. The base product number STF4N covers the family, but any substitute must be evaluated for 500 V drain-source, 3 A continuous current, 2.7 Ω Rds(on), and the TO-220 Full Pack package.
