STMicroelectronics lists the STP5NK50ZFP as NRND (Not Recommended for New Design). No last-time-buy date is published in the current record. For an existing production BOM, the NRND status means you have time to qualify a replacement, but you should not start a new design with this order code. The TO-220FP package dissipates up to 70 W at the case, but the isolated tab means the thermal resistance from junction to case is higher than a standard TO-220 — account for that when sizing the heatsink at high ambient temperatures.","metaTitle":"STP5NK50ZFP N-Channel MOSFET, 500V, 1.5 Ohm, TO-220FP","metaDescription":"STMicroelectronics STP5NK50ZFP SuperMESH N-channel MOSFET: 500V Vdss, 4.4A Id, 1.5 Ohm Rds(on), TO-220FP isolated package.
