ST lists the STP5N52K3 as obsolete. For BOM lines that still call out this exact code, procurement goes through independent distribution channels — surplus stock, last-time-buy inventory, or broker-sourced new-old-stock. Input capacitance measures 450 pF at 100 V drain-source, giving a reasonable Ciss figure for the voltage class. The 4.5 V gate threshold maximum at 50 µA drain current means the device needs a full 10 V gate drive to achieve the rated on-resistance — logic-level drive at 5 V will not fully enhance the channel. The ±30 V maximum gate-source rating gives good noise margin on the gate drive line.","metaTitle":"STP5N52K3 N-Channel MOSFET, 525 V, 4.4 A, TO-220","metaDescription":"STP5N52K3 SuperMESH3 N-channel MOSFET, 525 Vdss, 4.4 A, 1.5 Ohm Rds(on), TO-220.

For a pin-compatible alternative in the same voltage and current class, look at other SuperMESH3 N-channel MOSFETs in TO-220 with 525 V or higher Vdss and similar Rds(on) — the STP5N52K3's base product number is STP5N, so parts sharing that prefix share the same package and pinout.
