Maximum gate-source voltage is ±30 V. ## NRND — plan a last-time buy or alternate For a production BOM that already qualifies this MOSFET, the last-time-buy window may be open. For new designs, a pin-compatible SuperMESH replacement with similar voltage and current class should be evaluated.","metaTitle":"STP5NK52ZD N-Channel MOSFET, 520V 4.4A TO-220, SuperMESH","metaDescription":"STP5NK52ZD N-channel MOSFET, 520 Vdss, 4.4 A Id, 1.5 Ω Rds(on) at 10 V.
