The TO-220-3 through-hole package makes it a straightforward fit for a bolted-down TO-220 heatsink on a single-sided PCB. STMicroelectronics lists the STP7N52K3 as obsolete. A 10 V gate-drive rail is expected — the Rds(on) is specified at that voltage, and the threshold voltage max is 4.5 V at 50 µA. The ±30 V maximum gate-source rating leaves plenty of margin for ringing on a well-laid-out gate loop.","metaTitle":"STP7N52K3 N-Channel MOSFET, 525 V, 6 A, TO-220-3","metaDescription":"STP7N52K3 N-channel MOSFET, 525 Vds, 6 A, 980 mΩ Rds(on), TO-220-3.
