300 V, 50 A — StrongIRFET™ in a TO-247-3
The IRF300P227: It comes in a through-hole TO-247-3 package (PG-TO247-3), which means you can swap it on site with a screwdriver and a soldering iron — no hot-air station, no reflow profile.
40 mOhm Rds(on) — conduction loss at 30 A
The on-resistance is 40 mOhm maximum at 30 A drain current with 10 V gate drive. The 313 W power dissipation rating supports pulsed operation.
107 nC gate charge — drive current budget
Gate charge is 107 nC at 10 V. The input capacitance is 4893 pF at 50 V drain-source.
Not a logic-level FET — needs 10 V drive
The gate threshold voltage is 4 V maximum at 270 µA drain current. The specified drive voltage for minimum Rds(on) is 10 V, and the absolute maximum gate-source rating is ±20 V.
The junction temperature range is -55°C to 175°C.
