IRF630 — 200V 9A N-Channel MOSFET in TO-220
It comes in a standard TO-220-3 through-hole package, making it a common choice for offline power supplies, DC-DC converters, and motor-drive output stages where the voltage and current fit within a 150 W dissipation envelope. The 10 V drive requirement means this is not a logic-level MOSFET — it expects a gate driver that can swing to 10 V for the lowest Rds(on). These numbers define the switching speed and the gate-drive power budget.
Where it fits — application and environment
The TO-220 package bolts to a heatsink with a single screw — common in open-frame power supplies and motor-drive heatsinks.
