Product details

The STP200NF03: The gate charge is 140 nC at 10 V, so the gate driver needs to source enough peak current to switch the 4950 pF input capacitance cleanly at your target frequency.

That means STMicroelectronics is not actively promoting this part for new projects, and it may be moved to end-of-life without a long last-time-buy window.

Through-hole TO-220 — hand-solderable and board-mount practicalities

The STP200NF03 comes in a through-hole TO-220-3 package (supplier device package TO-220). You can hand-solder it onto a perfboard or a PCB with a standard soldering iron; the 300 W maximum power dissipation assumes the tab is bolted to a heatsink with good thermal interface material.

Frequently asked questions

Is STP200NF03 obsolete? Will it be discontinued?

STMicroelectronics may issue a last-time-buy notice in the future. For new designs, choose a current-production alternative.

What is the Rds(on) of STP200NF03?

This is the on-resistance figure you use for conduction loss calculations in a switching power supply or load switch.
