Product details

60 V, 24 A N-channel in a TO-3 can

The IRF143 is a 60 V, 24 A N-channel power MOSFET in a through-hole TO-3 package.

Gate drive and switching budget

The gate-source voltage is rated to ±20 V, giving headroom for standard 10 V or 12 V gate drive without clamping. With a total gate charge of 60 nC at 10 V, the driver must supply about 60 mA per MHz of switching frequency — a typical 100 kHz hard-switched stage draws roughly 6 mA from the driver, well within a standard gate-drive IC's capability.

Thermal and environment rating

The 125 W power dissipation rating assumes the TO-3 case is bolted to an adequate heatsink — the metal tab is the primary thermal path.

Frequently asked questions

What is the IRF143 datasheet and where can I find it?

Design engineers need full specs (Rds(on), Qg, etc.) to validate the part in their circuit.

Is IRF143 obsolete or active?

Buyers and brokers need to confirm lifecycle to avoid risking a BOM line with an EOL part.

What is the IRF143 replacement or equivalent?

Sourcing buyers need substitutes if the exact part is unavailable or price-spiked.

Where can I buy IRF143 and what is the price?

Transactional intent – buyers need a purchasing link and real-time pricing to fulfill the BOM.

What is the pinout and package of IRF143?

Maintenance techs replacing a failed part need to know pin compatibility with the existing socket (TO3).

What is the IRF143 cross reference?

Cross-reference helps brokers quickly check if another manufacturer's part is a drop-in replacement.
