Frequently asked questions
What is the price of IRF643 N-Channel Power MOSFET 150V 16A TO-220AB in Egypt?
IRF643 N-Channel Power MOSFET 150V 16A TO-220AB currently costs 20 EGP in Egypt.
Where can I buy IRF643 N-Channel Power MOSFET 150V 16A TO-220AB in Egypt?
IRF643 N-Channel Power MOSFET 150V 16A TO-220AB is available from Makers Electronics. Compare the offers above to find the best price.
How do I drive the gate of the IRF643 from a microcontroller?
The gate is voltage-controlled. A standard IRF643 needs a gate voltage around 10V for full enhancement, so a 5V microcontroller pin usually needs a gate driver or level-shifting stage. Add a gate resistor and a pull-down resistor to keep the device off during startup.
Does the IRF643 need a heatsink?
At high load current, yes. The TO-220AB package should be mounted on a heatsink, and the power dissipation should be calculated from the on-resistance and current in your circuit.
