Frequently asked questions
What is the price of IRF820 N-Channel Power MOSFET 500V 2.5A TO-220 in Egypt?
IRF820 N-Channel Power MOSFET 500V 2.5A TO-220 currently costs 19.9 EGP in Egypt.
Where can I buy IRF820 N-Channel Power MOSFET 500V 2.5A TO-220 in Egypt?
IRF820 N-Channel Power MOSFET 500V 2.5A TO-220 is available from Most Electronics. Compare the offers above to find the best price.
Can I drive the IRF820 directly from a 5V Arduino pin?
Not reliably. Its gate threshold is 2 V to 4 V and it reaches full enhancement at about 10 V gate drive, so 5 V logic may leave RDS(on) high and cause heating. Use a logic-level MOSFET or a gate driver, with a series gate resistor.
What is the pin order of the IRF820?
In the standard TO-220 orientation, with the metal tab facing away from you and the pins pointing down, the pins are Gate, Drain and Source from left to right. Confirm this against the datasheet before wiring.
