Frequently asked questions
What is the price of AO3401 P-Channel MOSFET 30V 4.2A SOT-23 in Egypt?
AO3401 P-Channel MOSFET 30V 4.2A SOT-23 currently costs between 3 and 3.5 EGP across 2 offers in Egypt.
Where can I buy AO3401 P-Channel MOSFET 30V 4.2A SOT-23 in Egypt?
AO3401 P-Channel MOSFET 30V 4.2A SOT-23 is available from UGE and Makers Electronics. Compare the offers above to find the best price.
How do I use the AO3401 as a high-side switch?
Connect the source to the supply and the load to the drain. Pull the gate low to turn the MOSFET on, and drive the gate to the source voltage to turn it off.
Can a 3.3 V microcontroller drive it directly?
The gate threshold is 1.3 V, but the listed on-resistance is specified at VGS = 10 V. At lower gate drive the on-resistance is higher, so check the datasheet curves before relying on full current at 3.3 V.
