Frequently asked questions
What is the price of 2N3819 N-Channel JFET TO-92 Transistor in Egypt?
2N3819 N-Channel JFET TO-92 Transistor currently costs 18 EGP in Egypt.
Where can I buy 2N3819 N-Channel JFET TO-92 Transistor in Egypt?
2N3819 N-Channel JFET TO-92 Transistor is available from Circuits Electronics. Compare the offers above to find the best price.
How do I use it as a switch?
It is normally on when VGS is 0 V, so applying a negative gate-source voltage beyond the cutoff value turns it off. Check the datasheet pinout for your package, since pin order varies by manufacturer.
What gate voltage conditions should I avoid?
Keep the gate-source junction reverse-biased during normal operation. Forward-biasing the gate can damage the device.
