Frequently Asked Questions
1.What is 1N5818?
The 1N5817, 1N5818, and 1N5819 are a family of low-drop 1 A Schottky rectifier diodes. The 1N5818 is known as a hot-carrier diode that is employed for extremely fast switching applications. Packaged in DO-41, the 1N5818 is intended for use in low voltage, high-frequency inverters, freewheeling, polarity protection, and small battery chargers.
2.What is the difference between diode and Schottky diode?
One of the primary advantages of using a Schottky diode over a regular diode is its low forward voltage drop. This allows a Schottky diode to consume less voltage than a standard diode, using only 0.3-0.4V across its junctions. The conventional diode consumes 0.7V, leaving only 1.3V to power the load.
3.Can I replace a diode with any diode?
Diodes can always be replaced with those of higher capacity since a component with greater current capacity can always handle the lower current. One needs to check its PIV, and sometimes the forward voltage drop. A transistor can be replaced by a larger one, provided its characteristics are permissible for the circuit.
4.Can I replace 1N5818 with 1N5819?
Yes, you can replace 1N5818 with 1N5819. They are from the same series and the only difference is that 1N5819 has a higher reverse voltage.
