The 1N4448,143 diode consists of a metal-semiconductor junction. In the forward bias condition, this junction acts as a rectifier, allowing to carry current in one direction, while blocking or preventing current in the opposite direction. The forward voltage drop is the voltage which appears across the diode when passing a given current in the forward direction. The reverse leakage current, or leakage current, is the amount of current which flows through the junction in the reverse bias condition.

In conclusion, the 1N4448,143 diode is a low-power, high-current Schottky diode. It is widely used in automotive electronics, portable electronics and electronic accessories. It has a low forward voltage drop, low reverse leakage current and low reverse recovery time, making it ideal for fast switching applications.
