1N459A_S00Z

The 1N459A_S00Z single diode rectifier is a component commonly found in a variety of applications and equipment. This device features glass construction with a reverse voltage rating of 1000 volts, a non-repetitive peak surge current of 8.0 amperes and an average forward current of 1.0 amperes.

The main function of the 1N459A_S00Z is to convert alternating current (AC) to direct current (DC), allowing for efficient operation of a variety of items. In this process, the single diode rectifier will block one side of the current flow, preventing it from ever reaching the output. This requires the two levels of voltage, known as the anode and cathode, to be of opposite polarity for the device to function properly. The application of a single diode rectifier is often seen in items such as power supplies, AC motor controllers, or low voltage lighting.

Ideally, a single diode rectifier should be deployed in a half wave configuration, which involves connecting the output to the half of the AC waveform that has the correct polarity. This leaves half the voltage potential unused and limits the current to one direction. Despite the lack of efficiency, this configuration is chosen to avoid unnecessary losses, since diode rectifiers suffer from a significant amount of power dissipation when in operation. However, a full wave rectifier arrangement can be implemented to take advantage of the full voltage potential, although this comes with added complexity and cost.

In addition to converting AC to DC power, the single diode rectifier is also useful for controlling surges. By implementing an external diode before the input, the rectifier can be used to limit excess voltage entering the circuit. The diode will conduct the current until the supply voltage drops below the diodes minimum forward voltage, at which point the diode will deactivate, leaving the circuit unharmed.

The desired application for a 1N459A_S00Z will depend on contamination, rise time and capacitance as well as the availability of low voltage components. Most of these considerations relate to the amount of power the device is able to handle and the type of circuit it is connected to. A thorough investigation of the aforementioned variables is advised before making any purchasing decisions.
