Diodes – Rectifiers – Single is a broad range of rectifier diodes that are used in the production and manufacture of a variety of electronic components. The SR815HR0G is one such an example that is used particularly in the fields of locomotive and ship propulsion systems.

A rectifier diode has the capability to convert alternating current (AC) input into direct current (DC) output. The SR815HR0G is a reverse-blocking device designed to work effectively as a standard electrical rectifier, and it can handle power up to 200V and 800A of peak current. This makes it an ideal choice for high voltage tractive power applications, such as the ones commonly found on locomotives and ships.

The diode has a maximum forward voltage drop of 1.15V and it reaches a temperature of -55 °C to +125 °C. It is designed to work using a three-terminal package, including an anode, a cathode, and an auxillary terminal. It is capable of handling power of up to 200V and a peak current of 800A, making it an ideal choice for such applications as traction power supplies in ships and locomotives.

The working principle of the SR815HR0G is based on the principle of minority carrier injection. Under this principle, when an electrical current is applied to the diode, the charge carriers inside the diode become polarized and asymmetrically distribute themselves. This creates a voltage potential between the anode and cathode of the diode, which then serves as the rectifying function of the rectifier diode, allowing for the conversion of AC input into DC output.

Since the SR815HR0G is designed for high voltage tractive power application, it also features an additional auxillary terminal, which is designed to provide a higher current rating than the anode or cathode, allowing for larger currents to flow through the diode when needed. This makes it suitable for applications where very large currents are needed.

In summary, the SR815HR0G is an ideal choice for high voltage tractive power application in locomotives and ships due to its capability of handling high voltages and 800A peak currents. It is based on the principle of minority carrier injection and features an auxillary terminal to provide a higher current rating. It has a maximum forward voltage drop of 1.15V and an operating temperature range of -55 °C to +125 °C.
