Diodes are semiconductors used within various electronics systems. A diode is a semiconductor device that allows electrical current to flow in only one direction. Rectifiers are diode components that only allow current to flow in one direction—they are utilized to convert alternating current (AC) to direct current (DC). Rectifier arrays are similar, but with multiple diodes connected in series, parallel, or combinations of both. A popular example of rectifier arrays is the SB80W10T-H. This type of rectifier array has two main applications and relies on two different principles for operation. First, the SB80W10T-H may be used as a converter, either converting AC to DC, or a higher voltage DC to a lower voltage DC due to series, parallel, and combination configurations of the rectifiers. As an example, the rectifiers may be used within a converter to convert 110v AC to 12v DC. In this application, the SB80W10T-H harnesses the process of electrorectification, which is the deformation of an electrical field when an alternating voltage is applied. The second application for the SB80W10T-H is as reverse polarity protection. This requires placing the rectifiers in a combination configuration with an additional diode. This allows for current to only flow in one direction, protecting the device it is placed in from damage due to reverse voltage or polarity. In this configuration, the rectifiers take advantage of the Shottky diode effect, which is the “reverse electric field” effect integrated within the diode. Regardless of the application, the one key factor to consider with the SB80W10T-H rectifier array is that it can deliver current up to 10A. If more current is needed, then a different type of rectifier array must be chosen. The SB80W10T-H operates within the temperature range of -55°C to +125°C, so proper cooling measures should be implemented as needed. The standard peak forward voltage per element is typically 1.15V, with an acceptable variation of 1.00V to 1.25V. Finally, the mounting requirements for the SB80W10T-H must be considered, as the rectifier array is most typically solderedwithin printed circuit boards (PCBs).
