11. Schottky diodes are commonly used in Dickson multipliers for their low forward voltage drop, amongst other reasons. 12. Typically, the forward voltage of an LED is between 1.8 to 3.3 volts. 13. During turn off, the forward voltage of the device must be limited until the current tails off. 14. The voltage across the inductor will merely be a function of the forward voltage drop of the flyback diode. 15. When an electrical forward voltage is applied an injection current across the active region of the SLED is generated. 16. However, during the forward half-cycle the voltage will be limited by the forward voltage of the diode. 17. Devices such as diodes conduct when a forward voltage is applied and have no external control of the start of conduction. 18. In summary, current injection technique makes it possible to use devices with low forward voltage drop for high frequency applications. 19. While higher reverse voltages are achievable, they would present a higher forward voltage , comparable to other types of standard diodes. 20. Typically the specification will primarily provide a maximum forward voltage drop at one or more forward currents and a reverse leakage current.
