IRKD91/10A

IRKD91/10A diodes are mainly used in rectifier applications. These rectifier diodes are part of an array of rectifier components typically used in power supplies, or for other AC or DC applications. The rectifier diodes are used as a bridge rectifier on the output side of power supplies, as well as bridge rectifier used in DC-DC converters, automotive applications, and in circuit converters.

The IRKD91/10A diode comes with a nominal current rating of 1A and an optimum operating temperature range of -55 to +175°C. It is a 250V fast-recovery rectifier featuring low reverse recovery time. It has an average forward voltage of 1.1V, and the maximum repetitive peak reverse voltage is 250V. Its high reverse surge rating makes it ideal for a variety of applications.

The operating principle of the IRKD91/10A is based on a bidirectional forward-biased structure. In this arrangement, two diodes are intentionally connected and are arranged so that the anode of one diode is connected to the cathode of the other. In this configuration, the diodes can be used for two purposes. First, when an AC signal is passed between the two diodes, any signal above the forward bias of the diodes is blocked from passing by the diode. Secondly, when a DC signal is passed between the diodes, the signal will be redirected through the other diode. By doing this, the signal is rectified and the waveform is converted to a DC signal.

The IRKD91/10A utilizes a fast recovery time which allows it to be used in high-frequency applications, such as switching power supplies or stabilizes voltage regulators. This is because the fast-recovery diodes allow for much lower forward voltage drops, as well as reduce power dissipation and losses. In addition, the IRKD91/10A uses a high peak reverse voltage of 250V, making it suitable for many more power applications.

In summary, the IRKD91/10A is a fast-recovery rectifier primarily used in bridge rectifier applications. It has a nominal current rating of 1A, an optimum operating temperature range of -55 to +175°C, an average forward voltage of 1.1V, and a maximum repetitive peak reverse voltage of 250V. Its fast-recovery structure and high peak reverse voltage make it an excellent choice in many power applications, including switching power supplies and voltage regulators.
