Diodes - Rectifiers - Single - CMR1U-02 BK Application Field and Working Principle

The CMR1U-02 BK is a single-diode fast-recovery rectifier designed for applications that involve both low- and high-frequency uses. The device has suitable VRRM and IRRM specifications, allowing it to be used in high-power switch-mode power supplies and other power conversion applications. The device also has fast-recovery capability, enableing it to meet the needs of high-frequency pulsed loads while maintaining diode reliability.

The CMR1U-02 BK rectifier has a wide forward drop across its terminals which increases the power efficiency by reducing reverse voltages. The reverse voltage is maintained at a safe value so as to ensure no damage is done during operation. The device is also suitable for use in Automotive Electronics applications as it is built to handle high-temperature environments.

In addition to these features, the CMR1U-02 BK rectifier is designed with a high SRF value of over 200kHz, allowing it to be used in applications with high-frequency AC input and high-bandwidth power supplies. The device has low capacitance measurement and low QRR, reducing the need for snubber circuits and enabling it to be used in very high-efficiency applications. The capacitance value of the device is also low, ensuring switching frequencies up to 1200kHz.

When it comes to the working principle of the CMR1U-02 BK rectifier, it is designed to allow current to flow in only one direction (called the forward direction). The reverse voltage is clamped to a certain value. When the device is biased in the forward direction, current will flow through the diode. As current flows through the diode, a voltage drop is created across it, resulting in the reduction in voltage.

During reverse bias operation, no current will flow through the device, and the reverse voltage will be clamped to a certain value regardless of the value of the reverse voltage being applied to the diode. The device is designed to offer high recover time (<20ns). The reverse recovery time is greatly reduced by the use of a low-capacitance design.

The CMR1U-02 BK rectifier is used in a variety of applications ranging from AC/DC converters, battery charge controllers, power supplies, and inverters. This device has the advantages of being able to operate at higher switching frequencies, provide a high-power efficiency, handle large reverse-bias voltage, and having a low QRR and low capacitance. This type of diode is a great choice for power conversion applications such as AC/DC converters and power supplies.
