SBR20A300CTB Diodes - Rectifiers - Arrays

The SBR20A300CTB is a diode rectifier array designed to control current in a P-channel buck or boost converter. It is constructed of NPN-type transistor arrays that allow for a high degree of heat dissipation, while maintaining low conduction losses. The array has an operating temperature range of -25°C to +125°C and can handle up to a maximum voltage of 300V.

A SBR20A300CTB diode array can be used in various applications, such as extending battery life in mobile phones, protecting circuits from voltage spikes, help to reduce EMI, and more. In a buck converter, it can also be used to reduce the output voltage, allowing for more efficient operation.

To understand how the SBR20A300CTB diode array works, let’s take a look at the motor control for a buck converter. In this type of circuit, the current in the diode must be kept low because it is proportional to the load current. The SBR20A300CTB allows this to happen by utilizing a unique feature called the constant-voltage loop (CVL).

With the CVL, a second reference voltage is generated in order to prevent the current through the diode array from exceeding the set point. This second voltage is called the CVL voltage. At each cycle, if the CVL voltage is lower than the diode array’s reference voltage, the diode is allowed to draw the desired current, and the current remains constant. If the CVL voltage is higher than the reference voltage, the current through the diode array is regulated and reduced, keeping it at the set point. This feature helps to improve the efficiency of the circuit by keeping the current through the diode array lower than what it would be with a standard constant current loop.

The SBR20A300CTB diode array is able to control the current and provide efficient performance in a variety of applications. It is an ideal choice for motor control, voltage protection, and EMI reduction, and is useful for extending battery life in mobile phones. The diode array is also able to handle up to 300V, and its wide temperature range makes it suitable for a variety of applications and environments.
