R7221607CSOO

Diodes - Rectifiers - Single

The R7221607CSOO device is a single rectifier for general-purpose applications, such as voltage-fed, unregulated power supplies. It is targeted at cost- and space-sensitive, low to medium power efficiency applications and features low losses, allowing the device to be used in efficient power systems.

Application Field

The R7221607CSOO facilitates switching in applications such as home and automotive cooling and heating systems, medical equipment, and audio, power and HVAC systems. It is ideal for many systems where a low-cost, cost- and space-efficient, non-isolated rectification is required. Its operation is characterized by four states: on, off, open, and short, meaning it can easily be integrated into any design for power-saving, low-voltage voltage-fed rectification.

Working Principle

The R7221607CSOO utilizes an oscillator to modulate the flow of current, rapidly switching between its on/off/open/short states. This ensures minimal loss of power across the rectification process and maximizes efficiency. The oscillator operates at a frequency of up to 40kHz, yielding full power conversion with minimal harmonic distortion. The oscillator output is controlled via a PWM (pulse-width modulation) signal and the device requires an external power supply.

The device also offers several features, such as over-temperature protection and soft-start, which help protect against inrush currents. In addition, the device provides a high level of EMC (Fundamental Immunity) which reduces conducted and radiated emissions, thus ensuring an optimized system operation.

Features
