Introduction to BYW98-200 Application Field and Working Principle

BYW98-200 is one of the most popular diodes in rectifier applications. Designed for maximum efficiency, it has excellent temperature characteristics over a wide spectrum of operating conditions.The main application field of the BYW98-200 is in AC-DC and DC-DC rectifier circuits in which power loss is an essential part of the design criteria. The diode is suitable for use in continuous wave (CW) and pulse-width modulation (PWM) applications. It can also operate with Pulse Width Modulated (PWM) waveforms.The BYW98-200 is comprised of a silicon junction diode, with a low forward voltage drop, an integral anode-to-cathode resistance and full-wave rectifier characteristics. In addition, its low leakage current makes this diode suitable for use in low noise applications such as industrial motor drives and audio amplifiers.

Overview of BYW98-200

BYW98-200 is a single diode used in array circuits of commercial switch power supplies and inverters, used to protect the semiconductor switches. The diode has a highly efficient low forward voltage and reverse voltage. It also has a wide temperature range, with a range of 12.5V to 25V. The device is designed with a surface mount technology and is housed in a TO-220-3 package. The package size is just 14.9mm x 11.6mm.

Working Principle of BYW98-200

The BYW98-200 is comprised of two silicon junction diodes, which function as full-wave rectifier diodes. In an alternating current (AC) circuit, it functions as a one-way rectifier, allowing current to flow in one direction. The diode has a low forward voltage drop and a high reverse voltage rating, which help to reduce power losses during conversion from AC to DC.When the BYW98-200 is in operation, the cathode of the diode is always positive. When a voltage is applied, electric current will flow from the anode to the cathode. This means that the diode can only allow current to flow from positive to negative.The BYW98-200 is also equipped with an anode-gate protection which limits the current flow when the device is exposed to high operating temperatures. This helps to protect the device from any damage caused due to thermal overloads.

Conclusion

The BYW98-200 is an essential component used in a variety of rectifier circuits. Its low forward voltage drop and high reverse voltage rating deliver excellent power efficiency and temperature characteristics. The surface mount technology, compact size and protection features make it suitable for high-speed switching applications. With its low leakage current, it is also suitable for low noise DC-DC and AC-DC conversion.
