The HER157-AP is a diode-rectifier that features a single-phase silicon, offering high performance and long life. It is suitable for a variety of applications, including power conversion, filtering and signal conditioning. In this article, the HER157-AP application field and working principle will be discussed in detail.

Application Field of HER157-AP

The HER157-AP is a high voltage rectifier diode intended for use in power conversion circuits. It is suitable for use in dc-dc converters, power supplies, battery chargers and other circuits where the voltage must be converted from high to low. It can also be used in isolation circuits and signal conditioning applications.

The HER157-AP is particularly well-suited for high voltage applications, with a voltage limit of up to 1,500 volts peak. It can operate at frequencies up to 250 kHz, making it suitable for multiple high frequency applications such as switch mode power supplies, dc-ac inverters, and pulse width modulated control systems. In addition, it is also able to handle high surge or transient currents, making it a good choice for applications under peak load.

The HER157-AP is also capable of working with high current levels. It has a maximum continuous forward current of 30 amperes, and a peak repetitive surge current of 30 amperes. This makes it suitable for applications in portable electronics, relays, inductors, and other high current circuits.

Working Principle of HER157-AP

The HER157-AP is a high voltage, high current single-phase silicon rectifier. It works by using the P-N junction of the semiconductor material to conduct electric current in only one direction. When the voltage across the P-N junction is lower than a specific threshold, current will flow in the forward direction, and no current will flow in the reverse direction.

When the voltage across the P-N junction exceeds the breakdown voltage, current will start flowing in the reverse direction. This is called the avalanche breakdown mode, and can be used to regulate the voltage in voltage boosting circuits. The HER157-AP can also be used in power conditioning applications, such as voltage regulators, converters and DC-DC converters.

The HER157-AP also has a temperature coefficient of -0.15%/°C, which is lower than most other rectifiers. This means that it is capable of operating at temperatures up to 150°C without any significant decrease in performance. This makes it a suitable choice for applications where high temperatures are expected, such as automotive and industrial environments.

Conclusion

The HER157-AP is a single-phase silicon rectifier that is suitable for a variety of applications, including power conversion, filtering and signal conditioning. It is capable of operating at high frequencies up to 250 kHz and high voltages up to 1,500 volts peak. It is also able to handle large current levels and can operate at temperatures up to 150°C, making it suitable for use in harsh environments. The HER157-AP offers high performance and long life and is a good choice for a variety of applications.
