VB30100S-M3/4W

Diodes - Rectifiers - Single

A diode is a two-terminal electronic component, typically made of silicon, with a voltage drop across its terminals in one direction only, making it a unidirectional device. The VB30100S-M3/4W is a single-phase ultrafast rectifier diode specifically designed for use in high frequency, hard-switching applications. It is ideal for switching power supply applications where a very low VF and fast recovery times are required.

Application Field

The VB30100S-M3/4W is designed for use in low power switching power supplies, such as LED drivers, AC-DC power supplies, DC-DC converters, consumer electronics, automotive and industrial electronics. Thanks to its ultrafast recovery time and low VF, it is capable of extremely high frequency, hard-switching operation, making it ideal for such applications.

Working Principle

In operation, the anode of the diode is connected to a positive voltage source while the cathode is connected to a load. When the voltage at the anode is greater than the voltage at the cathode, the diode will allow current flow. Conversely, when the anode voltage is less than the cathode voltage, the diode will block current flow. Thanks to its ultrafast recovery time, the diode can turn on and off very quickly, making it ideal for high frequency switching applications.

The VB30100S-M3/4W diode also has a low VF, which is the voltage drop across the diode when it is conducting current. This allows for a more efficient power conversion in switching power supplies, especially in applications that require a very low voltage drop.

Conclusion

In conclusion, the VB30100S-M3/4W rectifier diode is specifically designed for use in high frequency, hard-switching applications, such as LED drivers, AC-DC power supplies, DC-DC converters, consumer electronics, automotive, and industrial electronics. Its ultrafast recovery time and low VF make it ideal for such applications, allowing for more efficient power conversion.
