For operation with a *220 V** AC network, it is important to select **diodes* and a *diode bridge** that can withstand the corresponding voltages and currents. In such networks, the usual peak voltage amplitude is about **311 V* (220 V * √2), so the components must be rated for this voltage with sufficient reserve. Selecting diodes for a 220 V network 1. **Diodes**: The main parameters to pay attention to: **Reverse Voltage (VR)**: it must be higher than the peak voltage of the network (preferably about 400 V or more). **Maximum forward current (Forward Current, IF)**: must be sufficient for the expected load. Here are some common diode models that are suitable for use on a 220V network: **1N5408**: **Reverse Voltage**: up to 1000V. **Forward Current**: up to 3A. This is a powerful diode that can handle high currents and high voltages, making it suitable for most household applications. **BY550-400**: **Reverse Voltage**: up to 400V. **Forward Current**: up to 5A. Suitable for more powerful applications where higher current is required. *UF4007* (Ultrafast Diode): **Reverse Voltage**: up to 1000V. **Forward Current**: up to 1A. This is a diode for high-frequency applications, also suitable for 220V if the currents are not too high. 2. **Diode Bridge**: For a 220 V network, you can also choose ready-made *diode bridges* (bridge rectifiers). It is important that they are rated for voltage and current similar to individual diodes. Here are some examples of popular diode bridges for a 220 V network: **KBPC3510**: **Maximum reverse voltage**: up to 1000 V. **Forward current**: up to 35 A. Suitable for high-power applications where high current is required. **KBP210**: **Maximum reverse voltage**: up to 1000 V. **Forward current**: up to 2 A. Suitable for medium loads, such as consumer electronics. **GBJ2510**: **Maximum reverse voltage**: up to 1000 V. **Forward current**: up to 25 A. Suitable for more powerful circuits. Key parameters to consider: *Reverse Voltage (VR)**: should be at least **400V* (600-1000V is better for safety). **Forward Current (IF)**: depends on the expected load. For standard household devices, 2-5A is usually sufficient. For more powerful applications, choose bridges of 10A or more. Conclusion: For work with a *220V* network, diodes such as *1N5408* or *BY550-400**, as well as diode bridges such as **KBPC3510* or **KBP210** are well suited. These components are rated for high voltages and currents, making them safe for use in standard household and industrial applications.
