Power Adapters and Switching Power Supplies: Used in AC/DC conversion circuits, such as mobile phone chargers and LED driver power supplies.
Typical Model: FR107 (1000V/1A), reverse recovery time ≤500ns.
Medical Equipment: X-ray machines: High-voltage diodes are used to generate the high-voltage pulses required for X-rays (typically 10kV-150kV).
MRI Equipment: Assists in stabilizing the magnetic field; withstand voltage requirements are above 20kV.
Industrial Laser Equipment: Such as CO₂ laser cutting machines, requiring diodes with withstand voltages of 5kV-20kV for energy regulation.
Household Appliances: High-voltage rectifier circuits in microwave ovens (e.g., 2kV/0.5A diode HVM12).
New Energy Field: In photovoltaic inverters, diodes with withstand voltages of 1200V (e.g., STTH812) are used for DC boost.
