(Pack of 5) R4000 4000V High Voltage Rectifiers Diode DO 15

(Pack of 5) R4000 4000V High Voltage Rectifiers Diode DO 15 

The R4000 High Voltage Rectifier Diode is a high-voltage, low-current rectifier designed for applications requiring extremely high reverse voltage endurance. With a rating of 4000V (4kV) and packaged in a DO-15 axial lead package, this diode is suitable for high-voltage power supplies, multipliers, flyback transformers, and HV biasing circuits.

It offers low leakage, stable performance, and good surge handling, making it commonly used in HV generation circuits such as CRTs, laser power units, ionizers, and electrostatic systems.
