R4000F 4000V High Voltage Rectifiers Diode DO-15

R4000F 4000V High Voltage Rectifiers Diode DO-15 is a critical component for high-power rectification and protection circuits, specifically engineered to handle extremely high reverse voltages. This high-reliability diode offers an impressive 4000 V maximum repetitive peak reverse voltage, making it indispensable in circuits where standard rectifiers would instantly fail. Consequently, the R4000F ensures robust performance and longevity in demanding applications like power supplies for X-ray equipment or high-voltage multipliers. The DO-15 axial lead package provides simple through-hole mounting. Furthermore, its low reverse leakage current and moderate forward current capability make it a highly efficient choice for converting high-voltage AC to DC or for use as a high-voltage clamp.

Key Features:

• Ultra-High Reverse Voltage: Offers a maximum repetitive peak reverse voltage (V_RRM) of 4000 V, providing exceptional protection against high voltage spikes and transients.
• High Reliability: Features a glass passivated junction, therefore, achieving superior stability and a long operational lifespan, even under challenging conditions.
• Low Reverse Leakage: Minimizes current leakage in the blocking state, which enhances efficiency and reduces unnecessary heat generation.
• Axial Lead Package: The standard DO-15 through-hole package facilitates easy manual or automated assembly into printed circuit boards.
• Fast Recovery Time: Designed with a moderately fast recovery time, making it suitable for high-voltage DC conversion stages.

Pinout and Wiring:

• Anode (Negative Lead): The lead without the color band. Connect to the input AC signal or the negative side of the circuit (in forward bias).
• Cathode (Positive Lead): The lead marked with the color band. Connect to the output DC voltage or the positive side of the circuit (in forward bias).
• Function: The diode allows current flow only from the Anode to the Cathode, thus blocking current when reverse voltage exceeds the safe limit.
