SI-A8000

Single Diodes Overview

The Diotec Semiconductor Si-A8000/3600-1.8 is a standard recovery high voltage rectifier diode designed for demanding industrial applications. It features a repetitive peak reverse voltage of 24 kV and a rated DC voltage of 3600 V. The device supports a maximum average forward current of up to 10 A in oil cooling at 40°C, or 3.2 A under forced air conditions. It utilizes an Ø 55 x 23 mm hockey puck case with external threading for screw assembly. Key electrical characteristics include a forward voltage of less than 15 V at 2 A and a typical reverse recovery time of approximately 1500 ns.

Single Diodes Feature Summary

• High creepage and clearance distances suitable for operation in air or oil
• Supports serial cascade connection via screw mounting for higher voltage requirements
• Compliant with RoHS (exemptions 6c & 7a-I), REACH, and Conflict Minerals regulations

Single Diodes Applications

• High voltage rectification at 50/60 Hz
• Laser power supplies
• X-ray equipment
• Electrostatic dust precipitators

Single Diodes Procurement Notes

Verify the specific suffix when ordering. Suffix -Q indicates AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm thermal management requirements based on ambient temperature and cooling method (convection, forced air, or oil) as current ratings vary significantly between these modes. Ensure mechanical mounting torque does not exceed 8 Nm for M8 threads.

Single Diodes Selection Notes

Select this component for high-voltage DC conversion where robustness and isolation are critical. The hockey puck form factor allows for direct heat sinking and easy integration into large-scale power systems. Consider the trade-off between current capacity and cooling efficiency; oil immersion provides the highest current rating, while forced air offers a balance for general industrial use. Verify that the system can accommodate the physical dimensions and weight of the unit.

Single Diodes Part Context

This part belongs to the Si-A series of standard recovery high voltage rectifiers from Diotec Semiconductor. The series ranges from lower voltage models like the Si-A1125 to the high-voltage Si-A8000. These components share a common mechanical design philosophy centered on screw-mountable hockey puck packages, facilitating scalable high-voltage designs through cascading multiple units.
