The DSA1-18D from IXYS is a single avalanche rectifier diode rated for 1800V repetitive reverse voltage and 2.3A average rectified current. Its avalanche technology provides controlled energy absorption during reverse overvoltage transients, making it a robust choice for rectification stages in power electronics. The diode reaches a forward voltage of 1.34V at a test current of 7A, with standard recovery speed above 500ns at currents above 200mA.
Suitable for line-frequency rectification and other low-speed switching circuits, the operating junction temperature range spans -40°C to 150°C, allowing use in harsh industrial environments. The DSA1-18D is provided in a radial lead through-hole package, which simplifies PCB assembly and offers reliable mechanical mounting in high-voltage designs.
As a discrete semiconductor component, this diode integrates easily into power supplies, motor drives, and other equipment requiring dependable high-voltage rectification. Its 1800V blocking capability and 2.3A current handling make it appropriate for moderate-power stages where avalanche robustness is desired.
