Application Scenarios & Design Considerations

Bi-Directional Triode Thyristor

Alternative Part Number

  • STP8NK80ZFP --: Same TO-220FP package and 800V/8A class N-channel MOSFET with comparable RDS(on), widely available and a direct functional substitute.
  • IRFBF20 --: 800V-class N-channel MOSFET in TO-220FP package with similar current rating, suitable as an equivalent switching device.
  • FQPF8N80C --: 800V 8A N-channel MOSFET in TO-220FP package, matching voltage and current class for the same application.
  • IRFBC40 --: 600-800V class N-channel MOSFET in TO-220 package widely used in similar switching applications; verify voltage margin for 800V rails.
  • SPP08N80C3 --: 800V CoolMOS N-channel MOSFET with similar current and on-resistance, suitable alternative for high-voltage switching designs.
