Application Scenarios & Design Considerations

N-CHANNEL 300V

Alternative Part Number

  • FQP9N30 --: N-channel 300V MOSFET in TO-220 with similar RDS(on) and current rating, widely available and pin-compatible for most through-hole designs.
  • IRF830 --: 500V N-channel MOSFET often used as a higher-voltage drop-in for 300V parts; check gate charge and RDS(on) against the STL9NK30Z in the target circuit.
  • 2SK3569 --: 500V N-channel MOSFET with comparable current capability, suitable as a functional substitute where slightly higher voltage rating is acceptable.
