Description:
The IRF840 is a high-voltage N-Channel power MOSFET designed for switching applications in power electronics. It is widely used in SMPS, inverter circuits, and high-voltage DC systems due to its ability to handle up to 500V with stable performance.

Specifications:

  • Type: N-Channel MOSFET
  • Drain-Source Voltage (Vds): 500V
  • Continuous Drain Current (Id): 8A
  • Gate Threshold Voltage: 2V – 4V
  • Rds(on): ~0.85Ω @ Vgs = 10V
  • Gate-Source Voltage: ±20V
  • Package: TO-220

Features:

  • High voltage handling capability (up to 500V)
  • Fast switching performance
  • Rugged TO-220 package for heat dissipation
