The IRFZ40 is a rugged, through-hole TO-220 N-channel MOSFET designed for demanding power applications that require low on-resistance and fast switching. It provides robust inductive-load tolerance, an integrated body diode for free-wheeling, and good thermal performance when mounted to a heatsink. Typical uses include motor controllers, switching regulators, power switches, and general-purpose high-current switching where VDS ≤ 50 V and high pulsed/sustained currents are required. The device is made to withstand repetitive pulse stresses and includes characteristics that help reduce switching losses and EMI in practical circuits.
Features:
- N-channel enhancement MOSFET topology.
- Low conduction losses (low RDS(on)).
- Fast switching performance.
- Rugged polysilicon gate cell structure for inductive loads.
- Integrated body (flyback) diode.
- Extended safe-operating area and thermal robustness.
- TO-220 package for easy mounting and heatsinking.
