General Description of IRFP460 MOSFET

The IRFP460 is an N-channel MOSFET manufactured by Vishay. It is designed to have a high breakdown voltage of 500V and a low on-resistance of 0.27Ω at 10V gate voltage. Given the high breakdown voltage, this MOSFET can be used in switching converters with mains voltage input, high voltage amplifiers, and motor drivers.

How To Use IRFP460 MOSFET

The MOSFET is a voltage-controlled device, meaning that a voltage must be present at the gate (with respect to the source) for it to turn on. In this case, the IRFP460 has a gate threshold voltage between 2V and 4V, and it just barely starts conducting at this voltage. To achieve the specified-on resistance of 0.27Ω, the gate voltage must be at least 10V. The maximum limit of the gate voltage is ±20V, beyond which the gate can be damaged.

Power MOSFETs like the IRFP460 are usually used in the low-side switching configuration. In the interactive simulation linked below, the MOSFET is used to switch an inductive load at a frequency of 10kHz. The diode across the inductor prevents the voltage spikes from damaging the MOSFET. The 10K pulldown resistor makes sure that the MOSFET is off by default and does not turn on accidentally.

  • DC-DC converters
  • Motor drivers
