Part Number BVDSS RDS(on) ID
IRF440 500V 0.85Ω 8.0A
The HEXFETtechnology is the key to International
Rectifier’s adv anced line of power MOSFET transistors.
The efficient geometry and unique processing of this latest
“State of the Art” design achieves: very low on-state resistance combined with high transconductance; superior reverse energy and diode recovery dv/dt capability .
The HEXFET transistors also feature all of the well established advantages of MOSFETs such as voltage control,
very fast switching, ease of paralleling and temperature
stability of the electrical parameters.
They are well suited for applications such as switching
power supplies, motor controls, inverters, choppers, audio
amplifiers and high energy pulse circuits.
