IRF740 N-Channel Power Mosfet Features, Application
The IRF740 is an N-Channel Power MOSFET that can switch loads up to 400V. This Mosfet could switch loads that use up to 10A, it can turn on by providing a gate threshold voltage of 10V across the Gate and Source pin. Since the IRF740 MOSFET is for switching high current high voltage loads it has a relatively high gate voltage, Hence, cannot be used directly with an I/O pin of a CPU. If you prefer a MOSFET with low gate voltage then try IRF520 or BSS138 etc.
One significant disadvantage of this Mosfet is its high on-resistance (RDS) cost which is about 0.55 ohms. But the IRF740 MOSFET cannot be used in applications where high switching efficiency is required. The Mosfet requires a driver circuit to provide 10volt to the gate pin of this Mosfet the easiest driver circuit can be made using a transistor. This is comparatively cheap and has very low thermal resistance, added to this MOSFET also has very good switching speeds and consequently can be used in DC-DC converter circuits.
Pin Configuration Of IRF740 N-Channel Power Mosfet
IRF740 Pinout detail Pin# Name Symbol Type Function 1 Gate G P-Type Controls the current between Drain and Source 2 Drain D N-Type Electrons Emitter(Drain) 3 Source S N-Type Electrons Collector(Source)
IRF740 Pinout consists of 3 pins in total. These pins along with names and types are given above table. Electrons flow from Drain to the source terminal. The output current depends on the voltage applied to the Gate terminal.
