IRF830 N-Channel Power MOSFET Transistor 4.5A 500V 1.5Ω TO-220

Description

IRF830 N-Channel Power MOSFET Transistor 4.5A 500V 1.5Ω TO-220 The IRF830 is a fast switching high voltage N-Channel MOSFET with a low on-state resistance. The Mosfet has a maximum drain to source voltage of 500V. The mosfet will have a drain to source internal resistance of 1.5Ω when triggered with 10V gate voltage. Pin Configuration Pin Number Pin Name Description 1 Source Current flows out through Source (maximum 4.5A) 2 Gate Controls the biasing of the MOSFET (Threshold voltage 10V) 3 Drain Current flows in through Drain Features N-Channel Power MOSFET Continuous Drain Current (I D ): 4.5A Gate threshold voltage (V GS-th ) is 10V (limit = ±20V) Drain to Source Breakdown Voltage: 500V Drain Source Resistance (R DS ) is 1.5 Ohms Rise time and fall time is 16nS and 16nS Available in To-220 package Note: Complete technical details can be found at the IRF830 datasheet linked at the bottom of the page Alternatives for IRF830 8N50, FTK480, KF12N50 Other N-channel MOSFETS IRF840 , IRF740 , BSS138, IRF520 , 2N7002 , BS170, BSS123, IRF3205, IRF1010E About IRF830 MOSFET The IRF840 is an N-Channel Power MOSFET which can switch loads upto 500V with a drain current of 4.5A. If you need a relatively high current Mosfet you can check the IRF840. Both Mosfet has a gate threshold voltage of 10V across the Gate and Source pin with a on-state resistance of 1.5Ω. Since the mosfet is for switching high current high voltage loads it has a relatively high gate voltage, hence cannot be used directly with a I/O pin of a CPU. If you prefer a mosfet with low gate voltage then try IRF540N or 2N7002 etc. One considerable disadvantage of the IRF830 Mosfet is its high on-resistance (R DS ) value which is about 1.5 ohms. Hence this mosfet cannot be used in applications where high switching efficiency is required. The Mosfet requires a driver circuit to provide 10V to the gate pin of this Mosfet the simplest driver circuit can be build using a transistor. It is relatively cheap and has very low thermal resistance, added to this the mosfet also has good switching speeds and hence can be used in DC-DC converter circuits.
