IRF740 Description
:
The IRF740 is a high-voltage N-channel MOSFET that is primarily used in high-voltage, high-speed switching applications. This transistor can handle a maximum load voltage of 400V. The Mosfet can switch loads consuming up to 10A when a gate threshold voltage of 10V is applied across the Gate and Source pins. Because mosfets are meant to switch high current, high voltage loads, they have a rather high gate voltage and hence cannot be utilized directly with a CPU's I/O pin. The IRF740 Mosfet has a high on-resistance (RDS) of roughly 0.55 ohms, which is a significant drawback. As a result, this mosfet cannot be used in applications that require high switching efficiency. But it can work as an amplifier and it can be used in many types of audio amplifier circuits.
