Description

IRF840 N-Channel MOSFET – High Voltage 500V, 8A, TO-220 Package

The IRF840 is an N-Channel Power MOSFET that can switch loads up to 500V. The MOSFET could switch loads that consume up to 8A. It can turn on by providing a gate threshold voltage of 10V across the Gate and Source pins. Since the MOSFET is for switching high current, high voltage loads, it has a relatively high gate voltage; hence, it cannot be used directly with an I/O pin of a CPU. If you prefer an MOSFET with low gate voltage, then try IRF540N or 2N7002, etc.
