IRF640 vs IRF640N: Datasheet, Specifications, and FAQ

The IRF640 is an N Channel MOSFET designed for fast switching. This high-speed switching capability can be extremely useful in applications where switching speed is critical, such as a UPS circuit or any other application where a user wants to change the load input power from one source to another.

The transistor can drive a load of up to 18A and has a maximum voltage of 200V with a minimum saturation voltage of 2V to 4V at its gate. The pulsed drain current of 72A indicates that this MOSFET can drive a load of up to 72A at short intervals or when the load is not continuously connected and is only connected for 300us (Microseconds) with a duty cycle of 1.5%.

The IR MOSFET series of power MOSFETs use proven silicon technologies to provide designers with a diverse device portfolio to serve a variety of applications including DC motors, inverters, SMPS, lights, load switches, and battery-powered applications. For ease of design, the devices come in a choice of surface mount and through-hole packaging with industry-standard footprints.
