GENERAL DESCRIPTION

N-channel, enhancement mode field-effect power transistor using Trench technology, intended for use in off-line

switched mode power supplies, T.V. and computer monitor power supplies, d.c. to d.c. converters, motor control circuits

and general purpose switching applications.

The IRF640 is supplied in the SOT78 (TO220AB) conventional leaded package.

The IRF640S is supplied in the SOT404 (D
