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
2
PAK) surface mounting package.
