GENERAL DESCRIPTION
N-channel, enhancement mode
field-effect power transistor,
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 IRF840 is supplied in the
SOT78 (TO220AB) conventional
leaded package.
