COMPONENT PARTS
Smart FET
INFOID:0000000010741701
Smart FET, that uses MOS field effect transistor, is adopted for each
lamps control.
NOTE:
A MOS field effect transistor is a transistor in which the gate is com-
posed of a metal-oxide-semiconductor (MOS). Field effect transistor
is controlled by voltage, while ordinary transistor is controlled by cur-
rent. Electrode of field effect transistor is called source, drain, or
gate, while electrode of ordinary transistor is called emitter, collector,
or base.

DESCRIPTION
IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input sig-
nals from various sensors and the request signals received from control units via CAN communication.
NOTE:
To prevent to the parts, IPDM E/R integrated relays cannot be removed.
