REAR POWER METAL OXIDE SEMICONDUCTOR FIELD EFFECT TRANSISTOR (POWER MOS FET) CONSTRUCTION

id074000104900

Function

• Controls the supply voltage to the rear blower motor according to the gate voltage sent from the front climate control unit and adjusts the rotation speed (airflow volume).

Construction/Operation

• There are four electrodes: source, gate, drain and feedback electrodes.

• The resistance between terminals B and A (between drain and source) changes according to the voltage (gate voltage) applied to terminal C (gate).
• When the gate voltage increases, the resistance between terminals B and A decreases, allowing the current to flow easily.
