Solid State Relays for DC Load Switching

I'm working on a project and need to buy a solid state relays for DC load switching and need some advice about which is the best Mosfet to buy. The project consists of A PIR sensor connected to a 6 Volts DC motor. To achieve this I need a solid state relays for DC load switching of the motor.

Here are the specifications of the project:

Specifications:-

• Voltage range of output 4.8VDC - 7.2V (motor)

• Input:-

Min turn-on voltage/current 3.3VDC / <100uA (PIR Sensor)

Max turn-on voltage/current 5VDV / <100uA (PIR Sensor)

Min turn-off voltage 1VDC

• Output:-

Current at max. efficiency 4.5 amps (motor)

Max. permissible current 9 amps (motor)

Normal Voltage 6V (motor)

Input power 45W (motor)

Please suggest me I am waiting for reply.
