I don't have a data sheet for this tiny vibration motor: https://www.creatroninc.com/product/vibration-motor/
I will use one of the two motor drive circuits shown below.
.
Will a 1N4148 diode be adequate (100V, 300mA) as a free wheeling diode to protect Q5?
If I use the FET circuit instead can I rely on the body diode to suppress the back EMF when the motor is turned off?
