Thanks. For ex, +V is at 6V for 6V relays. If there are other ICs connected to this 6V rail and there is a back emf from the relay coil will this back emf not pass through the free wheeling diode and through the 6V rail and damage ICs conected to the 6V rail?
The circuit below says diode is connected to protect the transistor from back emf. What about other devices like ICs connected to +V. Will they not get damaged due to back emf as diode provides the path for back emf to pass through the diode up to +V and to other devices connected to +V...
