Drving a SPDT 2 coil latching relay
Arjunan M R:
Does i need to care about back EMF in this relay?

Yes, back-EMF protection diodes will be required, as the datasheet doesn't say they're built-in.

Do i need to use a schotky diode?
If so will this be enough?
Here is the datasheet.

I am already using that schotky diode if it's enough I don't have to increase the BOM cost.

Does this mean that I can only energize the coil for max. of 10 ms :o.
