SNAT is Source NAT. Usually, initiated from one direction depending on configuration.
NAT - Network Address Translation
NAT is usually utilized to provide access to non-routeable addresses (RFC1918). Traffic flow initiation is bi-directional.
Internet Client <> Public IP <> {NAT Translation} <> Private IPThere are difference types of SNAT as noted here with the reasons for using them.
SNAT is usually utilized when you need to translate the original client IP to that of the SNAT IP. It is also used to make sure that the return traffic is passed to the F5 instead of following an asymmetric route/pathway away from the F5.

Updated my 1st comment. The 2 links should be able to provide an answer. If you have specific scenario that you are trying to solve with SNAT or NAT, explaining the scenario will help someone to provide the better option between SNAT and NAT.
