I don't think so. I'm not sure if IDF ever got any A5s. Most sources list A1 and A2 variants as base for Doher.
AFAIK, all M109 based IDF SPGs ('Rochev','Doher','Dores') are based on the A1 variant. There are a few A2 examples too, but I'm not sure whether these were received to be used as experimental vehicles for upgrades, or did see actual service in artillery units.
Maybe Doher firing equipment is equivalent to that of A5, but I highly doubt any of them are built on actual A5 base vehicles (which e.g. used a newer gun - the same as A6 Paladin, not the same as earlier A1-A4 variants).
The M109 modernization project called 'HIP' (Howitzer Improvement Program) was a joint venture between the US Army and the IDF. The project's aim was to upgrade existing units to A6 level. Although the IDF pulled out of the project after two completed units only, SOME of those improvements, together with a few local upgrades, were implemented (from '95) in the 'Doher'. These locally upgraded units can't be called neither A5 (because of the different gun) nor A6 (only certain elements of the A6 upgrade level were implemented). As Pawel (rightly) pointed out, AFV Club's latest offering is clearly based on the A1 variant yet it's labelled as A2. I really hope the actual kit is accurate...
