I don't believe so - it's n instances of a bi-valued random variable, IID. It's exactly the case the binomial distribution covers.

The Poisson distribution is what you use when the effective number of chances is "large". The Poisson distribution is effectively a special case of the binomial distribution, where the number of chances is infinity, the probability per chance is infinitesimal, and the product of the two is the expected number of events.
