DESCRIPTION
The popular 1N5283UR-1 t hr u 1N5314UR-1 s er i es of 0.5 watt current r egulators provi des a
sel ection from 0.22 mA to 4.7 mA in standard 10% t ol er anc es. These de vices regulat e cur r ent
over a broad voltage range as a c ounter part offeri ng to Zen er s (t hat regulate volta ge over a
broad cu r r ent rang e). The DO-
213AB package offers a double plug internal bond connection
with a large die element for i ts uniq ue fun ction as a curr ent limiter. Microsemi al so offers
num er ous other Zener prod ucts to meet higher and lower p ower voltage r egulation
applications.
