Description
The 2N5551HR is a silicon planar epitaxial NPN
transistor in TO-18, TO-39 and LCC-3 packages.
It is specifically designed for aerospace Hi-Rel
applications and ESCC qualified according to the
5201-019 specification. In case of conflict
between this datasheet and ESCC detailed
specification, the latter prevails.
