Description
The 2N2484HR is a silicon planar epitaxial NPN
transistor specifically designed for aerospace HiRel applications and housed in hermetic
packages. It complies with the ESCC 5000
qualification standard. It is ESCC qualified
according to the 5201-001 specification. In case
of conflict between this datasheet and ESCC
detailed specification, the latter prevails.
Pin 4 in LCC-3UB connected to the lid (for ground contact)
