JANS 2N3498L thru JANS 2N3501L
compliant RADIATION HARDENED
NPN SILICON SWITCHING TRANSISTOR
Qualified per MIL-PRF-19500/366
Qualified Levels:
JANSM, JANSD,
JANSP, JANSL and
JANSR
DESCRIPTION
This family of JANS 2N3498L through JANS 2N3501L epitaxial, planar transistors are military
qualified in five RHA (Radiation Hardness Assurance) levels for high-reliability applications.
These devices are also available in TO-39 and low profile surface mount UB packaging.
Microsemi also offers numerous other radi ati on har de n ed transistor products to meet higher
and lower power ratings with various switching speed requirements in both through-hole and
surface-mount packages.
