2N3439 thru 2N3440
NPN LOW POWER SILICON
TRANSISTOR
Qualified per MIL-PRF-19500/368
DESCRIPTION
This family of high-frequency, epitaxial planar transistors feature low saturation voltage.
These devices are also available in TO-39 and low profile U4 and UA packaging. Microsemi
also offers numerous other transistor products to meet higher and lower power ratings with
various switching speed requirements in both through-hole and surface-mount packages.
