APPLICATIONS:
The 2N3439CSM4 and 2N3440CSM4 are high
voltage silicon epitaxial planar transistors mounted
in the popular 4 pin ceramic surface mount
hermetically sealed package. These products are
specifically intended for use in High reliability
systems and can be ordered with a full range of
screening options from standard Military
(equivalent to CECC Full Assessment Level)
through all options up to full space flight level.
