PRODUCT DESCRIPTION
The design of the MAT02 series of NPN dual monolithic tran-
sistors is optimized for very low noise, low drift and low rBE.
Precision Monolithics’ exclusive Silicon Nitride “Triple-
Passivation” process stabilizes the critical device parameters
over wide ranges of temperature and elapsed time. Also, the high
current gain (hFE) of the MAT02 is maintained over a wide
range of collector current. Exceptional characteristics of the
MAT02 include offset voltage of 50
V max (A/E grades) and
150
V max F grade. Device performance is specified over the
full military temperature range as well as at 25
°C.
Input protection diodes are provided across the emitter-base
junctions to prevent degradation of the device characteristics
due to reverse-biased emitter current. The substrate is clamped
to the most negative emitter by the parasitic isolation junction
created by the protection diodes. This results in complete isola-
tion between the transistors.

The MAT02 should be used in any application where low
noise is a priority. The MAT02 can be used as an input
stage to make an amplifier with noise voltage of less than
1.0 nV/
√Hz at 100 Hz. Other applications, such as log/antilog
circuits, may use the excellent logging conformity of the
MAT02. Typical bulk resistance is only 0.3
to 0.4 . The
MAT02 electrical characteristics approach those of an ideal
transistor when operated over a collector current range of 1
A to 10 mA. For applications requiring multiple devices
see MAT04 Quad Matched Transistor data sheet.
