PRODUCT DESCRIPTION
The design of the MAT02 series of NPN dual monolithic transistors is optimized for very low noise, low drift and low r
Precision Monolithics’ exclusive Silicon Nitride “TriplePassivation” process stabilizes the critical device parameters
over wide ranges of temperature and elapsed time. Also, the high
current gain (h
range of collector current. Exceptional characteristics of the
MAT02 include offset voltage of 50 µV max (A/E grades) and
150 µV 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 isolation between the transistors.

NOTE
Substrate is connected to case on TO-78 package.
Substrate is normally connected to the most negative
circuit potential, but can be floated.
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 Ω to 0.4 Ω. The
MAT02 electrical characteristics approach those of an ideal
transistor when operated over a collector current range of 1
µA to 10 mA. For applications requiring multiple devices
see MAT04 Quad Matched Transistor data sheet.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the MAT02 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
