GENERAL DESCRIPTION
The MAT01 is a monolithic dual NPN transistor. An exclusive
silicon nitride triple passivation process provides excellent
stability of critical parameters over both temperature and time.
Matching characteristics include offset voltage of 40 µV,
temperature drift of 0.15 µV/°C, and hFE matching of 0.7%.
High hFE is provided over a six decade range of collector
current, including an exceptional hFE of 590 at a collector
current of only 10 nA. The high gain at low collector current
makes the MAT01 ideal for use in low power, low level input
stages.

degradation of hFE and hFE matching characteristics. Do not attempt to
measure BVEBO greater than the 5 V rating.
3 Rating applies to applications using heat sinking to control case
temperature. Derate linearity at 16.4 mW/°C for case temperatures above
40°C.
4 Rating applies to applications not using heat sinking; device in free air only.
Derate linearity at 6.3 mW/°C for ambient temperatures above 70°C.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute

APPLICATIONS INFORMATION
Application of reverse bias voltages to the emitter to base junctions
in excess of ratings (5 V) may result in degradation of hFE and
hFE matching characteristics. Check circuit designs to ensure
that reverse bias voltages above 5 V cannot be applied during
transient conditions, such as at circuit turn-on and turn-off.
Stray thermoelectric voltages generated by dissimilar metals at
the contacts to the input terminals can prevent realization of the
predicted drift performance. Maintain both input terminals at
the same temperature, preferably close to the temperature of the
device package.
