(H Suffix) PRODUCT DESCRIPTION LE 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 …
