CA3083
General Purpose High Current NPN
Transistor Array
The CA3083 is a versatile array of five high current (to
100mA) NPN transistors on a common monolithic substrate.
In addition, two of these transistors (Q1 and Q2) are
matched at low current (i.e., 1mA) for applications in which
offset parameters are of special importance.
Independent connections for each transistor plus a separate
terminal for the substrate permit maximum flexibility in circuit
design.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. The collector of each transistor of the CA3083 is isolated from the substrate by an integral diode. The substrate must be connected to a voltage
which is more negative than any collector voltage in order to maintain isolation between transistors and provide normal transistor action. To avoid
undesired coupling between transistors, the substrate Terminal (5) should be maintained at either DC or signal (AC) ground. A suitable bypass
capacitor can be used to establish a signal ground.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
